 250-458 6.26e-142

Cholesterol-binding START domain of mammalian STARD3 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD3 (also known as metastatic lymph node 64/MLN64) 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. STARD3 has a high affinity for cholesterol. It may function in trafficking endosomal cholesterol to a cytosolic acceptor or membrane. In addition to having a cytoplasmic START cholesterol-binding domain, STARD3 also contains an N-terminal MENTAL cholesterol-binding and protein-protein interaction domain. The MENTAL domain contains transmembrane helices and anchors MLN64 to endosome membranes. The gene encoding STARD3 is overexpressed in about 25% of breast cancers.

 48-232 4.22e-51

Cholesterol-capturing domain; Human meta-static lymph node (MLN) 64 is a late endosomal membrane protein, and carries this MENTAL (MLN64N-terminal) domain at its N-terminus. The domain is composed of four trans-membrane helices with three short intervening loops. The function of the domain is to capture cholesterol and pass it to the associated START domain pfam01852 for transfer to a cytosolic acceptor protein or membrane. In mammals, the MENTAL domain is involved in the localization of MLN64 and MENTHO in late endosomes, and also in homo-and of hetero-interactions of these two proteins.

 250-458 4.85e-101

Cholesterol-binding START domain of mammalian STARD1, -3 and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD1 (also known as StAR) and STARD3 (also known as metastatic lymph node 64/MLN64). 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. This STARD1-like subfamily has a high affinity for cholesterol. STARD1/StAR can reduce macrophage lipid content and inflammatory status. It plays an essential role in steroidogenic tissues: transferring the steroid precursor, cholesterol, from the outer to the inner mitochondrial membrane, across the aqueous space. Mutations in the gene encoding STARD1/StAR can cause lipid congenital adrenal hyperplasia (CAH), an autosomal recessive disorder characterized by a steroid synthesis deficiency and an accumulation of cholesterol in the adrenal glands and the gonads. STARD3 may function in trafficking endosomal cholesterol to a cytosolic acceptor or membrane. In addition to having a cytoplasmic START cholesterol-binding domain, STARD3 also contains an N-terminal MENTAL cholesterol-binding and protein-protein interaction domain. The MENTAL domain contains transmembrane helices and anchors MLN64 to endosome membranes. The gene encoding STARD3 is overexpressed in about 25% of breast cancers.

 48-232 4.22e-51

Cholesterol-capturing domain; Human meta-static lymph node (MLN) 64 is a late endosomal membrane protein, and carries this MENTAL (MLN64N-terminal) domain at its N-terminus. The domain is composed of four trans-membrane helices with three short intervening loops. The function of the domain is to capture cholesterol and pass it to the associated START domain pfam01852 for transfer to a cytosolic acceptor protein or membrane. In mammals, the MENTAL domain is involved in the localization of MLN64 and MENTHO in late endosomes, and also in homo-and of hetero-interactions of these two proteins.

 251-455 1.32e-49

Cholesterol-binding START domain of mammalian STARD1 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD1 (also known as StAR) 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. STARD1 has a high affinity for cholesterol. It can reduce macrophage lipid content and inflammatory status. It plays an essential role in steroidogenic tissues: transferring the steroid precursor, cholesterol, from the outer to the inner mitochondrial membrane, across the aqueous space. Mutations in the gene encoding STARD1/StAR can cause lipid congenital adrenal hyperplasia (CAH), an autosomal recessive disorder characterized by a steroid synthesis deficiency and an accumulation of cholesterol in the adrenal glands and the gonads.

 260-453 1.90e-28

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.

Lipid-binding START domain of mammalian STARD4, -5, -6, and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD4, -5, and -6. 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. STARD4 plays an important role in steroidogenesis, trafficking cholesterol into mitochondria. It specifically binds cholesterol, and demonstrates limited binding to another sterol, 7a-hydroxycholesterol. STARD4 and STARD5 are ubiquitously expressed, with highest levels in liver and kidney. STRAD5 functions in the kidney within the proximal tubule cells where it is associated with the Endoplasmic Reticulum (ER), and may participate in ER-associated cholesterol transport. It binds cholesterol and 25-hydroxycholesterol. Expression of the gene encoding STARD5 is increased by ER stress, and its mRNA and protein levels are elevated in a type I diabetic mouse model of human diabetic nephropathy. STARD6 is expressed in male germ cells of normal rats, and in the steroidogenic Leydig cells of perinatal hypothyroid testes. It may play a pivotal role in the steroidogenesis as well as in the spermatogenesis of normal rats. STARD6 has also been detected in the rat nervous system, and may participate in neurosteroid synthesis.

It specifically binds cholesterol, and demonstrates limited binding to another sterol, 7alpha-hydroxycholesterol. STARD4 is ubiquitously expressed, with highest levels in liver and kidney.

Lipid-binding START domain of mammalian STARDT14 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian brown fat-inducible STARD14 (also known as Acyl-Coenzyme A Thioesterase 11 or ACOT11, BFIT, THEA, THEM1, KIAA0707, and MGC25974) 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. STARD14/ACOT11 is a type II acetyl-CoA thioesterase; it catalyzes the hydrolysis of acyl-CoAs to free fatty acid and CoASH. Human STARD14 displays acetyl-CoA thioesterase activity towards medium(C12)- and long(C16)-chain fatty acyl-CoA substrates. In addition to having a START domain, most proteins in this subgroup have two tandem copies of the hotdog domain. There are two splice variants of human STARD14, named BFIT1 and BFIT2, which differ in their C-termini. Human BFIT2 is equivalent to mouse mBFIT/Acot11, whose transcription is increased two fold in obesity-resistant mice compared with obesity-prone mice.

 270-432 1.55e-03

Lipid-binding START domain of mammalian STARDT14, -15, and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian brown fat-inducible STARD14 (also known as Acyl-Coenzyme A Thioesterase 11 or ACOT11, BFIT, THEA, THEM1, KIAA0707, and MGC25974), STARD15/ACOT12 (also known as cytoplasmic acetyl-CoA hydrolase/CACH, THEAL, and MGC105114), and related domains. 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. STARD14/ACOT11 and STARD15/ACOT12 are type II acetyl-CoA thioesterases; they catalyze the hydrolysis of acyl-CoAs to free fatty acid and CoASH. Human STARD14 displays acetyl-CoA thioesterase activity towards medium(C12)- and long(C16)-chain fatty acyl-CoA substrates. Rat CACH hydrolyzes acetyl-CoA to acetate and CoA. In addition to having a START domain, STARD14 and STARD15 each have two tandem copies of the hotdog domain. There are two splice variants of human STARD14, named BFIT1 and BFIT2, which differ in their C-termini. Human BFIT2 is equivalent to mouse mBFIT/Acot11, whose transcription is increased two fold in obesity-resistant mice compared with obesity-prone mice. Human STARD15 may have roles in cholesterol metabolism and in beta-oxidation.
