Description

UbiQ-030 (K13 Ub-PTEN(5-21)-FP) is a class II fluorescence polarization DUB activity assay reagent based on the peptide sequence 5 – 21 of PTEN, a tumor suppressor phosphatase which is monoubiquitinated on Lys13 and Lys289. Monoubiquitination of these sites is important for regulation of PTEN mediated tumor suppression and its nuclear import. The peptide is modified on the N-terminus with a 5-carboxytetramethylrhodamine and conjugated at Lys13 to Ub via a native isopeptide bond. See reference 4 (open access) in the product sheet for full experimental and analytical details.
