Involved in multiple aspects of sperm assembly including acrosome attachment, shaping of the sperm head and in the early aspects of axoneme development. Not essential for primary cilium biogenesis.
Subcellular locations: Cytoplasmic vesicle, Secretory vesicle, Acrosome, Cytoplasm, Cytoskeleton, Cytoplasm, Cytoskeleton, Cilium basal body
Localizes to the acrosome and acroplaxome in round spermatids. Localizes to the manchette during spermiogenesis. Also found in the basal body of elongating spermatids, and in primary cilia of somatic cells.
