Product Specifications

Immunogen

A synthetic peptide (coupled to KLH) corresponding to amino acid residues in the Dbl homology domain of human Vav2. This sequence has high homology with similar regions in rat and mouse Vav2, and has low homology to other Vav family members. [UniProt# P52735]

Specificity

The antibody detects a 100 kDa doublet corresponding to the molecular mass of Vav2 on SDS-PAGE immunoblots of human Jurkat, HUVEC, and A431 cells.

Clonality

Polyclonal

Host

Rabbit

Isotype

IgG

Theoretical MW

100 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Description

Stable for at least 1 year at -20°C.

Background: VAV2

The Vav family are Rho/Rac guanosine nucleotide exchange factors (GEFs), consisting of three members in mammalian cells (Vav, Vav2, Vav3) and one in nematodes (CelVav) (1). Vav and Vav2 are members of the dbl family of guanine nucleotide exchange factors (GEF) for the rho/rac family of GTP binding proteins. Vav is expressed primarily in hematopoietic cells, while vav2 has a wider tissue distribution (2). Vav2 serves as a guanine nucleotide exchange factor for the Rho family of Ras-related GTPases. Unlike Vav1, whose expression is restricted to cells of hematopoietic origin, Vav2 is broadly expressed. Recently, Vav2 has been identified as a substrate for the epidermal growth factor (EGF) receptor. EGF receptor phosphorylates Vav2 on all three possible phosphorylation sites, Tyr-142, Tyr-159, and Tyr-172. results suggest that EGF regulates Vav2 activity basically through phosphatidylinositol 3-kinase activation, whereas tyrosine phosphorylation of Vav2 may rather be necessary for mediating protein-protein interactions (3)
