SMCP Proteins and Enzymes

Sperm mitochondria differ in morphology and subcellular localization from those of somatic cells. They are elongated,flattened, and arranged circumferentially to form a helical coiled sheath in the midpiece of the sperm flagellum. Theprotein encoded by this gene localizes to the capsule associated with the mitochondrial outer membranes and is thoughtto function in the organization and stabilization of the helical structure of the sperm's mitochondrial sheath.(provided by RefSeq)
