Summary: This gene encodes a type I integral membrane protein found only in the rough endoplasmic reticulum. The encoded protein is part of an N-oligosaccharyl transferase complex that links high mannose oligosaccharides to asparagine residues found in the Asn-X-Ser/Thr consensus motif of nascent polypeptide chains. This protein forms part of the regulatory subunit of the 26S proteasome and may mediate binding of ubiquitin-like domains to this proteasome. [provided by RefSeq, Jul 2008]

Polyubiquitin and ubiquitin-like signals share common recognition sites on proteasomal subunit Rpn1.
Title: Polyubiquitin and ubiquitin-like signals share common recognition sites on proteasomal subunit Rpn1.
Study provides evidence that Rpn1-Ser361 is a prevalent phosphosite that is required for proper assembly and activity of the 26S proteasome and identified multiple kinases, including PIM1/2/3, that can phosphorylate Rpn1-S361 and have demonstrated that UBLCP1 is a physiologically relevant phosphatase of this site. Blocking phosphorylation of Rpn1-S361 leads to slowed proliferation and mitochondrial dysfunction.
Title: Reversible phosphorylation of Rpn1 regulates 26S proteasome assembly and function.
These results clearly demonstrate that the association of malectin with ribophorin I is required to capture misfolded alpha1-antitrypsin and direct them to the degradation pathway.
Title: Association of malectin with ribophorin I is crucial for attenuation of misfolded glycoprotein secretion.
Data indicate that malectin functions by forming a complex with ribophorin I.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
