Involved in sperm flagellum assembly.
Subcellular locations: Cell projection, Cilium, Cell projection, Cilium, Flagellum, Dynein axonemal particle, Cytoplasm
Expressed in many tissues. A smaller 0.9 kb and a larger 2.5 kb transcripts were detected at the highest level in the testis, at medium levels in the prostate, heart, liver, lung and pancreas, at low levels in the ovary, skeletal muscle and small intestine. Not detected in spleen, colon epithelium, thymus or peripheral blood leukocytes. The 0.9 kb transcript is expressed at a 20-fold higher level than the 2.5 kb transcript in the testis. Expressed in spermatozoa and airway epithelial cells (at protein level) .
