Protein

Protein PBN1

Gene
PBN1, CaO19.10951, CaO19.3447
Organism
Candida albicans (strain SC5314 / ATCC MYA-2876) (Yeast)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Required for proper folding and/or the stability of a subset of proteins in the endoplasmic reticulum. Component of glycosylphosphatidylinositol-mannosyltransferase 1 which transfers the first of the 4 mannoses in the GPI-anchor precursors during GPI-anchor biosynthesis. Probably acts by stabilizing the mannosyltransferase GPI14 By similarity.
