    Summary
    Predicted to enable protein serine/threonine kinase activity. Acts upstream of or within blood vessel development. Predicted to be active in cytoplasm. Is expressed in several structures, including Kupffer's vesicle; axial mesoderm; axial vasculature; axis; and central nervous system. Human ortholog(s) of this gene implicated in ductal carcinoma in situ. Orthologous to human PAK2 (p21 (RAC1) activated kinase 2). [provided by Alliance of Genome Resources, Dec 2024]

    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.
