Genes affected

TNKS2 (HGNC:15677): (tankyrase 2) Enables NAD+ ADP-ribosyltransferase activity; enzyme binding activity; and protein ADP-ribosylase activity. Involved in several processes, including protein ADP-ribosylation; protein localization to chromosome, telomeric region; and regulation of telomere maintenance. Located in nuclear envelope; pericentriolar material; and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
