Enables GTP binding activity and protein kinase activity. Involved in several processes, including anatomical structure morphogenesis; hemidesmosome assembly; and inductive cell migration. Located in several cellular components, including axon; hemidesmosome; and neuronal cell body. Expressed in several structures, including P5.p hermaphrodite; P7.p hermaphrodite; gonad; hypodermis; and neurons. Human ortholog(s) of this gene implicated in several diseases, including Alzheimer's disease; carcinoma (multiple); kidney cancer (multiple); and non-syndromic X-linked intellectual disability 30. Is an ortholog of human PAK1 (
p21 (RAC1) activated kinase 1); PAK2 (
p21 (RAC1) activated kinase 2); and PAK3 (
p21 (RAC1) activated kinase 3).
