Summaries for SEC61B Gene

Entrez Gene Summary for SEC61B Gene

  • 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for SEC61B Gene

SEC61B (Sec61 Beta Subunit) is a Protein Coding gene. Among its related pathways are Class I MHC mediated antigen processing and presentation and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include epidermal growth factor binding.
