Predicted to enable several functions, including ATP binding activity; protein serine kinase activity; and protein serine/threonine kinase activity. Acts upstream of or within several processes, including anterior neural plate formation; cement gland development; and negative regulation of neuroblast proliferation. Predicted to be located in cytoplasm. Is expressed in ectoderm and nervous system. Human ortholog(s) of this gene implicated in non-syndromic X-linked intellectual disability 30. Orthologous to human PAK3 (p21 (RAC1) activated kinase 3).
