    Summary
    Enables protein serine/threonine kinase activity and protein tyrosine kinase activity. Involved in negative regulation of gluconeogenesis and protein autophosphorylation. Acts upstream of or within peptidyl-tyrosine phosphorylation and response to retinoic acid. Located in nucleus. Is expressed in several structures, including brain; genitourinary system; liver; retina; and thyroid gland. Orthologous to human CLK2 (CDC like kinase 2).

    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.
