Summary: Enables magnesium ion binding activity and protein serine/threonine kinase activity. Involved in peptidyl-serine phosphorylation and spermatid development. Located in acrosomal vesicle and centriole. Is expressed in embryo; seminiferous tubule; spermatid; and testis. Orthologous to human TSSK2 (testis specific serine 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.
