EMC10 is a component of the endoplasmic reticulum (ER) membrane protein complex (EMC), a conserved co- and post-translational insertase which enables the energy-independent insertion into ER membranes of newly synthesized membrane proteins [1-4]. It is involved in the co-translational insertion of multi-pass membrane proteins in which stop-transfer membrane-anchor sequences become ER membrane spanning helices. This complex controls the topology of multi-pass membrane proteins, such as G protein-coupled receptors [1,4]. This entry represents a conserved domain found in these proteins, which adopts a beta-sandwich fold.
ER membrane protein complex subunit 7, beta-sandwich domain
This is the beta-sandwich domain found in ER membrane protein complex subunit 7 (EMC7) [1,2], which is an integral membrane component of the EMC. EMC is widely conserved and involved in membrane protein biogenesis. It mediates the insertion into endo ...
This is the beta-sandwich domain found in ER membrane protein complex subunit 7 (EMC7) [1,2], which is an integral membrane component of the EMC. EMC is widely conserved and involved in membrane protein biogenesis. It mediates the insertion into endoplasmic reticulum membranes of newly synthesized membrane proteins in an energy-independent manner, both post-translational insertions of tail-anchored proteins and co-translational insertion of multipass membrane proteins [3,4]. This entry includes UPF0620 protein C83.10 from S. pombe, an orthologue of animal EMC7. This domain is also found in nodal modulators, which have been identified as part of a protein complex that participates in the nodal signalling pathway during vertebrate development [5].
ER membrane protein complex subunit 1, second beta-propeller
This is the second beta-propeller domain of ER membrane protein complex subunit 1. ER membrane protein complex subunit 1 is a component of the ER membrane protein complex (EMC, composed of EMC1, EMC2, EMC3, EMC4, EMC5 and EMC6). In Saccharomyces cere ...
This is the second beta-propeller domain of ER membrane protein complex subunit 1. ER membrane protein complex subunit 1 is a component of the ER membrane protein complex (EMC, composed of EMC1, EMC2, EMC3, EMC4, EMC5 and EMC6). In Saccharomyces cerevisiae, the EMC seems to be required for efficient folding of proteins in the endoplasmic reticulum (ER) [1]. EMC1 contains two eight-bladed beta-propellers and stabilises the entire EMC complex, contacting six of the remaining eight subunits [2]. The beta-propellers are in the lumen and may serve as a platform for recruitment of co-factors at the site of nascent protein insertion [2].
