Rabaptin (IPR003914)

Short name: Rabaptin

Overlapping homologous superfamilies


Family relationships


Rabaptins interact with the GTP form of the small GTPase Rab5, a potent regulator of endocytic transport [PMID: 8521472]. Two rabaptins have been identified, rabaptin-5 and rabaptin-5beta. Both proteins bind to Rab5 and cooperate in endocytic membrane fusion [PMID: 9524116].
