MACROD2 (MACRO Domain Containing 2): MACROD2 is a gene involved in the ADP-ribosylation process, a post-translational modification important for DNA repair, gene expression, and signal transduction. It plays a role in regulating genomic stability and cellular responses to stress. Alterations in MACROD2 have been linked to various cancers and neurological disorders, highlighting its significance in DNA repair and stress response mechanisms.
