1-260 0e+00

Lipid-binding SRPBCC domain of mammalian PITPNM1-2 and related proteins (Class IIA PITPs); This subgroup includes an N-terminal SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain of mammalian Class II phosphatidylinositol transfer protein (PITPs), PITPNM1/PITPalphaI/Nir2 (PYK2 N-terminal domain-interacting receptor2) and PITPNM2/PITPalphaII/Nir3), Drosophila RdgB, and related proteins. These are membrane associated multidomain proteins belonging to the PITP family of lipid transfer proteins, and to the SRPBCC domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. In vitro, PITPs bind phosphatidylinositol (PtdIns), as well as phosphatidylcholine (PtdCho) but with a lower affinity. They transfer these lipids from one membrane compartment to another. The cellular roles of PITPs include inositol lipid signaling, PtdIns metabolism, and membrane trafficking. Ablation of the mouse gene encoding PITPNM1 results in early embryonic death. PITPNM1 is localized chiefly to the Golgi apparatus, and under certain conditions translocates to the lipid droplets. Targeting to the latter is dependent on a specific threonine residue within the SRPBCC domain. PITPNM1 plays a part in Golgi-mediated transport. It regulates diacylglycerol (DAG) production at the trans-Golgi network (TGN) via the CDP-choline pathway. Drosophila RdgB, the founding member of the PITP family, is implicated in the visual and olfactory transduction. RdgB is required for maintenance of ultra structure in photoreceptors and for sensory transduction. The mouse PITPNM1 gene rescues the phenotype of Drosophila rdgB mutant flies. In addition to the SRPBCC domain, PITPNM1 and -2 contain a Rho-inhibitory domain (Rid), six hydrophobic stretches, a DDHD calcium binding region, and a C-terminal tyrosine kinase Pyk2-binding / HAD-like phosphohydrolase domain. PITPNM1 has a role in regulating cell morphogenesis through its Rho inhibitory domain (Rid). This SRPBCC_PITPNM1-2_like domain model includes the first 52 residues of the 224 residues Rid (Rho-inhibitory domain).

Uncharacterized ACR, COG1430; Two structures have been solved for members of this large (>500 members) family of bacterial proteins present mostly in environmental bacteria and metagenomes (distant homologs are also present in several Plasmodium species). TOPSAN analysis for pdb:3pjy shows that there is much similarity with the other solved structure, pdb:3m7a, solved for UniProt:Q2GA55 (Saro_0823), a homolog of Thermotoga maritima TM1668, UniProt:Q9X1Z6., The homolog in Caulobacter crescentus (CC1388), UniProt:Q9A8G6, is associated with CspD, a cold shock protein (CC1387), UniProt:Q9A8G7. However, the genomic context of UniProt:Q2GA55 is most conserved with a putative xylose isomerase, suggesting a possible role in extracellular sugar processing. Saro_0821, UniProt:Q2GA57, is annotated as an AMP-dependent synthetase and ligase. PDB:3m7a structure corresponds to the C-terminal (27-165) fragment of the YP_496102 (Saro_0823) protein and it is structurally unique, as the best hits from Dali have a Z-score of 3.8 (1nt0, 2j1t, 3kq4) and it is thus a likely candidate for a new fold. Interestingly, many of the top Dali hits are involved in sugar metabolism. There are no obvious active site-like cavities on the protein surface of 3m7a (http://www.topsan.org/Proteins/JCSG/).

Lipid-binding SRPBCC domain of mammalian PITPNM1-2 and related proteins (Class IIA PITPs); This subgroup includes an N-terminal SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain of mammalian Class II phosphatidylinositol transfer protein (PITPs), PITPNM1/PITPalphaI/Nir2 (PYK2 N-terminal domain-interacting receptor2) and PITPNM2/PITPalphaII/Nir3), Drosophila RdgB, and related proteins. These are membrane associated multidomain proteins belonging to the PITP family of lipid transfer proteins, and to the SRPBCC domain superfamily of proteins that bind hydrophobic ligands.

1-252 1.40e-150

Phosphatidylinositol transfer protein; Along with the structurally unrelated Sec14p family (found in pfam00650), this family can bind/exchange one molecule of phosphatidylinositol (PI) or phosphatidylcholine (PC) and thus aids their transfer between different membrane compartments. There are three sub-families - all share an N-terminal PITP-like domain, whose sequence is highly conserved. It is described as consisting of three regions. The N-terminal region is thought to bind the lipid and contains two helices and an eight-stranded, mostly antiparallel beta-sheet. An intervening loop region, which is thought to play a role in protein-protein interactions, separates this from the C-terminal region, which exhibits the greatest sequence variation and may be involved in membrane binding. PITP alpha has a 16-fold greater affinity for PI than PC. Together with PITP beta, it is expressed ubiquitously in all tissues.

Uncharacterized ACR, COG1430; Two structures have been solved for members of this large (>500 members) family of bacterial proteins present mostly in environmental bacteria and metagenomes (distant homologs are also present in several Plasmodium species). TOPSAN analysis for pdb:3pjy shows that there is much similarity with the other solved structure, pdb:3m7a, solved for UniProt:Q2GA55 (Saro_0823), a homolog of Thermotoga maritima TM1668, UniProt:Q9X1Z6., The homolog in Caulobacter crescentus (CC1388), UniProt:Q9A8G6, is associated with CspD, a cold shock protein (CC1387), UniProt:Q9A8G7. However, the genomic context of UniProt:Q2GA55 is most conserved with a putative xylose isomerase, suggesting a possible role in extracellular sugar processing. Saro_0821, UniProt:Q2GA57, is annotated as an AMP-dependent synthetase and ligase. PDB:3m7a structure corresponds to the C-terminal (27-165) fragment of the YP_496102 (Saro_0823) protein and it is structurally unique, as the best hits from Dali have a Z-score of 3.8 (1nt0, 2j1t, 3kq4) and it is thus a likely candidate for a new fold. Interestingly, many of the top Dali hits are involved in sugar metabolism. There are no obvious active site-like cavities on the protein surface of 3m7a (http://www.topsan.org/Proteins/JCSG/).

Lipid-binding SRPBCC domain of mammalian PITPNM1-2 and related proteins (Class IIA PITPs); ...
1-260 0e+00

Lipid-binding SRPBCC domain of mammalian PITPNM1-2 and related proteins (Class IIA PITPs); This subgroup includes an N-terminal SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain of mammalian Class II phosphatidylinositol transfer protein (PITPs), PITPNM1/PITPalphaI/Nir2 (PYK2 N-terminal domain-interacting receptor2) and PITPNM2/PITPalphaII/Nir3), Drosophila RdgB, and related proteins. These are membrane associated multidomain proteins belonging to the PITP family of lipid transfer proteins, and to the SRPBCC domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. In vitro, PITPs bind phosphatidylinositol (PtdIns), as well as phosphatidylcholine (PtdCho) but with a lower affinity. They transfer these lipids from one membrane compartment to another. The cellular roles of PITPs include inositol lipid signaling, PtdIns metabolism, and membrane trafficking. Ablation of the mouse gene encoding PITPNM1 results in early embryonic death. PITPNM1 is localized chiefly to the Golgi apparatus, and under certain conditions translocates to the lipid droplets. Targeting to the latter is dependent on a specific threonine residue within the SRPBCC domain. PITPNM1 plays a part in Golgi-mediated transport. It regulates diacylglycerol (DAG) production at the trans-Golgi network (TGN) via the CDP-choline pathway. Drosophila RdgB, the founding member of the PITP family, is implicated in the visual and olfactory transduction. RdgB is required for maintenance of ultra structure in photoreceptors and for sensory transduction. The mouse PITPNM1 gene rescues the phenotype of Drosophila rdgB mutant flies. In addition to the SRPBCC domain, PITPNM1 and -2 contain a Rho-inhibitory domain (Rid), six hydrophobic stretches, a DDHD calcium binding region, and a C-terminal tyrosine kinase Pyk2-binding / HAD-like phosphohydrolase domain. PITPNM1 has a role in regulating cell morphogenesis through its Rho inhibitory domain (Rid). This SRPBCC_PITPNM1-2_like domain model includes the first 52 residues of the 224 residues Rid (Rho-inhibitory domain).

1-252 1.40e-150

Phosphatidylinositol transfer protein; Along with the structurally unrelated Sec14p family (found in pfam00650), this family can bind/exchange one molecule of phosphatidylinositol (PI) or phosphatidylcholine (PC) and thus aids their transfer between different membrane compartments. There are three sub-families - all share an N-terminal PITP-like domain, whose sequence is highly conserved. It is described as consisting of three regions. The N-terminal region is thought to bind the lipid and contains two helices and an eight-stranded, mostly antiparallel beta-sheet. An intervening loop region, which is thought to play a role in protein-protein interactions, separates this from the C-terminal region, which exhibits the greatest sequence variation and may be involved in membrane binding. PITP alpha has a 16-fold greater affinity for PI than PC. Together with PITP beta, it is expressed ubiquitously in all tissues.

2-259 9.50e-140

Lipid-binding SRPBCC domain of Class I and Class II Phosphatidylinositol Transfer Proteins; This family includes the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain of the phosphatidylinositol transfer protein (PITP) family of lipid transfer proteins. This family of proteins includes Class 1 PITPs (PITPNA/PITPalpha and PITPNB/PITPbeta, Drosophila vibrator and related proteins), Class IIA PITPs (PITPNM1/PITPalphaI/Nir2, PITPNM2/PITPalphaII/Nir3, Drosophila RdgB, and related proteins), and Class IIB PITPs (PITPNC1/RdgBbeta and related proteins). The PITP family belongs to the SRPBCC domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. In vitro, PITPs bind phosphatidylinositol (PtdIns), as well as phosphatidylcholine (PtdCho) but with a lower affinity. They transfer these lipids from one membrane compartment to another. The cellular roles of PITPs include inositol lipid signaling, PtdIns metabolism, and membrane trafficking. Class III PITPs, exemplified by the Sec14p family, are found in yeast and plants but are unrelated in sequence and structure to Class I and II PITPs and belong to a different superfamily.

Lipid-binding SRPBCC domain of mammalian PITPNA, -B, and related proteins (Class I PITPs); ...
2-252 1.96e-107

Lipid-binding SRPBCC domain of mammalian PITPNA, -B, and related proteins (Class I PITPs); This subgroup includes the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain of mammalian Class 1 phosphatidylinositol transfer proteins (PITPs), PITPNA/PITPalpha and PITPNB/PITPbeta, Drosophila vibrator, and related proteins. These are single domain proteins belonging to the PITP family of lipid transfer proteins, and to the SRPBCC domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. In vitro, PITPs bind phosphatidylinositol (PtdIns), as well as phosphatidylcholine (PtdCho) but with a lower affinity. They transfer these lipids from one membrane compartment to another. The cellular roles of PITPs include inositol lipid signaling, PtdIns metabolism, and membrane trafficking. In addition, PITPNB transfers sphingomyelin in vitro, with a low affinity. PITPNA is found chiefly in the nucleus and cytoplasm; it is enriched in the brain and predominantly localized in the axons. A reduced expression of PITPNA contributes to the neurodegenerative phenotype of the mouse vibrator mutation. The role of PITPNA in vivo may be to provide PtdIns for localized PI3K-dependent signaling, thereby controlling the polarized extension of axonal processes. PITPNA homozygous null mice die soon after birth from complicated organ failure, including intestinal and hepatic steatosis, hypoglycemia, and spinocerebellar disease. PITPNB is associated with the Golgi and ER, and is highly expressed in the liver. Deletion of the PITPNB gene results in embryonic lethality. The PtdIns and PtdCho exchange activity of PITPNB is required for COPI-mediated retrograde transport from the Golgi to the ER. Drosophila vibrator localizes to the ER, and has an essential role in cytokinesis during mitosis and meiosis.

Lipid-binding SRPBCC domain of mammalian PITPNC1,and related proteins (Class IIB PITPs); This subgroup includes the N-terminal SRPBCC (START/RHO_alpha_C /PITP /Bet_v1/CoxG/CalC) domain of mammalian Class IIB phosphatidylinositol transfer protein (PITP), PITPNC1/RdgBbeta, and related proteins. These are metazoan proteins belonging to the PITP family of lipid transfer proteins, and to the SRPBCC domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. In vitro, PITPs bind phosphatidylinositol (PtdIns), as well as phosphatidylcholine (PtdCho) but with a lower affinity. They transfer these lipids from one membrane compartment to another. The cellular roles of PITPs include inositol lipid signaling, PtdIns metabolism, and membrane trafficking. Mammalian PITPNC1 contains an amino-terminal SRPBCC PITP-like domain and a short carboxyl-terminal domain. It is a cytoplasmic protein, and is ubiquitously expressed. It can transfer phosphatidylinositol (PtdIns) in vitro with a similar ability to other PITPs.

702-946 7.05e-54

DDHD domain; The DDHD domain is 180 residues long and contains four conserved residues that may form a metal binding site. The domain is named after these four residues. This pattern of conservation of metal binding residues is often seen in phosphoesterase domains. This domain is found in retinal degeneration B proteins, as well as a family of probable phospholipases. It has been shown that this domain is found in a longer C terminal region that binds to PYK2 tyrosine kinase. These proteins have been called N-terminal domain-interacting receptor (Nir1, Nir2 and Nir3). This suggests that this region is involved in functionally important interactions in other members of this family.

Uncharacterized ACR, COG1430; Two structures have been solved for members of this large (>500 members) family of bacterial proteins present mostly in environmental bacteria and metagenomes (distant homologs are also present in several Plasmodium species). TOPSAN analysis for pdb:3pjy shows that there is much similarity with the other solved structure, pdb:3m7a, solved for UniProt:Q2GA55 (Saro_0823), a homolog of Thermotoga maritima TM1668, UniProt:Q9X1Z6., The homolog in Caulobacter crescentus (CC1388), UniProt:Q9A8G6, is associated with CspD, a cold shock protein (CC1387), UniProt:Q9A8G7. However, the genomic context of UniProt:Q2GA55 is most conserved with a putative xylose isomerase, suggesting a possible role in extracellular sugar processing. Saro_0821, UniProt:Q2GA57, is annotated as an AMP-dependent synthetase and ligase. PDB:3m7a structure corresponds to the C-terminal (27-165) fragment of the YP_496102 (Saro_0823) protein and it is structurally unique, as the best hits from Dali have a Z-score of 3.8 (1nt0, 2j1t, 3kq4) and it is thus a likely candidate for a new fold. Interestingly, many of the top Dali hits are involved in sugar metabolism. There are no obvious active site-like cavities on the protein surface of 3m7a (http://www.topsan.org/Proteins/JCSG/).
