Has an essential role in the formation of sperm flagella and flagellar structure maintainance. It acts as a suppressor of ubiquitination and degradation of proteins involved in flagellar development and motility.
Subcellular locations: Nucleus membrane, Nucleus, Cytoplasm, Cell projection, Cilium, Flagellum
Localization varies during spermatozoa development. The protein is distributed in the nuclear membrane of the spermatogonia, in the nucleus of round spermatids, in the nucleus and cytoplasm of early elongating spermatids, in the cytoplasm of late elongating spermatids, and in the flagella of epididymal spermatozoa.
Expressed in the sperm.
