PAK3 p21 (RAC1) activated kinase 3

Gene ID: 5063, updated on 25-Jan-2022
Gene type: protein coding
Also known as: ARA; bPAK; MRX30; MRX47; OPHN3; PAK-3; XLID30; PAK3beta; beta-PAK


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.
