Gene Information

human ... PAK1(5058)

General description

p21 (RAC1) activated kinase 1 (PAK1) is a member of the p21-activated kinases (PAKs) which have been implicated in the regulation of cell morphology, motility and transformation. PAK1 belongs to the Group I PAKs which also includes PAK2 and PAK3. The gene encoding this protein is localized on human chromosome 11q13.

Biochem/physiol Actions

p21-activated kinases (PAKs) are serine/threonine kinases that are activated by and are effectors of small GTPases, cell division control protein 42 (CDC42) and Ras-related C3 botulinum toxin substrate (RAC). PAK1 is a key regulator of the actin cytoskeleton, adhesion and cell motility. Inactive dimeric PAK1 is mainly cytosolic and interaction with the activators Cdc42-GTP and Rac1-GTP stimulates the kinase at the sites of cellular protrusions forming adhesions to the extracellular matrix. The protein has a role in numerous cellular processes and has been shown to be expressed in squamous non-small cell lung carcinomas.

The p21-activated kinases (Paks) are serine/threonine protein kinases that bind to and, in some cases, are stimulated by activated forms of the small GTPases, Cdc42 and Rac. With the recent discovery of several novel isoforms, Paks are now categorized into
