Serine incorporator 5 (Serinc5)

Restriction factor needed to restrict infectivity of gammaretroviruses: functions by inhibiting early measure of viral infection and impairing the ability of the viral particle to translocate its content to the cytoplasm (By similarity). Enhances the incorporation of serine into phosphatidylserine and sphingolipids.

May play a role in providing serine molecules for the formation of myelin glycosphingolipids in oligodendrocytes. .
