Enables ubiquitin conjugating enzyme activity and ubiquitin protein ligase binding activity. Involved in positive regulation of canonical Wnt signaling pathway. Acts upstream of or within several processes, including chromosome organization; positive regulation of reciprocal meiotic recombination; and sperm axoneme assembly. Located in XY body and chromatin. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and immune system. Orthologous to human UBE2B (ubiquitin conjugating enzyme E2 B).
