RNA recognition motif (RRM) found in RAD52 motif-containing protein 1 (RDM1) and similar proteins This subfamily corresponds to the RRM of RDM1, also termed RAD52 homolog B, a novel factor involved in the cellular response to the anti-cancer drug cisplatin in vertebrates. RDM1 contains a small RD motif that shares with the recombination and repair protein RAD52, and an RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain). The RD motif is responsible for the acidic pH-dependent DNA-binding properties of RDM1. It interacts with ss- and dsDNA, and may act as a DNA-damage recognition factor by recognizing the distortions of the double helix caused by cisplatin-DNA adducts in vitro. In addition, due to the presence of RRM, RDM1 can bind to RNA as well as DNA. |
