Systematic name YDR057W
Gene name YOS9
Aliases
Feature type ORF, Verified
Coordinates Chr IV:565925..567553


Description of YDR057W: Lectin; soluble lumenal ER protein; member of the OS-9 protein family; similar to mannose-6-phosphate receptors (MPRs); serves as a receptor that recognizes misfolded N-glycosylated proteins and participates in their targeting to ERAD[1][2][3][4]

Protein Details

Protein Function/Process

The ER lumenal protein Yos9p is required for both release of DHFR and degradation of multiple ERAD substrates. Yos9p forms a complex with substrates and has a sugar binding pocket that is essential for its ERAD function. Nonetheless, substrate recognition persists even when the sugar binding site is mutated or CPY* is unglycosylated. These and other considerations suggest that Yos9p plays a critical role in the bipartite recognition of terminally misfolded glycoproteins. [2] [5]
