 15-103 1.37e-57

Bet3-TRAPPC3 subunit of the TRAPP complex; Bet3 (also known as TRAPPC3) subunit of the trafficking protein particle complex (TRAPP). Bet3 is one of the six core subunits of TRAPP complexes which play a key role in the regulation of ER-to-Golgi and intra-Golgi transport by tethering the vesicle membrane to the target membrane. TRAPPC3 has also been shown to be additionally important for membrane fusion during the formation of vesicular tubular clusters (VTC). In its core, Bet3 forms a hydrophobic channel that also contains a conserved acylation site.

 15-98 1.11e-26

Transport protein particle (TRAPP) component; TRAPP plays a key role in the targeting and/or fusion of ER-to-Golgi transport vesicles with their acceptor compartment. TRAPP is a large multimeric protein that contains at least 10 subunits. This family contains many TRAPP family proteins. The Bet3 subunit is one of the better characterized TRAPP proteins and has a dimeric structure with hydrophobic channels. The channel entrances are located on a putative membrane-interacting surface that is distinctively flat, wide and decorated with positively charged residues. Bet3 is proposed to localize TRAPP to the Golgi.

Bet3-like domains of TRAPP; Bet3-like domains of a subfamily of core components of the trafficking protein particle complex (TRAPP) include TRAPPC3, TRAPPC5, and TRAPPC6A. TRAPP complexes play a key role in the regulation of ER-to-Golgi and intra-Golgi transport by tethering the vesicle membrane to the target membrane. TRAPPs are large multimeric protein complexes which contain six core subunits that belong to two distinct structural families, the bet3-like family and the sedlin-like family.
