Small ubiquitin-related modifier (SUMO)-specific proteases: profiling the specificities and activities of human SENPs.
SENPs are proteases that participate in the regulation of SUMOylation by generating mature small ubiquitin-related modifiers (SUMO) for protein conjugation (endopeptidase activity) and removing conjugated SUMO from targets (isopeptidase activity). Using purified recombinant catalytic domains of 6 of the 7 human SENPs, we demonstrate the specificity of their respective activities on SUMO-1, -2, ...
متن کامل[SUMO-specific protease 1 and cancer].
Post-translational modifiers of the small ubiquitin-like modifier protein (SUMO) family have emerged as key regulators of protein function and localization. SUMO modification is a dynamic process, catalyzed by SUMO-specific E1, E2, and E3 enzymes and reversed by a family of SUMO-specific proteases (SENPs). Although six human SENPs have been identified, each with different cellular locations and...
متن کاملIdentification and Developmental Expression of Xenopus laevis SUMO Proteases
SUMO proteins are small ubiquitin-related modifiers. All SUMOs are synthesized as propeptides that are post-translationally cleaved prior to conjugation. After processing, SUMOs become covalently conjugated to cellular targets through a pathway that is similar to ubiquitination. Ubiquitin like protein proteases/Sentrin specific proteases (Ulp/SENPs) mediate both processing and deconjugation of ...
متن کاملSmall ubiquitin-like modifier protein-specific protease 1 and prostate cancer.
Small ubiquitin-like modifier protein (SUMO) modification is a highly dynamic process, catalyzed by SUMO-specific activating (E1), conjugating (E2) and ligating (E3) enzymes, and reversed by a family of SUMO-specific proteases (SENPs). There are six members of the human SENP family, and each SENP has different cellular locations and substrate specificities. However, the precise roles of SENPs i...
متن کاملMapping residues of SUMO precursors essential in differential maturation by SUMO-specific protease, SENP1.
SUMO (small ubiquitin-related modifier) is a member of the ubiquitin-like protein family that regulates cellular function of a variety of target proteins. SUMO proteins are expressed as their precursor forms. Cleavage of the residues after the 'GG' region of these precursors by SUMO-specific proteases in maturation is a prerequisite for subsequent sumoylation. To understand further this proteol...
