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 guanyl-nucleotide exchange factor activity. Involved in several processes, including negative regulation of Notch signaling pathway; positive regulation of nematode male tail tip morphogenesis; and regulation of vulval development. Predicted to be active in cytoplasm. Is expressed in several structures, including gonad; intestine; nervous system; pharynx; and tail hypodermis. Orthologous to human VAV1 (vav guanine nucleotide exchange factor 1); VAV2 (vav guanine nucleotide exchange factor 2); and VAV3 (vav guanine nucleotide exchange factor 3).

What's a GeneRIF?

We show that Rho/Rac-family GTPases and the signaling molecule inositol triphosphate (IP(3)) act downstream of VAV-1 signaling and that the VAV-1 pathway modulates rhythmic behaviors by regulating the concentration of intracellular Ca(2+).(VAV-1)
Title: The Rho/Rac-family guanine nucleotide exchange factor VAV-1 regulates rhythmic behaviors in C. elegans.
VAV-1 in the ALA interneuron also serves a critical function to suppress locomotion and feeding behavior during sleep-like quiescence
Title: A Conserved GEF for Rho-Family GTPases Acts in an EGF Signaling Pathway to Promote Sleep-like Quiescence in Caenorhabditis elegans.
The data describe a novel neuromodulatory role for VAV-1-dependent signaling in the regulation of motor circuit activity and locomotion.
Title: VAV-1 acts in a single interneuron to inhibit motor circuit activity in Caenorhabditis elegans.
results suggest that lin-12, mir-61, and vav-1 form a feedback loop that helps maximize lin-12 activity in spatial patterning 2 of vulval precursor cells
Title: LIN-12/Notch activation leads to microRNA-mediated down-regulation of Vav in C. elegans.
