Summary: Enables several functions, including gamma-tubulin binding activity; protein kinase binding activity; and tau-protein kinase activity. Involved in several processes, including associative learning; microtubule cytoskeleton organization; and regulation of axonogenesis. Acts upstream of or within central nervous system neuron differentiation and neuron projection morphogenesis. Located in centrosome. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Orthologous to human BRSK1 (BR serine/threonine kinase 1).

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.
