Gene name ALG13
Aliases
Feature type ORF, Verified
Coordinates Chr VII:411555..412163
Primary SGDID S000003015


Description of YGL047W: Catalytic component of UDP-GlcNAc transferase, required for the second step of dolichyl-linked oligosaccharide synthesis; anchored to the ER membrane via interaction with Alg14p; similar to bacterial and human glycosyltransferases[1][2][3]

Cytosolic Alg13 not bound to Alg14 at the ER membrane is very short-lived. Ubiquitin-independent proteasomal degradation is mediated by an autonomous C-terminal domain. Addition of C-terminal epitope tags interfere with Alg13 degradation.
