Template:ABSTRACT PUBMED 23519409
Function
[VPS9A_ARATH] Functions as guanine nucleotide exchange factor (GEF) for Rab small GTPases. Activates specifically RABF1, RABF2A and RABF2B proteins. Required for early stages of embryogenesis, cytokinesis, embryogenesis, and organ development. Is essential for the establishment or maintenance of the polar localization of the auxin efflux carrier PIN1.[1] [2] [RAF2B_ARATH] Endosomal protein that may be involved in endocytosis.[3]
