I knew there are ... Cleavage of PARP, by enzymes such as caspases or cathepsins, typically inactivates PARP. The size of the cleavage fragments can give insight into which enzyme was responsible for the cleavage and can be useful in determining which cell death pathway has been activated. See more Poly (ADP-ribose) polymerase (PARP) is a family of proteins involved in a number of cellular processes such as DNA repair, genomic stability, and programmed cell death. See more The PARP family comprises 17 members (10 putative). They vary greatly in structure and function within the cell. • PARP1, PARP2, VPARP (PARP4), Tankyrase-1 and -2 (PARP-5a or TNKS, and PARP-5b or TNKS2) have a confirmed PARP activity. See more The main role of PARP (found in the cell nucleus) is to detect and initiate an immediate cellular response to metabolic, chemical, or radiation-induced single-strand DNA breaks (SSB) by signaling the enzymatic machinery involved in the SSB repair See more PARP is inactivated by caspase cleavage. It is believed that normal inactivation occurs in systems where DNA damage is extensive. In these … See more PARP is composed of four domains of interest: a DNA-binding domain, a caspase-cleaved domain (see below), an auto-modification domain, and a catalytic domain. The DNA-binding domain is composed of two zinc finger motifs. In the presence of … See more The catalytic domain is responsible for Poly (ADP-ribose) polymerization. This domain has a highly conserved motif that is common to all members of the PARP family. PAR … See more Roles of poly(ADP-ribosyl)ation in plant responses to DNA damage, infection, and other stresses have been studied.
