The SPTLC1-SPTLC2-SPTSSA complex shows a strong preference for C16-CoA substrate, while the SPTLC1- SPTLC3-SPTSSA isozyme uses both C14-CoA and C16-CoA as substrates, with a slight preference for C14-CoA. Plays a role in MBOAT7 location to mitochondria-associated membranes (MAMs), may me involved in fatty acid remodeling phosphatidylinositol (PI). (71 aa) |
| | Sptlc3 | Serine palmitoyltransferase, long chain base subunit 3. (563 aa) |
| | Emc2 | ER membrane protein complex subunit 2; Belongs to the EMC2 family. (296 aa) |
| | Sec61g | Sec61 translocon gamma subunit. (68 aa) |
| | Mmgt1 | Membrane magnesium transporter 1; Mediates Mg(2+) transport. (131 aa) |
| | Get1 | Tail-anchored protein insertion receptor WRB; Receptor for ASNA1/TRC40-mediated insertion of tail-anchored (TA) proteins into the ER membrane. (174 aa) |
| | Dnajb11 | DnaJ homolog subfamily B member 11; As a co-chaperone for HSPA5 it is required for proper folding, trafficking or degradation of proteins. Binds directly to both unfolded proteins that are substrates for ERAD and nascent unfolded peptide chains, but dissociates from the HSPA5-unfolded protein complex before folding is completed. May help recruiting HSPA5 and other chaperones to the substrate. Stimulates HSPA5 ATPase activity. It is necessary for maturation and correct trafficking of PKD1. (358 aa) |
| | Sdf2l1 | Stromal cell-derived factor 2-like 1. (220 aa) |
| | Insig2 | Insulin-induced gene 2 protein; Mediates feedback control of cholesterol synthesis by controlling SCAP and HMGCR. Functions by blocking the processing of sterol regulatory element-binding proteins (SREBPs). Capable of retaining the SCAP-SREBF2 complex in the ER thus preventing it from escorting SREBPs to the Golgi. Seems to regulate the ubiquitin-mediated proteasomal degradation of HMGCR (By similarity). (225 aa) |
| | Calr | Calreticulin; Calcium-binding chaperone that promotes folding, oligomeric assembly and quality control in the endoplasmic reticulum (ER) via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export. Involved in maternal gene expression regulation. May participate in oocyte maturation via the regulation of calcium homeostasis. (416 aa) |
| | Tap2 | Antigen peptide transporter 2; Involved in the transport of antigens from the cytoplasm to the endoplasmic reticulum for association with MHC class I molecules. Also acts as a molecular scaffold for the final stage of MHC class I folding, namely the binding of peptide. Nascent MHC class I molecules associate with TAP via tapasin (By similarity). (703 aa) |
| | Tusc3 | Tumor suppressor candidate 3, isoform CRA_b. (347 aa) |
| | Prkcsh | Protein kinase C substrate 80K-H (Predicted), isoform CRA_b. (525 aa) |
| | Sec61a1 | Protein transport protein Sec61 subunit alpha isoform 1; Component of SEC61 channel-forming translocon complex that mediates transport of signal peptide-containing precursor polypeptides across endoplasmic reticulum (ER). Forms a ribosome receptor and a gated pore in the ER membrane, both functions required for cotranslational translocation of nascent polypeptides. May cooperate with auxiliary protein SEC62, SEC63 and HSPA5/BiP to enable post- translational transport of small presecretory proteins. Controls the passive efflux of calcium ions from the ER lumen to the cytosol through SEC [...] (476 aa) |
| | Pigt | Phosphatidylinositol glycan anchor biosynthesis, class T. (598 aa) |
| | Pdia3 | Protein disulfide-isomerase A3. (510 aa) |
| | Ppib | Peptidyl-prolyl cis-trans isomerase B; PPIase that catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and may therefore assist protein folding; Belongs to the cyclophilin-type PPIase family. PPIase B subfamily. (216 aa) |
| | Sec11c | Signal peptidase complex catalytic subunit SEC11C; Component of the microsomal signal peptidase complex which removes signal peptides from nascent proteins as they are translocated into the lumen of the endoplasmic reticulum. (192 aa) |
| | B2m | Beta-2-microglobulin; Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. (119 aa) |
