General annotation (Comments)

Function	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.
Subunit structure	Component of the M-Pol I complex which contains MNN9 and VAN1. Ref.4 Ref.5
Subcellular location	Endoplasmic reticulum membrane; Single-pass type II membrane protein. Golgi apparatus membrane; Single-pass type II membrane protein. Note: Cis-Golgi. Recycles between endoplasmic reticulum and Golgi. Ref.4 Ref.5 Ref.6
Post-translational modification	Glycosylated. Ref.5
Miscellaneous	Present with 4750 molecules/cell in log phase SD medium. Ref.8
Sequence similarities	Belongs to the ANP1/MMN9/VAN1 family.
