Background Information
Sperm flagellar protein 2 (SPEF2) is also named KPL2. As a cilia-associated protein, SPEF2 is broadly expressed in various cilia-related organs, such as the lung, spleen, trachea, brain, and testis (PMID: 10100999). SPEF2 is known to be essential for sperm tail development (PMID: 28619825). During spermatogenesis, SPEF2 is weakly expressed in cytoplasm in pachytene spermatocytes and round spermatocytes, then SPEF2 is localized in the manchette of steps 10-12 elongating spermatids, in the basal body at steps 13-14, and finally in the midpiece of the sperm tail at steps 14-16 (PMID: 19889948). Spef2 is expressed in the bone and cartilage, and Spef2 expression in osteoblasts increases during in vitro differentiation (PMID: 29339787).
