WebPARP1 is zinc-dependent DNA binding protein that recognizes DNA strand breaks and is presumed to play a role in DNA repair. It is involved in the base excision repair (BER) pathway, by catalyzing the poly (ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. WebMar 13, 2024 · We confirmed by endogenous coimmunoprecipitation that Smurf2 is a novel protein that interacts with PARP1 (Figure 3A,B), We overexpressed Flag-Smurf2 and Myc-PARP1 for 48 hours in 293T cells, through the exogenous coimmunoprecipitation to verify the exogenous interaction between Flag-Smurf2 and Myc-PARP1 (Figure 3C). WebHowever, the biological and clinical significance of PARP1 expression in BC and its role in DNA-damage response (DDR) remain to be defined. We investigated the expression of PARP1 expression, cleaved (PARP1c) and non-cleaved (PAR1nc) forms, in a large and well-characterised cohort of clinically annotated stage I-III operable BCs (n = 1,269) and ... food and glory recetas
