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, WAVEs 1, 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.

Western blot of rat PC12 lysate. The blots were probed with anti-WAVE2 (Central region) in the presence (lane 2) or absence (lane 1) of WAVE2 (Central region) blocking peptide.

Immunocytochemical labeling of WAVE2 in rat PC12 cells differentiated with NGF. The cells were labeled with rabbit polyclonal WAVE2 (Central) antibody, then detected using appropriate secondary antibody conjugated to Cy3. The antibody was used in the absence (left) or presence (right) of blocking peptide (WX1795).



A synthetic peptide (coupled to KLH) corresponding to amino acid residues in the central region of human WAVE2. This sequence has high homology with similar regions in rat and mouse WAVE2, and has low homology to similar regions in WAVE1 and WAVE3.

This antibody was affinity purified using WAVE2 (Central region) peptide (without carrier). The antibody detects a 84 kDa* protein corresponding to the molecular mass of WAVE2 on SDS-PAGE immunoblots of human K562, mouse C2C12, and rat PC12 cells.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
