What is the function of this protein?
Component of the central pair apparatus of ciliary axonemes.  Plays a critical role in the function and structure of motile cilia.  May play a role in endochondral bone formation, most likely because of a function in primary cilia of chondrocytes and osteoblasts (By similarity).  Essential for normal spermatogenesis and male fertility (By similarity).  Required for normal manchette structure, transport of proteins along the manchette microtubules and formation of the sperm head and flagellum (By similarity).  Essential for sperm flagellum development and proper assembly of the respiratory motile cilia central pair apparatus, but not the brain ependymal cilia (By similarity).
What are the official names of this protein?
Sperm-associated antigen 17, Projection protein PF6 homolog.
What are the subcellular locations of this protein?
Cytoplasm. Cytoplasm, cytoskeleton, flagellum axoneme. Cytoplasmic vesicle, secretory vesicle, acrosome. Golgi apparatus. Cytoplasm, cytoskeleton. Note=Detected in the cytoplasm of round spermatids and in condensing spermatids. Localized to the central pair of the sperm flagellar axoneme. Colocalizes with SPAG6 on microtubules (By similarity). Localizes to the manchette in elongating spermatids (By similarity).
