Summaries for VAV1 Gene

Entrez Gene Summary for VAV1 Gene

  • This gene is a member of the VAV gene family. The VAV proteins are guanine nucleotide exchange factors (GEFs) for Rho family GTPases that activate pathways leading to actin cytoskeletal rearrangements and transcriptional alterations. The encoded protein is important in hematopoiesis, playing a role in T-cell and B-cell development and activation. The encoded protein has been identified as the specific binding partner of Nef proteins from HIV-1. Coexpression and binding of these partners initiates profound morphological changes, cytoskeletal rearrangements and the JNK/SAPK signaling cascade, leading to increased levels of viral transcription and replication. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Apr 2012]

GeneCards Summary for VAV1 Gene

VAV1 (Vav Guanine Nucleotide Exchange Factor 1) is a Protein Coding gene. Diseases associated with VAV1 include Spherocytosis, Type 1 and Common Variable Immunodeficiency. Among its related pathways are Development EGFR signaling via small GTPases and p75 NTR receptor-mediated signalling. Gene Ontology (GO) annotations related to this gene include DNA binding transcription factor activity and Rho guanyl-nucleotide exchange factor activity. An important paralog of this gene is VAV3.

UniProtKB/Swiss-Prot for VAV1 Gene

  • Couples tyrosine kinase signals with the activation of the Rho/Rac GTPases, thus leading to cell differentiation and/or proliferation.
