Summary
Enables GTPase binding activity and protein serine/threonine kinase activity. Involved in several processes, including positive regulation of DNA biosynthetic process; positive regulation of dendritic spine morphogenesis; and positive regulation of fibroblast migration. Located in endosome. Human ortholog(s) of this gene implicated in non-syndromic X-linked intellectual disability 30. Orthologous to human PAK3 (p21 (RAC1) activated kinase 3).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
