NCIt related terms : PARP; poly (ADP-ribose) polymerase; poly(ADP-ribose) polymerase-1;
NCIt definition : Poly [ADP-ribose] polymerase 1 (1013aa, 113 kDa) is encoded by the human PARP1 gene.
This protein is involved in poly ADP-ribosylation and in the regulation of various
cellular processes such as differentiation, proliferation, tumor transformation, and
recovery from DNA damage.;
Alternative definition : NCI-GLOSS: An enzyme involved in many functions of the cell, including the repair
of DNA damage. DNA damage may be caused by normal cell actions, UV light, some anticancer
drugs, and radiation used to treat cancer. Inhibitors of PARP-1 are being studied
in the treatment of cancer.;
NCIt note : Poly [ADP ribose] polymerase 1 is a cytosolic protein, and when activated is cleaved
into two fragments of 89kd and 24kd.;
