Enables ubiquitin conjugating enzyme activity and ubiquitin protein ligase binding activity. Acts upstream of or within blastocyst hatching; maternal process involved in female pregnancy; and protein ubiquitination. Located in XY body and chromatin. Is expressed in several structures, including alimentary system; brain; female reproductive system; integumental system; and respiratory system. Human ortholog(s) of this gene implicated in syndromic X-linked intellectual disability Nascimento type. Orthologous to human UBE2A (ubiquitin conjugating enzyme E2 A).
