DESCRIPTION

Also known as VPS9A_ARATH, VPS9A, VPS9. 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. Homodimer. The homodimer interacts with RABF2B. Interacts with RABF1 and RABF2A.
