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:
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 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

HSD17B3Testosterone 17-beta-dehydrogenase 3; Favors the reduction of androstenedione to testosterone. Uses NADPH while the two other EDH17B enzymes use NADH; Short chain dehydrogenase/reductase superfamily (310 aa)    
Predicted Functional Partners:
HSD3B1
Hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1; 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, dihydrotest [...]

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

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
   
 
 0.985
HSD17B2
Estradiol 17-beta-dehydrogenase 2; Capable of catalyzing the interconversion of testosterone and androstenedione, as well as estradiol and estrone. Also has 20-alpha-HSD activity. Uses NADH while EDH17B3 uses NADPH; Short chain dehydrogenase/reductase superfamily
     
 0.981
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
   
 
 0.980
SRD5A2
3-oxo-5-alpha-steroid 4-dehydrogenase 2; Converts testosterone (T) into 5-alpha- dihydrotestosterone (DHT) and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology
   
 
 0.980
CYP11B1
Cytochrome p450 family 11 subfamily b member 1; Cytochrome P450 11B1, mitochondrial; Has steroid 11-beta-hydroxylase activity. In addition to this activity, the 18 or 19-hydroxylation of steroids and the aromatization of androstendione to estrone have also been ascribed to cytochrome P450 XIB
     
 0.966
CYP19A1
Aromatase; Catalyzes the formation of aromatic C18 estrogens from C19 androgens; Cytochrome P450 family 19
   
 
 0.963
CYP11B2
Steroid 11beta-monooxygenase / corticosterone 18-monooxygenase; Cytochrome P450 11B2, mitochondrial; Preferentially catalyzes the conversion of 11- deoxycorticosterone to aldosterone via corticosterone and 18- hydroxycorticosterone; Belongs to the cytochrome P450 family
     
 0.953
SRD5A3
3-oxo-5-alpha-steroid 4-dehydrogenase 3 / polyprenol reductase; Polyprenol reductase; Plays a key role in early steps of protein N-linked glycosylation by being required for the conversion of polyprenol into dolichol. Dolichols are required for the synthesis of dolichol-linked monosaccharides and the oligosaccharide precursor used for N-glycosylation. Acts as a polyprenol reductase that promotes the reduction of the alpha-isoprene unit of polyprenols into dolichols in a NADP-dependent mechanism. Also able to convert testosterone (T) into 5-alpha-dihydrotestosterone (DHT)
