Protein Wiskott-Aldrich Syndrome (WASp) adalah protein yang terdiri dari 502 asam amino yang diekspresikan pada sel-sel sistem hematopoietik. Dalam keadaan tidak aktif, WASp berada dalam konformasi yang dihambat secara otomatis dengan urutan di dekat terminal-C yang mengikat ke daerah dekat terminal-N-nya. Aktivasi tergantung pada Cdc42 dan PIP2 yang bertindak untuk mengganggu interaksi ini, menyebabkan protein WASP untuk 'terbuka'. Domain yang terbuka di dekat terminal-C inilah yang mengikat dan mengaktifkan kompleks Arp2/3. Arp2/3 yang aktif selanjutnya akan memicu nukleasi F-aktin baru.

WASp adalah anggota pertama famili gen yang juga mencakup N-WASP (protein neuron Wiskott-Aldrich Syndrome), SCAR/WAVE1, WASH, WHAMM, dan JMY.^[4]^[5] WAML (seperti WASP dan MIM) dan WAWH (WASP tanpa domain WH1) baru-baru ini ditemukan.^[6]
