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

Hsd3b23 beta-hydroxysteroid dehydrogenase/Delta 5-->4-isomerase type 4; 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. (373 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. 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. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate and reducing the se [...]

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, [...]

Hsd17b3
Testosterone 17-beta-dehydrogenase 3; Favors the reduction of androstenedione to testosterone. Uses NADPH while the two other EDH17B enzymes use NADH. Belongs to the short-chain dehydrogenases/reductases (SDR) family. 17-beta-HSD 3 subfamily.
  
 0.991
Cyp19a1
Aromatase; Catalyzes the formation of aromatic C18 estrogens from C19 androgens.
   
 0.981
Cyp11b2
Cytochrome P450 11B3, mitochondrial; Converts 11-deoxycorticosterone into corticosterone, 18- hydroxycorticosterone, and aldosterone. Also can catalyze the conversion of 11-deoxycortisol to cortisol, 18-hydroxycortisol and cortisone; Belongs to the cytochrome P450 family.
   
 0.981
Cyp21a1
Steroid 21-hydroxylase; Specifically catalyzes the 21-hydroxylation of steroids. Required for the adrenal synthesis of mineralocorticoids and glucocorticoids.
   
 0.979
Srd5a1
3-oxo-5-alpha-steroid 4-dehydrogenase 1; 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.
     
 0.977
Akr1c3
Aldo-keto reductase family 1 member C18; Catalyzes the conversion of progesterone into 20-alpha- dihydroprogesterone (20 alpha-OHP).
   
 
 0.965
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.
   
 0.964
Hsd17b2
Estradiol 17-beta-dehydrogenase 2; Capable of catalyzing the interconversion of testosterone and androstenedione, as well as estradiol and estrone. Favors the oxidation of estradiol and testosterone. Also has 20-alpha-HSD activity. Uses NADH while EDH17B3 uses NADPH (By similarity); Belongs to the short-chain dehydrogenases/reductases (SDR) family.
