What's a GeneRIF?

The N- and C-termini of Alg14 coordinate recruitment of catalytic Alg7 and Alg13 to the endoplasmic reticulum membrane for initiating lipid-linked oligosaccharide biosynthesis.
Title: Alg14 organizes the formation of a multiglycosyltransferase complex involved in initiation of lipid-linked oligosaccharide biosynthesis.
Alg13 and Alg14 interaction at the C terminus mediates formation of the active UDP-N-acetylglucosamine transferase complex
Title: Interaction between the C termini of Alg13 and Alg14 mediates formation of the active UDP-N-acetylglucosamine transferase complex.
These data lead to the model that proteasomal degradation of excess unassembled Alg13p is an important quality control mechanism that ensures proper protein complex assembly and correct N-linked glycosylation.
Title: Alg13p, the catalytic subunit of the endoplasmic reticulum UDP-GlcNAc glycosyltransferase, is a target for proteasomal degradation.
Titration of Alg13 with both UDP-GlcNAc, the native glycosyl donor, and a paramagnetic mimic, UDP-TEMPO, shows that the interaction of Alg13 with the sugar donor is primarily through the residues in the C-terminal half of the protein.
Title: Solution structure of Alg13: the sugar donor subunit of a yeast N-acetylglucosamine transferase.
Alg13-Alg14 UDP-GlcNAc transferase represents an unprecedented example of a bipartite glycosyltransferase that evolved by both fission and fusion
Title: Membrane topology of the Alg14 endoplasmic reticulum UDP-GlcNAc transferase subunit.
Alg13p associates with Alg14p to a complex forming the active transferase catalyzing the biosynthesis of GlcNAc(2)-PP-Dol
Title: Biosynthesis of lipid-linked oligosaccharides in Saccharomyces cerevisiae: Alg13p and Alg14p form a complex required for the formation of GlcNAc(2)-PP-dolichol.
