Gene Gene information from NCBI Gene database.
Entrez ID 5063
Gene name P21 (RAC1) activated kinase 3
Gene symbol PAK3
Synonyms (NCBI Gene)
ARAMRX30MRX47OPHN3PAK-3PAK3betaXLID30bPAKbeta-PAK
Chromosome X
Chromosome location Xq23
Summary 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 s
