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

fem-2Protein phosphatase fem-2; Dephosphorylates auto-phosphorylated Ca(2+)/calmodulin- dependent protein kinase unc-43/CAMKII in vitro. Involved in the regulation of sex determination. Together with fem-3, required for male sexual development by promoting the proteasomal-mediated degradation of tra-1, a transcription repressor of male-specific genes. Promotes apoptosis. Belongs to the PP2C family. (449 aa)    
Predicted Functional Partners:
fem-1
Sex-determining protein fem-1; Sex-determining protein; essential for the adoption of the male sexual fate in all tissues. Substrate recognition subunit of the cullin-RING-based CBC(fem-1) (Cul2-ElonginB-ElonginC) E3 ubiquitin- protein ligase complex which mediates in association with cofactors fem-2 and fem-3 the ubiquitination and subsequent proteasomal degradation of tra-1.
   
 
 0.997
fem-3
Sex-determination protein fem-3; Required for male development. In XO (male) animals, fem-3 directs male differentiation in all tissues. In XX (hermaphrodite) animals, it specifies the first 80 or so germ cells to be sperm. Negatively regulates male development when bound to tra-2. Together with fem-2 associates with the CBC(fem-1) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of tra-1.
   
 
 0.995
cul-2
Cullin-2; Core component of multiple cullin-RING-based CBC (Cul2- ElonginB-ElonginC) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. As a scaffold protein may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. The functional specificity of the CBC complex depends on the variable substrate recognition component (By similarity). May function in ubiquitin-mediated degradation of CKIs to target cki-1 for degradation. CBC(zif-1) may ensure germline precursor cell [...]

tra-3
Calpain-5; Required for the correct female sexual development of the soma and germline in hermaphrodite animals, while being fully dispensable in males. Has calcium-dependent proteolytic activity and is involved in the cleavage of tra-2, for which it acts as a potentiator. Capable of calcium-dependent autolysis. Part of the necrosis cell death pathway. Required for necrosis of intestinal cells induced by B.thuringiensis endotoxin Cry6Aa ; Belongs to the peptidase C2 family.

tra-2
Sex-determining transformer protein 2; Plays a major role in controlling sexual cell fates. Promotes female development in XX animals where it sequesters one or more of the FEM proteins to the membrane thereby freeing the tra-1 protein (a putative transcription factor) to enter the nucleus and promote female development. In XO animals it acts as a receptor for her-1 which prevents it from binding to FEM proteins thereby repressing the activity of tra-1. Negatively regulates male development when bound to fem-3 and is required together with tra-1 for promoting spermatogenesis. Also requ [...]

her-1
Protein her-1; Dictates male development. Probably plays a direct role in cell signaling during C.elegans sex determination. Inhibits the function of tra-2a.
      
 0.804
tra-1
Sex-determining transformer protein 1; Plays a major role in controlling sexual phenotype. Terminal global regulator in a well-characterized cascade of sex-determining genes. Promotes female development. Interacts with tra-2 to promote spermatogenesis. Promotes spermatogenesis through the Tip60 HAT complex and by regulating the expression of genes, such as fog-3, required for male development (By similarity). Association with chromatin and at the fog-3 promoter requires wdr-5.1, and may also require wdr-5.2. With trr-1, activates the fog-3 gene to determine sperm/oocyte cell fate (By s [...]
