The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 76 kDa (predicted molecular weight: 76 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use at an assay dependent concentration.
ELISA titre using peptide based assay 1/312500.
関連性RNF139 is a multi-membrane spanning protein E3 ubiquitin ligase which is mutated in clear-cell renal carcinomas. It contains a sterol-sensing domain and a RING-H2 motif essential for ubiquitin ligase activity. It is a potential tumor suppressor for renal cell carcinoma. Human kidney cells are growth inhibited by RNF139. Inhibition is manifested by G2/M arrest and is dependent upon the ubiquitin ligase activity of the RING domain. Expression of RNF139 represses genes involved in cholesterol and fatty acid biosynthesis that are transcriptionally regulated by the sterol response element binding proteins (SREBPs). RNF139 modulation of SREBP activity comprises a novel regulatory link between growth control and the cholesterol/lipid homeostasis pathway.
