Protocols

Specificity / Sensitivity

N-WASP (30D10) Rabbit mAb recognizes endogenous levels of total N-WASP protein. The antibody does not cross-react wth the hematopietic protein, WASP.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding the sequence of human N-WASP.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell types, using N-WASP (30D10) Rabbit mAb.

IP

IP

Immunoprecipitation of N-WASP from MCF-7 cells, using N-WASP (30D10) Rabbit mAb. Western blot was performed using the same antibody.

Background

Wiskott-Aldrich syndrome proteins (WASPs) mediate actin dynamics by activating the Arp2/3 actin nucleation complex in response to activated Rho family GTPases. In mammals, five WASP family members have been described. Hematopoietic WASP and ubiquitously expressed N-WASP are autoinhibited in unstimulated cells. Upon stimulation they are activated by cdc42, which relieves the autoinhibition in conjunction with phosphatidyl inositol 4,5-bisphosphate. Three WAVE (Wasf, SCAR) family proteins are similar in sequence to WASP and N-WASP but lack the WASP/N-WASP autoinhibition domains and are indirectly activated by Rac (reviewed in 1). Both WASP and WAVE functions appear to be essential, as knockout of either N-WASP or Scar-2 in mice results in cardiac and neuronal defects and embryonic lethality (2,3). Loss of WASP results in immune system defects and fewer immune cells (4). WAVE-2 (WASF2) is widely distributed, while WAVE-1 and WAVE-3 are strongly expressed in brain (5). WAVE-3 may act as a tumor suppressor in neuroblastoma, a childhood disease of the sympathetic nervous system (6). Increased expression of WAVE-3 is seen in breast cancer, and studies in breast adenocarcinoma cells indicate that WAVE-3 regulates breast cancer progression, invasion and metastasis through the p38 mitogen-activated protein kinase (MAPK) pathway (7,8).
