START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC (SRPBCC) ligand-binding domain superfamily; SRPBCC domains have a deep hydrophobic ligand-binding pocket; they bind diverse ligands. Included in this superfamily are the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD1-STARD15, and the C-terminal catalytic domains of the alpha oxygenase subunit of Rieske-type non-heme iron aromatic ring-hydroxylating oxygenases (RHOs_alpha_C), as well as the SRPBCC domains of phosphatidylinositol transfer proteins (PITPs), Bet v 1 (the major pollen allergen of white birch, Betula verrucosa), CoxG, CalC, and related proteins. Other members of this superfamily include PYR/PYL/RCAR plant proteins, the aromatase/cyclase (ARO/CYC) domains of proteins such as Streptomyces glaucescens tetracenomycin, and the SRPBCC domains of Streptococcus mutans Smu.440 and related proteins.

Lipid-binding START domain of mammalian STARD2 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD2 (also known as phosphatidylcholine transfer protein/PC-TP) and related proteins. It belongs to the START domain family, and in turn to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD2 is a cytosolic phosphatidycholine (PtdCho) transfer protein, which traffics PtdCho, the most common class of phospholipids in eukaryotes, between membranes. It represents a minimal START domain structure. STARD2 plays roles in hepatic cholesterol metabolism, in the development of atherosclerosis, and may have a mitochondrial function.

Lipid-binding START domain of mammalian STARD2, -7, and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD2 (also known as phosphatidylcholine transfer protein/PC-TP), and STARD7 (also known as gestational trophoblastic tumor 1/GTT1). The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD2 is a cytosolic phosphatidycholine (PtdCho) transfer protein, which traffics PtdCho, the most common class of phospholipids in eukaryotes, between membranes. It represents a minimal START domain structure. STARD2 plays roles in hepatic cholesterol metabolism, in the development of atherosclerosis, and may also have a mitochondrial function. The gene encoding STARD7 is overexpressed in choriocarcinoma. STARD7 appears to be involved in the intracellular trafficking of PtdCho to mitochondria. STARD7 was shown to be surface active and to interact differentially with phospholipid monolayers. It showed a preference for phosphatidylserine, cholesterol, and phosphatidylglycerol.

65-211 | 6.94e-30 | |||
Lipid-binding START domain of mammalian STARD1-STARD15 and related proteins; This family includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD1-STARD15, and related domains, such as the START domain of the Arabidopsis homeobox protein GLABRA 2. The mammalian STARDs are grouped into 8 subfamilies. This family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. For some members of this family, specific lipids that bind in this pocket are known; these include cholesterol (STARD1/STARD3/ STARD4/STARD5), 25-hydroxycholesterol (STARD5), phosphatidylcholine (STARD2/ STARD7/STARD10), phosphatidylethanolamine (STARD10) and ceramides (STARD11). The START domain is found either alone or in association with other domains. Mammalian STARDs participate in the control of various cellular processes including lipid trafficking between intracellular compartments, lipid metabolism, and modulation of signaling events. Mutation or altered expression of STARDs is linked to diseases such as cancer, genetic disorders, and autoimmune disease. The Arabidopsis homeobox protein GLABRA 2 suppresses root hair formation in hairless epidermal root cells. Pssm-ID: 176851 [Multi-domain] Cd Length: 193 Bit Score: 109.74 E-value: 6.94e-30

73-211 | 1.75e-21 | |||
Lipid-binding START domain of mammalian STARD10 and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD10 (also known as CGI-52, PTCP-like, and SDCCAG28). The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD10 binds phophatidylcholine and phosphatidylethanolamine. This protein is widely expressed and is synthesized constitutively in many organs. It may function in the liver in the export of phospholipids into bile. It is concentrated in the sperm flagellum, and may play a role in energy metabolism. In the mammary gland it may participate in the enrichment of lipids in milk, and be a potential marker of differentiation. Its expression is induced in this gland during gestation and lactation. It is overexpressed in mammary tumors from Neu/ErbB2 transgenic mice, in several breast carcinoma cell lines, and in 35% of primary human breast cancers, and may cooperate with c-erbB receptor signaling in breast oncogenesis. It is a potential marker of disease outcome in breast cancer; loss of STARD10 expression in breast cancer strongly predicts an aggressive disease course. The lipid transfer activity of STRAD10 is downregulated by phosphorylation of its Ser284 by CK2 (casein kinase 2). Pssm-ID: 176880 Cd Length: 222 Bit Score: 88.47 E-value: 1.75e-21

Uncharacterized subgroup of the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domain family; Functionally uncharacterized subgroup of the START domain family. The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. For some mammalian members of the START family (STARDs), it is known which lipids bind in this pocket; these include cholesterol (STARD1, -3, -4, and -5), 25-hydroxycholesterol (STARD5), phosphatidylcholine (STARD2, -7, and -10), phosphatidylethanolamine (STARD10) and ceramides (STARD11). Mammalian STARDs participate in the control of various cellular processes, including lipid trafficking between intracellular compartments, lipid metabolism, and modulation of signaling events. Mutation or altered expression of STARDs is linked to diseases such as cancer, genetic disorders, and autoimmune disease. Pssm-ID: 176885 Cd Length: 195 Bit Score: 63.83 E-value: 1.55e-12
