Voltage gated calcium channels control cellular calcium entry in response to changes in membrane potential. The isoleucine-glutamine (IQ) motif in the voltage gated calcium channel IQ domain interacts with hydrophobic pockets of Ca2+/calmodulin [1]. The interaction regulates two self-regulatory calcium dependent feedback mechanism, calcium dependent inactivation (CDI), and calcium-dependent facilitation (CDF).
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 ...
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].
Voltage gated calcium channel subunit beta domain 4Aa N terminal
The beta subunit of voltage gated calcium channels is coded for by four genes 1-4. Gene 4 can produce two types of beta4A domain (beta4Aa and beta4Ab) according to how the gene splicing is carried out. This family is part of the beta4Aa N terminal do ...
The beta subunit of voltage gated calcium channels is coded for by four genes 1-4. Gene 4 can produce two types of beta4A domain (beta4Aa and beta4Ab) according to how the gene splicing is carried out. This family is part of the beta4Aa N terminal domain. It is made up of an alpha helix and a beta strand. It is thought to regulate the channel properties through protein-protein interactions with non Ca channel proteins. [1]
This is the C-terminal 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 ...
This is the C-terminal 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].
