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

STARSteroidogenic 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). (285 aa)    
Predicted Functional Partners:
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 [...]

VDAC1
Uncharacterized protein.

CYP17A1
Steroid 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, [...]

STARD3 N-terminal like.

VDAC2
Voltage dependent anion channel 2.

MC2R
Adrenocorticotropic hormone receptor; Receptor for corticotropin (ACTH). This receptor is mediated by G proteins which activate adenylate cyclase (cAMP).
      
 0.919
VDAC3
Uncharacterized protein.
     
 0.914
FSHR
Follicle-stimulating hormone receptor; G protein-coupled receptor for follitropin, the follicle- stimulating hormone. The activity of isoform FSH-R1 is mediated by G proteins which activate adenylate cyclase. Isoform FSH-R2 and isoform FSH-R3 also bind FSH, but this does not result in activation of adenylate cyclase. Isoform FSH-R3 may be involved in calcium signaling. Through cAMP production activates the downstream PI3K-AKT and ERK1/ERK2 signaling pathways (By similarity).
   
  
 0.900
CYP19
Aromatase; Catalyzes the formation of aromatic C18 estrogens from C19 androgens.
   
 
 0.882
HSD17B3
Hydroxysteroid 17-beta dehydrogenase 3; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
