Predicted to enable several functions, including hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in linear amides; protein-propionyllysine depropionylase activity; and transcription corepressor activity. Predicted to be involved in several processes, including cellular macromolecule biosynthetic process; protein deacylation; and regulation of nucleobase-containing compound metabolic process. Predicted to be located in nuclear speck; nucleolus organizer region; and site of double-strand break. Predicted to be active in nucleus. Orthologous to human SIRT7 (sirtuin 7).
