Specificity
Rabbit anti RPAP3 antibody recognizes RNA polymerase II-associated protein 3 (RPAP3), also known as HSpagh and Tah1. It is a component of the R2TP/PFDL complex (Cloutier et al. 2009) and provides a flexible scaffold for allowing the abundant molecular chaperone HSP90 to interact with other proteins including RNA Pol II, TOR and SMG1, allowing the assembly of important cellular complexes (Martino et al. 2018). It has been suggested that RPAP3 can modulate UV-induced DNA damage (Ni et al. 2009). RPAP3 appears to bind to NEMO, inhibiting the NF-kappaB signaling pathway and enhancing cytotoxicity of the chemotherapeutic agent doxorubicin (Shimada et al. 2011).
