Predicted to enable K63-linked polyubiquitin modification-dependent protein binding activity; pentosyltransferase activity; and transcription corepressor activity. Predicted to be involved in several processes, including negative regulation of NF-kappaB transcription factor activity; negative regulation of macromolecule metabolic process; and protein ADP-ribosylation. Predicted to act upstream of or within DNA repair. Predicted to be located in Golgi apparatus; cytosol; and nucleolus. Predicted to be active in cytoplasm and nucleus. Orthologous to human PARP10 (poly(ADP-ribose) polymerase family member 10). [provided by Alliance of Genome Resources, Apr 2022]
