The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

The third LIM domain of lipoma preferred partner (LPP); The third LIM domain of lipoma preferred partner (LPP): LPP is a member of the zyxin LIM protein family and contains three LIM zinc-binding domains at the C-terminal and proline-rich region at the N-terminal. LPP initially identified as the most frequent translocation partner of HMGA2 (High Mobility Group A2) in a subgroup of benign tumors of adipose tissue (lipomas). It was also shown to be rearranged in a number of other soft tissues, as well as in a case of acute monoblastic leukemia. In addition to its involvement in tumors, LPP was inedited as a smooth muscle restricted LIM protein that plays an important role in SMC migration. LPP is localized at sites of cell adhesion, cell-cell contacts and transiently in the nucleus. In nucleus, it acts as a coactivator for the ETS domain transcription factor PEA3. In addition to PEA3, it interacts with alpha-actinin,vasodilator stimulated phosphoprotein (VASP), Palladin, and Scrib. The LIM domains are the main focal adhesion targeting elements and that the proline- rich region, which harbors binding sites for alpha-actinin and vasodilator- stimulated phosphoprotein (VASP), has a weak targeting capacity. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The third LIM domain of Ajuba-like proteins; The third LIM domain of Ajuba-like proteins: Ajuba like LIM protein family includes three highly homologous proteins Ajuba, Limd1, and WTIP. Members of the family contain three tandem C-terminal LIM domains and a proline-rich N-terminal region. This family of proteins functions as scaffolds, participating in the assembly of numerous protein complexes. In the cytoplasm, Ajuba binds Grb2 to modulate serum-stimulated ERK activation. Ajuba also recruits the TNF receptor-associated factor 6 (TRAF6) to p62 and activates PKCKappa activity. Ajuba interacts with alpha-catenin and F-actin to contribute to the formation or stabilization of adheren junctions by linking adhesive receptors to the actin cytoskeleton. Although Ajuba is a cytoplasmic protein, it can shuttle into the nucleus. In nucleus, Ajuba functions as a corepressor for the zinc finger-protein Snail. It binds to the SNAG repression domain of Snail through its LIM region. Arginine methyltransferase-5 (Prmt5), a protein in the complex, is recruited to Snai l through an interaction with Ajuba. This ternary complex functions to repress E-cadherin, a Snail target gene. In addition, Ajuba contains functional nuclear-receptor interacting motifs and selectively interacts with retinoic acid receptors (RARs) and rexinoid receptor (RXRs) to negatively regulate retinoic acid signaling. Wtip, the Wt1-interacting protein, was originally identified as an interaction partner of the Wilms tumour protein 1 (WT1). Wtip is involved in kidney and neural crest development. Wtip interacts with the receptor tyrosine kinase Ror2 and inhibits canonical Wnt signaling. LIMD1 was reported to inhibit cell growth and metastases. The inhibition may be mediated through an interaction with the protein barrier-to-autointegration (BAF), a component of SWI/SNF chromatin-remodeling protein; or through the interaction with retinoblastoma protein (pRB), resulting in inhibition of E2F-mediated transcription, and expression of the majority of genes with E2F1- responsive elements. Recently, Limd1 was shown to interact with the p62/sequestosome protein and influence IL-1 and RANKL signaling by facilitating the assembly of a p62/TRAF6/a-PKC multi-protein complex. The Limd1-p62 interaction affects both NF-kappaB and AP-1 activity in epithelial cells and osteoclasts. Moreover, LIMD1 functions as tumor repressor to block lung tumor cell line in vitro and in vivo. Recent studies revealed that LIM proteins Wtip, LIMD1 and Ajuba interact with components of RNA induced silencing complexes (RISC) as well as eIF4E and the mRNA m7GTP cap-protein complex and are required for microRNA-mediated gene silencing. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

The second LIM domain of Thyroid receptor-interacting protein 6 (TRIP6); The second LIM domain of Thyroid receptor-interacting protein 6 (TRIP6): TRIP6 is a member of the zyxin LIM protein family and contains three LIM zinc-binding domains at the C-terminal. TRIP6 protein localizes to focal adhesion sites and along actin stress fibers. Recruitment of this protein to the plasma membrane occurs in a lysophosphatidic acid (LPA)-dependent manner. TRIP6 recruits a number of molecules involved in actin assembly, cell motility, survival and transcriptional control. The function of TRIP6 in cell motility is regulated by Src-dependent phosphorylation at a Tyr residue. The phosphorylation activates the coupling to the Crk SH2 domain, which is required for the function of TRIP6 in promoting lysophosphatidic acid (LPA)-induced cell migration. TRIP6 can shuttle to the nucleus to serve as a coactivator of AP-1 and NF-kappaB transcriptional factors. Moreover, TRIP6 can form a ternary complex with the NHERF2 PDZ protein and LPA2 receptor to regulate LPA-induced activation of ERK and AKT, rendering cells resistant to chemotherapy. Recent evidence shows that TRIP6 antagonizes Fas-Induced apoptosis by enhancing the antiapoptotic effect of LPA in cells. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of the paxillin like protein family; The first LIM domain of the paxillin like protein family: This family consists of paxillin, leupaxin, Hic-5 (ARA55), and other related proteins. There are four LIM domains in the C-terminal of the proteins and leucine-rich LD-motifs in the N-terminal region. Members of this family are adaptor proteins to recruit key components of signal-transduction machinery to specific sub-cellular locations. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. Paxillin serves as a platform for the recruitment of numerous regulatory and structural proteins that together control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression that are necessary for cell migration and survival. Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. It associates with focal adhesion kinases PYK2 and pp125FAK and identified to be a component of the osteoclast pososomal signaling complex. Hic-5 controls cell proliferation, migration and senescence by functioning as coactivator for steroid receptors such as androgen receptor, glucocorticoid receptor and progesterone receptor. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The first LIM domain of Lmx1b; The first LIM domain of Lmx1b: Lmx1b belongs to the LHX protein family, which features two tandem N-terminal LIM domains and a C-terminal DNA binding homeodomain. Members of LHX family are found in the nucleus and act as transcription factors or cofactors. LHX proteins are critical for the development of specialized cells in multiple tissue types, including the nervous system, skeletal muscle, the heart, the kidneys, and endocrine organs, such as the pituitary gland and the pancreas. In mouse, Lmx1b functions in the developing limbs and eyes, the kidneys, the brain, and in cranial mesenchyme. The disruption of Lmx1b gene results kidney and limb defects. In the brain, Lmx1b is important for generation of mesencephalic dopamine neurons and the differentiation of serotonergic neurons. In the mouse eye, Lmx1b regulates anterior segment (cornea, iris, ciliary body, trabecular meshwork, and lens) development. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The second LIM domain on actin binding LIM (abLIM) proteins; The second LIM domain of actin binding LIM (abLIM) proteins: Three homologous members of the abLIM protein family have been identified; abLIM-1, abLIM-2 and abLIM-3. The N-terminal of abLIM consists of four tandem repeats of LIM domains and the C-terminal of acting binding LIM protein is a villin headpiece domain, which has strong actin binding activity. The abLIM-1, which is expressed in retina, brain, and muscle tissue, has been indicated to function as a tumor suppressor. AbLIM-2 and -3, mainly expressed in muscle and neuronal tissue, bind to F-actin strongly. They may serve as a scaffold for signaling modules of the actin cytoskeleton and thereby modulate transcription. It has shown that LIM domains of abLIMs interact with STARS (striated muscle activator of Rho signaling), which directly binds actin and stimulates serum-response factor (SRF)-dependent transcription. All LIM domains are 50-60 amino acids in size and share two characteristic highly conserved zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The fourth LIM domain of Leupaxin; The fourth LIM domain of Leupaxin: Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. Leupaxin belongs to the paxillin focal adhesion protein family. Same as other members of the family, it has four leucine-rich LD-motifs in the N-terminus and four LIM domains in the C-terminus. It may function in cell type-specific signaling by associating with interaction partners PYK2, FAK, PEP and p95PKL. When expressed in human leukocytic cells, leupaxin significantly suppressed integrin-mediated cell adhesion to fibronectin and the tyrosine phosphorylation of paxillin. These findings indicate that leupaxin may negatively regulate the functions of paxillin during integrin signaling. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The third LIM domain of Enigma-like family; The third LIM domain of Enigma-like family: The Enigma LIM domain family is comprised of three members: Enigma, ENH, and Cypher (mouse)/ZASP (human). These subfamily members contain a single PDZ domain at the N-terminus and three LIM domains at the C-terminus. Enigma was initially characterized in humans and is expressed in multiple tissues, such as skeletal muscle, heart, bone, and brain. The third LIM domain specifically interacts with the insulin receptor and the second LIM domain interacts with the receptor tyrosine kinase Ret and the adaptor protein APS. Thus Enigma is implicated in signal transduction processes, such as mitogenic activity, insulin related actin organization, and glucose metabolism. The second member, ENH protein, was first identified in rat brain. It has been shown that ENH interacts with protein kinase D1 (PKD1) via its LIM domains and forms a complex with PKD1 and the alpha1C subunit of cardiac L-type voltage-gated calcium channel in rat neonatal cardiomyocytes. The N-terminal PDZ domain interacts with alpha-actinin at the Z-line. ZASP/Cypher is required for maintenance of Z-line structure during muscle contraction, but not required for Z-line assembly. In heart, Cypher/ZASP plays a structural role through its interaction with cytoskeletal Z-line proteins. In addition, there is increasing evidence that Cypher/ZASP also performs signaling functions. Studies reveal that Cypher/ZASP interacts with and directs PKC to the Z-line, where PKC phosphorylates downstream signaling targets. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of Lrg1p, a LIM and RhoGap domain containing protein; The first LIM domain of Lrg1p, a LIM and RhoGap domain containing protein: The members of this family contain three tandem repeats of LIM domains and a Rho-type GTPase activating protein (RhoGap) domain. Lrg1p is a Rho1 GTPase-activating protein required for efficient cell fusion in yeast. Lrg1p-GAP domain strongly and specifically stimulates the GTPase activity of Rho1p, a regulator of beta (1-3)-glucan synthase in vitro. The LIM domain is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

The first LIM domain of protein PINCH; The first LIM domain of paxillin: Paxillin is an adaptor protein, which recruits key components of the signal-transduction machinery to specific sub-cellular locations to respond to environmental changes rapidly. The C-terminal region of paxillin contains four LIM domains which target paxillin to focal adhesions, presumably through a direct association with the cytoplasmic tail of beta-integrin. The N-terminal of paxillin is leucine-rich LD-motifs. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. The binding partners of paxillin are diverse and include protein tyrosine kinases, such as Src and FAK, structural proteins, such as vinculin and actopaxin, and regulators of actin organization. Paxillin recruits these proteins to their function sites to control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The second LIM domain of the paxillin like protein family; The second LIM domain of the paxillin like protein family: This family consists of paxillin, leupaxin, Hic-5 (ARA55), and other related proteins. There are four LIM domains in the C-terminal of the proteins and leucine-rich LD-motifs in the N-terminal region. Members of this family are adaptor proteins to recruit key components of signal-transduction machinery to specific sub-cellular locations. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. Paxillin serves as a platform for the recruitment of numerous regulatory and structural proteins that together control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression that are necessary for cell migration and survival. Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. It associates with focal adhesion kinases PYK2 and pp125FAK and identified to be a component of the osteoclast pososomal signaling complex. Hic-5 controls cell proliferation, migration and senescence by functioning as coactivator for steroid receptors such as androgen receptor, glucocorticoid receptor and progesterone receptor. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.
