Summary
Enables protein serine/threonine kinase activity. Involved in cilium assembly; hindbrain development; and smoothened signaling pathway. Acts upstream of or within several processes, including embryonic brain development; nervous system development; and positive regulation of non-motile cilium assembly. Located in centriole; ciliary basal body; and ciliary transition zone. Is expressed in nervous system. Human ortholog(s) of this gene implicated in spinocerebellar ataxia type 11. Orthologous to human TTBK2 (tau tubulin kinase 2). [provided by Alliance of Genome Resources, Apr 2022]

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.
