Members of the Wiskott-Aldrich sydrome protein (WASP) family regulate the formation of actin-based cell structures in many cell types. These proteins contain C-terminal actin-binding domains that can stimulate actin polymerization. In addition, these proteins bind the ARP2/3 complex, which can nucleate actin polymerization at sites that lead to branched actin structures. WASP is expressed primarily in hematopoietic cells, while its homolog N-WASP is widely expressed. These proteins have 48% identity in human with the highest homology in the functional regions of these proteins. Serine and tyrosine phosphorylation regulates the activity of both proteins. WASP is observed as a 63 kDa protein in hematopoietic cells, while N-WASP is observed as a 65 kDa in many tissues, especially brain.

Western blot analysis of Jurkat (lane 1), A431 (lane 2), and HeLa (lane 3) cell lysates (20 µg/lane). Blots were probed with rabbit polyclonal anti-WASP/N-WASP (WP2101).

Immunocytochemical labeling of N-WASP in control and pervanadate-treated A431 cells. The cells were labeled with rabbit polyclonal N-WASP/WASP (WP2101) or rabbit polyclonal N-WASP (Tyr-256) antibodies, then the antibodies were detected using appropriate secondary antibody conjugated to DyLight® 594.

A synthetic peptide (coupled to KLH) corresponding to a region near the C-terminus of human WASP. This sequence is highly homologous with a similar region in human N-WASP.

This antibody detects a 63 kDa* protein corresponding to the molecular mass of WASP on SDS-PAGE immunoblots of Jurkat cell lysate. In rat brain, A431, and SKN-SH cells, this antibody detects a 65 kDa* protein corresponding to the molecular mass of N-WASP.

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