Primary source: WormBase:WBGene00004807
Locus tag: CELE_F46A9.5
See related: AllianceGenome:WB:WBGene00004807
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)
Lineage: Eukaryota; Metazoa; Ecdysozoa; Nematoda; Chromadorea; Rhabditida; Rhabditina; Rhabditomorpha; Rhabditoidea; Rhabditidae; Peloderinae; Caenorhabditis
Summary: Predicted to enable cullin family protein binding activity. Involved in several processes, including negative regulation of centrosome duplication; negative regulation of intracellular signal transduction; and regulation of synapse pruning. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including intestine; pharynx; and spermatheca. Orthologous to human SKP1 (S-phase kinase associated protein 1).

What's a GeneRIF?

We also show that SKR-1/2 functions upstream of the WD40 repeat protein WDR-23, which binds to and inhibits SKN-1. Together, these results identify a novel p38 MAPK independent signaling mechanism that activates SKN-1 via SKR-1/2 and involves WDR-23.

study found stereotyped developmental elimination of synapses in the motor neuron (HSNL) was mediated by a Skp1-cullin-F-box (SCF) complex composed of SKR-1 & SEL-10; SYG-1 bound to SKR-1 & inhibited assembly of the SCF complex, protecting nearby synapses
