STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

CYP17A1Steroid 17-alpha-hydroxylase/17,20 lyase; A cytochrome P450 monooxygenase involved in corticoid and androgen biosynthesis. Catalyzes 17-alpha hydroxylation of C21 steroids, which is common for both pathways. A second oxidative step, required only for androgen synthesis, involves an acyl-carbon cleavage. The 17-alpha hydroxy intermediates, as part of adrenal glucocorticoids biosynthesis pathway, are precursors of cortisol. Hydroxylates steroid hormones, pregnenolone and progesterone to form 17-alpha hydroxy metabolites, followed by the cleavage of the C17-C20 bond to form C19 steroids, [...] (509 aa)    
Predicted Functional Partners:
HSD17B3
Hydroxysteroid 17-beta dehydrogenase 3; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
   
 0.987
HSD3B1
3Beta_HSD domain-containing protein; Belongs to the 3-beta-HSD family.
   
 0.985
CYP11B1
Cytochrome P450 11B1, mitochondrial; A cytochrome P450 monooxygenase involved in the biosynthesis of adrenal corticoids. Catalyzes the hydroxylation of carbon hydrogen bond at 11-beta position of 11-deoxycortisol and 11- deoxycorticosterone/21-hydroxyprogesterone yielding cortisol or corticosterone, respectively. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate and reducing the second into a water molecule. Two electrons are provided by NADPH via a two-protein mitochondrial transfer system comprising flavoprotein FDXR (adrenodoxin/ferredoxin reductase) [...]

SRD5A1
S5A_REDUCTASE domain-containing protein.
     
 0.967
CYP11A1
Cholesterol side-chain cleavage enzyme, mitochondrial; A cytochrome P450 monooxygenase that catalyzes the side-chain hydroxylation and cleavage of cholesterol to pregnenolone, the precursor of most steroid hormones (By similarity). Catalyzes three sequential oxidation reactions of cholesterol, namely the hydroxylation at C22 followed with the hydroxylation at C20 to yield 20R,22R- hydroxycholesterol that is further cleaved between C20 and C22 to yield the C21-steroid pregnenolone and 4-methylpentanal (By similarity). Mechanistically, uses molecular oxygen inserting one oxygen atom into [...]
  
0.963
CYP19
Aromatase; Catalyzes the formation of aromatic C18 estrogens from C19 androgens.
  
0.956
HSD17B2
Uncharacterized protein; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
     
 0.946
LHCGR
Lutropin-choriogonadotropic hormone receptor; Receptor for lutropin-choriogonadotropic hormone. The activity of this receptor is mediated by G proteins which activate adenylate cyclase.
   
  
 0.944
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 (By similarity).
   
 
 0.942
SRD5A2
3-oxo-5-alpha-steroid 4-dehydrogenase; Converts testosterone into 5-alpha-dihydrotestosterone and progesterone or corticosterone into their corresponding 5-alpha-3- oxosteroids. It plays a central role in sexual differentiation and androgen physiology.
