Predicted to enable magnesium ion binding activity and protein serine/threonine kinase activity. Predicted to be involved in peptidyl-serine phosphorylation; protein autophosphorylation; and spermatid development. Predicted to be located in acrosomal vesicle and centriole. Orthologous to human TSSK2 (testis specific serine kinase 2). [provided by Alliance of Genome Resources, Apr 2022]
