UniProtKB - Q5R4Q3 (SEC62_PONAB)
Protein
Translocation protein SEC62
Gene
SEC62
Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Functioni
Mediates post-translational transport of precursor polypeptides across endoplasmic reticulum (ER). Proposed to act as a targeting receptor for small presecretory proteins containing short and apolar signal peptides. Targets and properly positions newly synthesized presecretory proteins into the SEC61 channel-forming translocon complex, triggering channel opening for polypeptide translocation to the ER lumen.By similarity
