VAV1 - vav guanine nucleotide exchange factor 1 Gene
Also Known as VAV
Species: Homo sapiens
About VAV1
This gene has 10 transcripts (splice variants), 209 orthologues, 22 paralogues and is associated with 72 phenotypes. Broad expression in lymph node (RPKM 23.7), appendix (RPKM 21.5) and 16 other tissues.
Summary
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]
