"CYP11A1" - Cholesterol side-chain cleavage enzyme, mitochondrial in Homo sapiens
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

CYP11A1Cholesterol side-chain cleavage enzyme, mitochondrial; Catalyzes the side-chain cleavage reaction of cholesterol to pregnenolone; Cytochrome P450 family 11 (521 aa)    
Predicted Functional Partners:
FDX1
Adrenodoxin, mitochondrial; Participates in the synthesis of thyroid hormones. Essential for the synthesis of various steroid hormones, participates in the reduction of mitochondrial cytochrome P450 for steroidogenesis. Transfers electrons from adrenodoxin reductase to CYP11A1, a cytochrome P450 that catalyzes cholesterol side-chain cleavage; Belongs to the adrenodoxin/putidaredoxin family (184 aa)
   
  0.998
STAR
Steroidogenic acute regulatory protein, mitochondrial; Plays a key role in steroid hormone synthesis by enhancing the metabolism of cholesterol into pregnenolone. Mediates the transfer of cholesterol from the outer mitochondrial membrane to the inner mitochondrial membrane where it is cleaved to pregnenolone; StAR related lipid transfer domain containing (285 aa)
      
 
  0.994
HSD3B1
3 beta-hydroxysteroid dehydrogenase/Delta 5-->4-isomerase type 1; 3-beta-HSD is a bifunctional enzyme, that catalyzes the oxidative conversion of Delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids. Efficiently catalyzes the transformation of pregnenolone to progesterone, 17-alpha-hydroxypregnenolone to 17- alpha-hydroxyprogesterone, DHEA to 4-androstenedione, dihydrotestosterone to 5-alpha-androstane-3 beta,17 beta-diol, dehydroepiandrosterone to [...] (373 aa)
      
  0.993
HSD3B2
3 beta-hydroxysteroid dehydrogenase/Delta 5-->4-isomerase type 2; 3-beta-HSD is a bifunctional enzyme, that catalyzes the oxidative conversion of Delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids; Short chain dehydrogenase/reductase superfamily (372 aa)
      
  0.987
FDXR
NADPH-adrenodoxin oxidoreductase, mitochondrial; Serves as the first electron transfer protein in all the mitochondrial P450 systems. Including cholesterol side chain cleavage in all steroidogenic tissues, steroid 11-beta hydroxylation in the adrenal cortex, 25-OH-vitamin D3-24 hydroxylation in the kidney, and sterol C-27 hydroxylation in the liver; Belongs to the ferredoxin--NADP reductase type 1 family (534 aa)
       
  0.978
CYP17A1
Steroid 17-alpha-hydroxylase/17,20 lyase; Conversion of pregnenolone and progesterone to their 17- alpha-hydroxylated products and subsequently to dehydroepiandrosterone (DHEA) and androstenedione. Catalyzes both the 17-alpha-hydroxylation and the 17,20-lyase reaction. Involved in sexual development during fetal life and at puberty; Belongs to the cytochrome P450 family (508 aa)
    
 
0.953
CYP21A2
Steroid 21-hydroxylase; Specifically catalyzes the 21-hydroxylation of steroids. Required for the adrenal synthesis of mineralocorticoids and glucocorticoids; Cytochrome P450 family 21 (495 aa)
    
 
0.944
STS
Steryl-sulfatase; Conversion of sulfated steroid precursors to estrogens during pregnancy; Sulfatases (583 aa)
          
  0.937
SULT2B1
Sulfotransferase family cytosolic 2B member 1; Sulfotransferase that utilizes 3’-phospho-5’-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs and xenobiotic compounds. Sulfonation increases the water solubility of most compounds, and therefore their renal excretion, but it can also result in bioactivation to form active metabolites. Sulfates hydroxysteroids like DHEA. Isoform 1 preferentially sulfonates cholesterol, and isoform 2 avidly sulfonates pregnenolone but not cholesterol. Plays a role in epidermal choleste [...] (365 aa)
      
 
  0.927
CYP7B1
25-hydroxycholesterol 7-alpha-hydroxylase; Oxysterol 7alpha-hydroxylase that mediates formation of 7-alpha,25-dihydroxycholesterol (7-alpha,25-OHC) from 25- hydroxycholesterol. Plays a key role in cell positioning and movement in lymphoid tissues- 7-alpha,25- dihydroxycholesterol (7-alpha,25-OHC) acts as a ligand for the G protein-coupled receptor GPR183/EBI2, a chemotactic receptor for a number of lymphoid cells (By similarity); Cytochrome P450 family 7 (506 aa)
