The PAK (p21-activated kinase) family of serine/threonine kinases plays an important role in multiple cellular processes, including cytoskeletal reorganization, MAPK signaling, apoptotic signaling, etc. Binding of Rac/cdc42 to the CRIB (or PBD) domain at the N-terminal region of PAK causes autophosphorylation and conformational change of PAK. Phosphorylation of Ser21 of PAK1 or Ser20 of PAK2 regulates its binding with the adaptor protein Nck.
Suitable for use in ELISA and Western Blot. Other applications not tested.
Optimal dilutions to be determined by the researcher.
