Signal peptidase subunit 3.

Signal peptidase complex catalytic subunit SEC11; Catalytic component of the signal peptidase complex (SPC), which catalyzes the cleavage of N-terminal signal sequences of proteins targeted to the endoplasmic reticulum. Signal peptide cleavage occurs during the translocation (cotranslationally or post-translationally) through the translocon pore into the endoplasmic reticulum (By similarity).

Mitochondrial inner membrane protease subunit.

Catalytic subunit of the mitochondrial inner membrane peptidase complex.

Dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit OST2; Subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol- pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. N-glycosylation occurs cotranslationally and the complex associates with the Sec61 complex at the channel-forming translocon complex that mediates protein translocation across the [...]

Protein transport protein Sec61 subunit beta; Necessary for protein translocation in the endoplasmic reticulum.

Uncharacterized protein.

Subunit of the signal recognition particle (SRP), involved in protein targeting to the ER.

Signal recognition particle 54 kDa protein; Binds to the signal sequence of presecretory protein when they emerge from the ribosomes and transfers them to TRAM (translocating chain-associating membrane protein). Belongs to the GTP-binding SRP family. SRP54 subfamily.
