CC   -!- FUNCTION: May play a role in vesicular transport from endoplasmic
CC       reticulum to Golgi.
CC   -!- SUBUNIT: Part of the multisubunit transport protein particle (TRAPP)
CC       complex (PubMed:11805826). The heterodimer TRAPPC6B-TRAPPC3 interacts
CC       with TRAPPC1 likely providing a core for TRAPP complex formation
CC       (PubMed:16828797). {ECO:0000269|PubMed:11805826,
CC       ECO:0000269|PubMed:16828797}.
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus, cis-Golgi network {ECO:0000250}.
CC       Endoplasmic reticulum {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the TRAPP small subunits family. BET5 subfamily.
CC       {ECO:0000305}.
