Calnexin (CNX) is a 67kDa integral protein of the endoplasmic reticulum (ER). It consists of a large N-terminal calcium-binding lumenal domain, a single transmembrane helix and a short, acidic cytoplasmic tail. In humans, calnexin is encoded by the gene CANX.
Furin is a protease, a proteolytic enzyme that in humans and other animals is encoded by the FURIN gene. Some proteins are inactive when they are first synthesized, and must have sections removed in order to become active. Furin cleaves these sections and activates the proteins. It was named furin because it was in the upstream region of an oncogene known as FES. The gene was known as FUR and therefore the protein was named furin. Furin is also known as PACE. A member of family S8, furin is a subtilisin-like peptidase.
Bcl-2-like protein 1 is a protein encoded in humans by the BCL2L1 gene. Through alternative splicing, the gene encodes both of the human proteins Bcl-xL and Bcl-xS.
Activating transcription factor 6, also known as ATF6, is a protein that, in humans, is encoded by the ATF6 gene and is involved in the unfolded protein response.
Binding immunoglobulin protein (BiPS) also known as 78 kDa glucose-regulated protein (GRP-78) or heat shock 70 kDa protein 5 (HSPA5) is a protein that in humans is encoded by the HSPA5 gene.
Reticulon 4, also known as Neurite outgrowth inhibitor or Nogo, is a protein that in humans is encoded by the RTN4 gene that has been identified as an inhibitor of neurite outgrowth specific to the central nervous system. During neural development Nogo is expressed mainly by neurons and provides an inhibitory signal for the migration and sprouting of CNS endothelial (tip) cells, thereby restricting blood vessel density.
B-cell receptor-associated protein 31 is a protein that in humans is encoded by the BCAP31 gene.
Proprotein convertase subtilisin/kexin type 5 is an enzyme that in humans is encoded by the PCSK5 gene, found in chromosome 9q21.3 Two alternatively spliced transcripts are described for this gene but only one has its full length nature known.
Reticulon-3 is a protein that in humans is encoded by the RTN3 gene.
Sarcoplasmic/endoplasmic reticulum calcium ATPase 3 is an enzyme that in humans is encoded by the ATP2A3 gene.
Homocysteine-responsive endoplasmic reticulum-resident ubiquitin-like domain member 1 protein is a protein that in humans is encoded by the HERPUD1 gene.
Neuroendocrine protein 7B2 is a protein that in humans is encoded by the SCG5 gene. The protein expressed by this gene is widely distributed in neuroendocrine tissues. It functions as a chaperone protein for the proprotein convertase PC2 by blocking the aggregation of this protein, and is required for the production of an active PC2 enzyme. It is an intrinsically disordered protein that may also function as a chaperone for other aggregating secretory proteins in addition to proPC2. 7B2 has been identified in vertebrates and in invertebrates as low as flatworms and insects. It is also called Sgne1 and Secretogranin V. In C. elegans, it was originally called e7B2 and then renamed Seven B Two. There is a Pfam entry for this protein: Secretogranin_V (PF05281).
Ubiquitin-conjugating enzyme E2 G2 is a protein that in humans is encoded by the UBE2G2 gene.
U2 small nuclear ribonucleoprotein B is a protein that in humans is encoded by the SNRPB2 gene.
Endoplasmic reticulum protein 29 (ERp29) is a chaperone protein that in humans is encoded by the ERP29 gene.
PNGase also known as N-glycanase 1 or peptide-N(4)-(N-acetyl-beta-glucosaminyl)asparagine amidase is an enzyme that in humans is encoded by the NGLY1 gene. PNGase is a de-N-glycosylating enzyme that removes N-linked or asparagine-linked glycans (N-glycans) from glycoproteins. More specifically, NGLY1 catalyzes the hydrolysis of the amide bond between the innermost N-acetylglucosamine (GlcNAc) and an Asn residue on an N-glycoprotein, generating a de-N-glycosylated protein, in which the N-glycoylated Asn residue is converted to asp, and a 1-amino-GlcNAc-containing free oligosaccharide. Ammonia is then spontaneously released from the 1-amino GlcNAc at physiological pH (<8), giving rise to a free oligosaccharide with an N,N’-diacetylchitobiose structure at the reducing end.
Reticulon-2 is a protein that in humans is encoded by the RTN2 gene.
Reticulons are a group of evolutionary conservative proteins residing predominantly in endoplasmic reticulum, primarily playing a role in promoting membrane curvature. In addition, reticulons may play a role in nuclear pore complex formation, vesicle formation, and other processes yet to be defined. They have also been linked to oligodendrocyte roles in inhibition of neurite outgrowth. Some studies link RTNs with Alzheimer's disease and amyotrophic lateral sclerosis.
Transmembrane protein 33 is a protein that in humans, is encoded by the TMEM33 gene, also known as SHINC3. Another name for the TMEM33 protein is DB83.
Collagen beta(1-O)galactosyltransferase 1 is a protein that in humans is encoded by the COLGALT1 gene.
