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. WASP is expressed primarily in hematopoietic cells, while its homolog N-WASP is widely expressed. These proteins have 48% identity in human with higher homology in the functional regions of these proteins. Phosphorylation at serine and tyrosine residues regulates the activity of both proteins. Dual phosphorylation of WASP on serine 483 and 484 by casein kinases increase the affinity for the ARP2/3 complex. WASP is tyrosine phosphorylated at tyrosine 291 after antigen receptor activation in B-cells and collagen stimulation of platelets. Phosphorylation of the analogous site in N-WASP (Tyr-256) stimulates its activity, reduces nuclear N-WASP, and is required for neurite extension.

The N-WASP phospho-regulation antibody sampler kit can be used to examine phosphorylation of N-WASP at Tyr-256 and Ser-484/Ser-485. For the latter site, phosphorylated relative to unphosphorylated Ser-484/Ser-485 can be monitored. In addition, the conserved sites in WASP (Tyr-291 and Ser-483/Ser-484) can also be examined. The kit includes polyclonal antibodies to monitor total expression levels of N-WASP and WASP.
