Translocon-associated, gamma subunit (IPR009779)

Short name: TRAP-gamma

Family relationships



This family consists of several eukaryotic translocon-associated protein, gamma subunit (TRAP-gamma) sequences. The translocation site (translocon), at which nascent polypeptides pass through the endoplasmic reticulum membrane, contains a component previously called 'signal sequence receptor' that is now renamed as 'translocon-associated protein' (TRAP). The TRAP complex is comprised of four membrane proteins alpha, beta, gamma and delta, which are present in a stoichiometric relation, and are genuine neighbours in intact microsomes. The gamma subunit is predicted to span the membrane four times [PMID: 7916687].
