Vav 1 Guanine Nucleotide Exchange Factor Recombinant Protein | VAV1 recombinant protein
Recombinant Human Vav 1 Guanine Nucleotide Exchange Factor
Sterile Filtered clear solution.
Introduction: Vav 1 Guanine Nucleotide Exchange Factor (VAV1), belongs to the VAV gene family. The VAV1 proteins are guanine nucleotide exchange factors (GEFs) for Rho family GTPases which activate pathways leading to actin cytoskeletal rearrangements and transcriptional alterations. VAV1 is essential in hematopoiesis, taking part in T-cell and B-cell development and activation. VAV1 has been identified as the specific binding partner of Nef proteins from HIV-1. In addition, VAV1 contains an SH2 domain, which could show its function as a substrate for tyrosine kinases. Expression of VAV1 is limited solely to cells of hematopoietic origin, as well as those of the erythroid, lymphoid and myeloid lineages. Among the diseases associated
NCBI and Uniprot Product Information
NCBI Description
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]
