Protein
Trafficking protein particle complex subunit BET3
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Component of the TRAPP I, TRAPP II and TRAPP III complexes which act as guanine nucleotide exchange factors (GEF) for YPT1. TRAPP I plays a key role in the late stages of endoplasmic reticulum to Golgi traffic. TRAPP II plays a role in intra-Golgi transport. TRAPP III plays a role in autophagosome formation. Required for sporulation. Has a role late in meiosis following DNA replication.
Similarity
Belongs to the TRAPP small subunits family. BET3 subfamily.
