Protein

Mannan polymerase I complex VAN1 subunit

Gene

VAN1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Involved in regulation of the phosphorylation of a number of proteins, some of which appear to be important in cell growth control.
The M-Pol I complex possesses alpha-1,6-mannosyltransferase activity and is probably involved in the elongation of the mannan backbone of N-linked glycans on cell wall and periplasmic proteins.

Miscellaneous

Present with 4750 molecules/cell in log phase SD medium.1 Publication
