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]
Uniprot Description
Function: Couples tyrosine kinase signals with the activation of the Rho/Rac GTPases, thus leading to cell differentiation and/or proliferation.
Subunit structure: May interact with CCPG1
By similarity. Interacts with APS, DOCK2, GRB2, GRB3, DOCK2, SLA, TEC and ZNF655/VIK. Interacts with SIAH2; without leading to its degradation. Associates with BLNK, PLCG1, GRB2 and NCK1 in a B-cell antigen receptor-dependent fashion. Interacts with CBLB; which inhibits tyrosine phosphorylation and down-regulates activity. Interacts with SHB and CLNK
By similarity. Interacts with THEMIS2. Interacts with HCK
By similarity. Interacts with NEK3 and this interaction is prolactin-dependent. Interacts with ITK. Interacts with PTK2B/PYK2. Interacts (via SH2 domain) with SYK. Interacts with ANKRD54
By similarity. Ref.10 Ref.11 Ref.12 Ref.13 Ref.15 Ref.16 Ref.17 Ref.18 Ref.19 Ref.21 Ref.22
Tissue specificity: Widely expressed in hematopoietic cells but not in other cell types.
Domain: The DH domain is involved in interaction with CCPG1
By similarity.
Post-translational modification: Phosphorylated on tyrosine residues by HCK in response to IFNG and bacterial lipopolysaccharide (LPS)
By similarity. Phosphorylated by FYN. Ref.14
Miscellaneous: 'Vav' stands for the sixth letter of the Hebrew alphabet.
Sequence similarities: Contains 1 CH (calponin-homology) domain.Contains 1 DH (DBL-homology) domain.Contains 1 PH domain.Contains 1 phorbol-ester/DAG-type zinc finger.Contains 1 SH2 domain.Contains 2 SH3 domains.
Sequence caution: The sequence BAG62721.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.The sequence CAA34383.1 differs from that shown. Reason: Frameshift at positions 322 and 355.

Product Notes
The VAV1 vav1 (Catalog #AAA515284) is a Recombinant Protein produced from Sf9 insect cells and is intended for research purposes only. The product is available for immediate purchase. The tag for this protein is GST tag!!Expression System||Sf9 insect cells using baculovirus!!Source Note||Recombinant human VAV1 (73-end) was expressed by baculovirus in Sf9 insect cells. AAA Biotech's VAV1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Researchers should empirically determine the suitability of the VAV1 vav1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "VAV1, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
