STRING protein interaction network
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 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
protein homology

Gene Fusion
Mup4Major urinary protein 4; Binds pheromones, likely to displace pheromones complexed to urinary MUPs and transport them to the vomeronasal organ (VNO) where they associate with their neuronal receptor(s). MUP4 is highly specific for the male mouse pheromone 2-sec-butyl-4,5-dihydrothiazole (SBT). (178 aa)    
Predicted Functional Partners:
Major urinary protein 5; Major urinary proteins (Mups) bind pheromones, and thus stabilize them to allow slow release into the air from urine marks. May protect pheromones from oxidation. May also act as pheromones themselves. In this context, they play a role in the regulation of social behaviors, such as aggression, mating, pup-suckling, territory establishment and dominance; Belongs to the calycin superfamily. Lipocalin family.
Major urinary protein 3; Binds pheromones that are released from drying urine of males. These pheromones affect the sexual behavior of females; Belongs to the calycin superfamily. Lipocalin family.
Vomeronasal secretory protein 2; Transport of lipophilic molecules, possible pheromone- carrier.
NADPH-dependent 3-keto-steroid reductase Hsd3b5; Responsible for the reduction of the oxo group on the C-3 of 5alpha-androstane steroids. Catalyzes the conversion of dihydrotestosterone to its inactive form 5alpha-androstanediol, that does not bind androgen receptor/AR. Does not function as an isomerase.
Cytochrome P450 4A12B; A cytochrome P450 monooxygenase involved in the metabolism of fatty acids and their oxygenated derivatives (oxylipins). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase). Catalyzes predominantly the oxidation of the terminal carbon (omega- oxidation) of saturated and unsaturated fatty acids. May act as a major omega-hydroxylase for dodecanoic (lauric) acid in kidney. Participates [...]
BPI fold-containing family B, member 9B.
BPI fold-containing family A, member 6.
Odorant-binding protein 2a; May play a role in male fertility. May act as a retinoid carrier protein within the epididymis.
Secretoglobin, family 2B, member 7.
Aquaporin-5; Forms a water-specific channel (By similarity). Plays an important role in fluid secretion in salivary glands. Required for TRPV4 activation by hypotonicity. Together with TRPV4, controls regulatory volume decrease in salivary epithelial cells. Seems to play a redundant role in water transport in the eye, lung and in sweat glands. Belongs to the MIP/aquaporin (TC 1.A.8) family.
