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-1Sex-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. (656 aa)    
Predicted Functional Partners:
fem-2
Protein 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.

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 [...]
   
 0.993
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.
   
 
 0.989
elc-1
Skp1_POZ domain-containing protein.
    
 0.943
rbx-1
RING-box protein 1; Component of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Through the RING-type zinc finger, seems to recruit the E2 ubiquitination enzyme to the complex and brings it into close proximity to the substrate (By similarity). Essential for meiosis, mitotic chromosomal condensation and cytokinesis. Involved in histone H3 phosphorylation.
    
 0.930
elb-1
RNA polymerase II transcription factor SIII p18 subunit.
   
 0.899
zyg-11
Early embryogenesis protein zyg-11; Acts as target recruitment subunit in the E3 ubiquitin ligase complex zyg-11-cul-2-elc-1. Required for metaphase to anaphase transition and M phase exit at meiosis II. Regulates polarity establishment.
   
 
 0.872
lrr-1
Leucine-Rich Repeat protein.
   
 0.871
zer-1
Zyg eleven-related protein 1; Acts as target recruitment subunit in the E3 ubiquitin ligase complex zer-1-cul-2-elc-1.
   
 
 0.847
glp-4
Valine--tRNA ligase.
