Sperm flagellar protein 1

Gene

SPEF1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Microtubule-associated protein involved in the stabilization of microtubules along the axis of migration during 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).By similarity

Miscellaneous

Radial intercalation is a developmentally reiterated form of migration by which cells move in a direction orthogonal to the plane of the tissue from an inner layer to an outer layer.By similarity
