ubc-9 encodes an E2 ubiquitin-conjugating enzyme orthologous to Saccharomyces cerevisiae Ubc9p, which mediates the covalent attachment of the small ubiquitin-related modifier (SUMO) to various substrates including Ran-GAP1 and p53; UBC-9 activity is required for several developmental processes including embryogenesis, larval development, vulval development, posterior morphogenesis, and the DNA damage response (both DNA repair and DNA damage checkpoint function); UBC-9 interacts with LIN-1, an ETS-domain-containing transcription factor that negatively regulates vulval development, and with RAD-51, the C. elegans RecA homolog that is required for DNA repair.
Enables RNA polymerase II-specific DNA-binding transcription factor binding activity; SAM domain binding activity; and SUMO conjugating enzyme activity. Involved in several processes, including negative regulation of transcription by RNA polymerase II; pharyngeal muscle development; and protein sumoylation. Predicted to be located in nucleus. Expressed in body wall musculature; coelomocyte; pharynx; tail; and in male. Human ortholog(s) of this gene implicated in dilated cardiomyopathy; ovarian cancer; and urinary bladder cancer. Is an ortholog of human UBE2I (ubiquitin conjugating enzyme E2 I).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
