SAM domain of SAM_Neurabin-like subfamily; SAM (sterile alpha motif) domain of Neurabin-like (Neural actin-binding) subfamily is a putative protein-protein interaction domain. This group currently includes the SAM domains of neurobin-I, SAMD14 and neurobin-I/SAMD14-like proteins. Most are multidomain proteins and in addition to SAM domain they contain other protein-binding domains such as PDZ and actin-binding domains. Members of this subfamily participate in signal transduction. Neurabin-I is involved in the regulation of Ca signaling intensity in alpha-adrenergic receptors; it forms a functional pair of opposing regulators with neurabin-II. Neurabins are expressed almost exclusively in neuronal cells. They are known to interact with protein phosphatase 1 and inhibit its activity; they also can bind actin filaments; however, the exact role of the SAM domain is unclear, since SAM doesn't participate in these interactions. : Pssm-ID: 188911 [Multi-domain] Cd Length: 70 Bit Score: 127.00 E-value: 6.96e-35

SAM domain of aveugle-like subfamily; SAM (sterile alpha motif) domain of SAM_aveugle-like subfamily is a protein-protein interaction domain. In Drosophila, the aveugle (AVE) protein (also known as HYP (Hyphen)) is involved in normal photoreceptor differentiation, and required for epidermal growth factor receptor (EGFR) signaling between ras and raf genes during eye development and wing vein formation. SAM domain of the HYP(AVE) protein interacts with SAM domain of CNK, the multidomain scaffold protein connector enhancer of kinase suppressor of ras. CNK/HYP(AVE) complex interacts with KSR (kinase suppressor of Ras) protein. This interaction leads to stimulation of Ras-dependent Raf activation. This subfamily also includes vertebrate AVE homologs - Samd10 and Samd12 proteins. Their exact function is unknown, but they may play a role in signal transduction during embryogenesis.

SAM domain of Polycomb group; SAM (sterile alpha motif) domain of Polycomb group is a protein-protein interaction domain. The Polycomb group includes transcriptional repressors which are involved in the regulation of some key regulatory genes during development in many organisms. They are best known for silencing Hox (Homeobox) genes. Polycomb proteins work together in large multimeric and chromatin-associated complexes. They organize chromatin of the target genes and maintain repressed states during many cell divisions. Polycomb proteins are classified based on their common function, but not on conserved domains and/or motifs; however many Polycomb proteins (members of PRC1 class complex) contain SAM domains which are more similar to each other inside of the Polycomb group than to SAM domains outside of it. Most information about structure and function of Polycomb SAM domains comes from studies of Ph (Polyhomeotic) and Scm (Sex comb on midleg) proteins. Polycomb SAM domains usually can be found at the C-terminus of the proteins. Some members of this group contain, in addition to the SAM domain, MTB repeats, Zn finger, and/or DUF3588 domains. Polycomb SAM domains can form homo- and/or heterooligomers through ML and EH surfaces. SAM/SAM oligomers apparently play a role in transcriptional repression through polymerization along the chromosome. Polycomb proteins are known to be highly expressed in some cells years before their cancer pathology; thus they are attractive markers for early cancer therapy.

At the cell level, ZO-1 and ZO-2 are involved in polarity maintenance, gene transcription, cell proliferation, and tumor cell metastasis. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ZO family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

Par3 is a scaffold protein involved in organizing cell polarity across animals. Par3 binds numerous molecules both for its recruitment to one pole of the cell and for downstream contributions to polarized cell function. It regulates cell polarity by targeting the Par complex proteins Par6 and atypical protein kinase C (aPKC) to specific cortical sites. Physical interactions between Par3 and the Par complex include Par3 PDZ domain 1 binding to the Par6 PDZ domain, Par3 PDZ domain 1 and PDZ domain 3 binding the Par6's PDZ-binding motif, and an interaction with an undefined region of aPKC that requires both Par3 PDZ2 and PDZ3. The PDZ domains of Par3 have also been implicated as potential phosphoinositide signaling integrators, since its second PDZ domain binds to phosphoinositides, and the third PDZ interacts with phosphoinositide phosphatase PTEN. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

MUPP1 contains an L27 (Lin-2 and Lin-7 binding) domain and 13 PDZ domains. PATJ (also known as INAD-like) contains an L27 domain and ten PDZ domains. PATJ lacks 3 PDZ domains seen in MUPP1: PDZ6, PDZ9, and PDZ13. This MuPP1-like PDZ9 domain is therefore absent from PATJ. MUPP1 and PATJ share several binding partners, including junctional adhesion molecules (JAM), zonula occludens (ZO)-3, Pals1 (protein associated with Lin-7), Par (partitioning defective)-6 proteins, and nectins (adherence junction adhesion molecules). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This MUPP1-like family PDZ9 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

SAM domain of Ph (polyhomeotic) proteins of Polycomb group; SAM (sterile alpha motif) domain of Ph (polyhomeotic) proteins of Polycomb group is a protein-protein interaction domain. Ph1,2,3 proteins are members of PRC1 complex. This complex is involved in transcriptional repression of Hox (Homeobox) cluster genes. It is recruited through methylated H3Lys27 and supports the repression state by mediating monoubiquitination of histone H2A. Proteins of the Ph1,2,3 subfamily contribute to anterior-posterior neural tissue specification during embryogenesis. Additionally, the P2 protein of zebrafish is known to be involved in epiboly and tailbud formation. SAM domains of Ph proteins may interact with each other, forming homooligomers, as well as with SAM domains of other proteins, in particular with the SAM domain of Scm (sex comb on midleg) proteins, forming heterooligomers. Homooligomers are similar to the ones formed by SAM Pointed domains of the TEL proteins. Such SAM/SAM oligomers apparently play a role in transcriptional repression through polymerization along the chromosome. Pssm-ID: 188976 Cd Length: 69 Bit Score: 36.61 E-value: 4.80e-03

SAM domain of STIM-1,2-like proteins; SAM (sterile alpha motif) domain of STIM-1,2-like (Stromal interaction molecule) proteins is a putative protein-protein interaction domain. STIM1 and STIM2 human proteins are type I transmembrane proteins. The N-terminal part of them includes "hidden" EF-hand and SAM domains. This region is responsible for sensing changes in store-operated and basal cytoplasmic Ca2+ levels and initiates oligomerization. "Hidden" EF hand and SAM domains have a stable intramolecular association, and the SAM domain is a component that regulates stability within STIM proteins. Destabilization of the EF-SAM association during Ca2+ depletion leads to partial unfolding and aggregation (homooligomerization), thus activating the store-operated Ca2+ entry. Immunoprecipitation analysis indicates that STIM1 and STIM2 can form co-precipitable oligomeric associations in vivo. It was suggested that STIM1 and STIM2 are involved in opposite regulation of store operated channels in plasma membrane. Pssm-ID: 188903 Cd Length: 74 Bit Score: 36.54 E-value: 4.97e-03

SAM domain of MLTK subfamily; SAM (sterile alpha motif) domain of MLTK subfamily is a protein-protein interaction domain. Besides SAM domain, these proteins have N-terminal protein tyrosine kinase domain and leucine-zipper motif. Proteins of this group act as mitogen-activated protein triple kinase in a number of MAPK cascades. They can be activated by autophosphorylation in response to stress signals. MLTK-alpha is known to phosphorylate histone H3. In mammals, MLTKs participate in the activation of the JNK/SAPK, p38, ERK5 pathways, the transcriptional factor NF-kB, in the regulation of the cell cycle checkpoint, and in the induction of apoptosis in a hepatoma cell line. Some members of this subfamily are proto-oncogenes, thus MLTK-alpha is involved in neoplasmic cell transformation and/or skin cancer development in athymic nude mice. Based on in vivo coprecipitation experiments in mammalian cells, it has been demonstrated that MLTK proteins might form homodimers/oligomers via their SAM domains.

They belong to the LAP family, which describes proteins that contain either one or four PDZ domains and 16 LRRs (leucine-rich repeats) and function in controlling cell shape, size and subcellular protein localization. In Drosophila, the Scribble complex, comprising Scribble, discs large, and lethal giant larvae, plays a role in apico-basal cell polarity, in other forms of polarity, including regulation of the actin cytoskeleton, cell signaling and vesicular trafficking, and in tumor development. Mammalian Scribble is important in many aspects of cancer development. Scribble and its homologs can be downregulated or overexpressed in cancer; they have a role in cancer beyond their function in loss of cell polarity.
