MARCH4 Polyclonal Antibody, 100ul Buffers & Solutions The preB cell receptor isMARCH4 is a member of the MARCH family of membrane bound E3 ubiquitin ligases. MARCH enzymes add ubiquitin (see MIM 191339) to target lysines in substrate proteins, thereby signaling their vesicular transport between membrane compartments. MARCH4 reduces surface accumulation of several membrane glycoproteins by directing them to the endosomal compartment.
