PAK3

The protein encoded by this gene is a serine-threonine kinase and forms an activated complex with GTP-bound RAS-like (P21), CDC2 and RAC1. This protein may be necessary for dendritic development and for the rapid cytoskeletal reorganization in dendritic spines associated with synaptic plasticity. Defects in this gene are the cause of a non-syndromic form of X-linked intellectual disability. Alternatively spliced transcript variants encoding different isoforms have been identified.

Interaction

Interacts tightly with GTP-bound but not GDP-bound CDC42/p21 and RAC1. Shows highly specific binding to the SH3 domains of phospholipase C-gamma and of adapter protein NCK. Interacts with the C-terminal of APP (By similarity). Interacts with ARHGEF6 and ARHGEF7. Interacts with GIT1 and GIT2 (PubMed:10896954).

Molecular function

Allosteric enzyme, Developmental protein, Kinase, Serine/threonine-protein kinase, Transferase
