Western blot of human K562 cells treated with pervanadate (1 mM, 30 min) (lanes 1 & 3) then treated with alkaline phosphatase (lanes 2 & 4). The blots were probed with anti-WAVE2 (Central region) (lanes 1 & 2) or anti-WAVE (Tyr-150) (lanes 3 & 4).
Bulk Order Anti-WAVE2 (Tyr-150) [conserved site], Phosphospecific Antibody
The Wiskott–Aldrich syndrome protein (WASP) family is involved in various pathways that regulate actin cytoskeletal organization. This family includes WASP, N-WASP, and three WAVE/SCAR isoforms, WAVE1, 2, and 3. WAVE proteins play key roles in actin-mediated cell events, such as membrane ruffling and lamellipodia formation. WAVEs contain an N-terminal WAVE homology domain, a basic domain, a Proline-rich region, and carboxy terminal verprolin, cofilin, and acidic (VCA) region. WAVEs are thought to act downstream of the Rac GTPase, connecting Rac activation to induction of Arp 2/3-mediated actin polymerization. Regulation of WAVE activity can occur through tyrosine phosphorylation. Src phosphorylation of WAVE1 at Tyr-125 enhances binding to the Arp2/3 complex, and is required for WAVE inhibition of Arp2/3-mediated stress fiber formation. By contrast, WAVE2 phosphorylation of Tyr-150 by Abl may enhance Arp2/3 complex actin nucleation and microspike formation in fibroblasts. Thus, site-specific tyrosine phosphorylation may be important for controlling specific activities of WAVE proteins.
Antigen Affinity Purified
Phospho-WAVE (Tyr-150) peptide (coupled to KLH) corresponding to amino acid residues surrounding Tyr-150 in human WAVE2. This sequence has high homology with similar regions in rat and mouse WAVE2, and has homology to the conserved sites in WAVE1 (Tyr-151) and WAVE3 (Tyr-151).
Human, Mouse, Rat
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol
This antibody was cross-adsorbed to phospho-WAVE (Tyr-125) and unphosphorylated WAVE (Tyr-150) peptides before affinity purification using phospho-WAVE (Tyr-150) peptide. In western blots, the antibody detects a 78 kDa* corresponding to phosphorylated WAVE2 in K562 cells treated with pervanadate and a 80 kDa band corresponding to WAVE1 in HUVEC treated with pervanadate. It also recognizes an unidentified band near 50 kDa in K562 cells.
