Recombinant Human Protein transport protein Sec61 subunit beta (SEC61B), Truncated

Uniprot Id

P60468

Target Species

Human

Target Name

SEC61B

Target Full Name

Protein transport protein Sec61 subunit beta

Target Function

Component of SEC61 channel-forming translocon complex that mediates transport of signal peptide-containing precursor polypeptides across the endoplasmic reticulum (ER). Component of a ribosome-associated ER translocon complex involved in multi-pass membrane protein transport into the ER membrane and biogenesis. The SEC61 channel cooperates with the translocating protein TRAM1 to import nascent proteins into the ER. Required for PKD1/Polycystin-1 biogenesis.

Target Subcellular Location

Endoplasmic reticulum membrane; Single-pass membrane protein.

Target Protein Families

SEC61-beta family

Target Synonyms

SEC61B; Protein transport protein Sec61 subunit beta

Target Background

The Sec61 complex is the central component of the protein translocation apparatus of the endoplasmic reticulum (ER) membrane. Oligomers of the Sec61 complex form a transmembrane channel where proteins are translocated across and integrated into the ER membrane. This complex consists of three membrane proteins- alpha, beta, and gamma. This gene encodes the beta-subunit protein. The Sec61 subunits are also observed in the post-ER compartment, suggesting that these proteins can escape the ER and recycle back. There is evidence for multiple polyadenylated sites for this transcript.
