Predicted to enable several functions, including alpha-1,3-mannosyltransferase activity; calcium-dependent protein binding activity; and protein heterodimerization activity. Predicted to be involved in dolichol-linked oligosaccharide biosynthetic process; protein glycosylation in endoplasmic reticulum; and response to calcium ion. Predicted to be located in several cellular components, including actin cytoskeleton; cytosol; and perinuclear region of cytoplasm. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation Ii and congenital myasthenic syndrome 14. Orthologous to human ALG2 (ALG2 alpha-1,3/1,6-mannosyltransferase).
