PAK1 Antibody – Mouse Monoclonal

This gene encodes a family member of serine/threonine p21-activating kinases, known as PAK proteins. These proteins are critical effectors that link RhoGTPases to cytoskeleton reorganization and nuclear signaling, and they serve as targets for the small GTP binding proteins Cdc42 and Rac. This specific family member regulates cell motility and morphology. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

PAK1: a protein kinase of the STE20 family that regulates cell motility and morphology. Critical RhoGTPase effector that regulates cytoskeleton reorganization, the JNK MAPK pathway, and nuclear signaling. Binding of Rac/cdc42 to the PBD of PAK1 causes autophosphorylation and conformational change. Phosphorylated and activated by PDK.
