Enables alcohol binding activity; dolichyl-phosphate beta-D-mannosyltransferase activity; and mannose binding activity. Involved in GDP-mannose metabolic process and dolichol metabolic process. Located in intracellular membrane-bounded organelle. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation Ie. Orthologous to human DPM1 (dolichyl-phosphate mannosyltransferase subunit 1, catalytic). [provided by Alliance of Genome Resources, Apr 2022]
