Automated description from the Alliance of Genome Resources (Release 5.2.2)
Enables uracil DNA N-glycosylase activity. Acts upstream of or within isotype switching and somatic hypermutation of immunoglobulin genes. Located in mitochondrion and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; lung; and olfactory epithelium. Human ortholog(s) of this gene implicated in dysgammaglobulinemia and immunodeficiency with hyper IgM type 5. Orthologous to human UNG (uracil DNA glycosylase).
