General annotation (Comments)

Function	Required for synthesis of full length mannan chains. Ref.3 The M-Pol II 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. Ref.3
Subunit structure	Component of the M-Pol II complex composed of ANP1, MNN9, MNN10, MNN11 and HOC1. Ref.3 Ref.2
Subcellular location	Golgi apparatus › cis-Golgi network membrane; Single-pass type II membrane protein.
Miscellaneous	Present with 3480 molecules/cell in log phase SD medium. Ref.4
Sequence similarities	Belongs to the glycosyltransferase 34 family.
