Abstract
Ovarian tumor domain-containing protein 1 (OTUD1), an OTU-family deubiquitinating enzyme, has been reported to be involved in cancer progression through the regulation of p53 and SMAD7. However, the precise pathophysiological functions of OTUD1 remain elusive. Here, we report the establishment of OTUD1-specific monoclonal antibodies (mAbs), using the rat medial iliac lymph node method. The generated antibodies recognize the N-terminal portion (aa. 1-290) of human and mouse OTUD1 proteins. In addition, immunofluorescent staining and subcellular fractionation analyses using these antibodies indicated that OTUD1 is predominantly localized in the cytosol. Thus, these mAbs can be further used to elucidate cellular functions of OTUD1 and its involvement in processes such as cancer progression.
