Enables microtubule binding activity. Involved in protein homooligomerization. Acts upstream of or within spermatid development. Located in centrosome; cytoplasm; and nucleus. Is expressed in midbrain ventricular layer and telencephalon ventricular layer. Human ortholog(s) of this gene implicated in mosaic variegated aneuploidy syndrome 2. Orthologous to human CEP57 (centrosomal protein 57). [provided by Alliance of Genome Resources, Apr 2022]
