TRAP_alpha

 TRAP_alpha
PFAM accession number:PF03896
Interpro abstract (IPR005595):

The alpha-subunit of the TRAP (translocon-associated protein) complex is a single-spanning membrane protein of the endoplasmic reticulum (ER) [ (PUBMED:8050590) ]. The four-subunit (alpha, beta, gamma and delta) TRAP complex localises in the ER membrane and associates with the Sec61 translocon as a heterotetramer [ (PUBMED:15811380) ]. It also interacts with palmitoylated calnexin (CALX), the interaction is required for efficient folding of glycosylated proteins [ (PUBMED:22314232) ]. TRAP complex may also be involved in endoplasmic reticulum-associated degradation [ (PUBMED:17380188) ].

GO component:endoplasmic reticulum membrane (GO:0005789)
