Sperm flagellar protein 1 (SPEF1)

Microtubule-associated protein involved in the stabilization of microtubules along the axis of migration through radial intercalation. Promotes the establishment and stabilization of an axis of microtubules required for the active migration of cells into the outer epithelium (By similarity).

Microtubule- associated protein that promotes microtubule bundling and stabilizes microtubules against depolymerization in response to cold shock (By similarity). .
