DESCRIPTION

Also known as UBP25_HUMAN, USP25, USP21. Deubiquitinating enzyme that hydrolyzes ubiquitin moieties conjugated to substrates and thus, functions to process newly synthesized Ubiquitin, to recycle ubiquitin molecules or to edit polyubiquitin chains and prevents proteasomal degradation of substrates. Hydrolyzes both 'Lys-48'- and 'Lys-63'-linked tetraubiquitin chains., The muscle-specific isoform (USP25m) may have a role in the regulation of muscular differentiation and function. Homodimer or oligomer. Interacts with ACTA1 (via its C-terminus); the interaction occurs for all isoforms but is strongest for isoform USP25m in muscle differentiating cells. Interacts (isoform USP25m only) with MYBPC1; the interaction prevents proteasomal degradation of MYBPC1. Interacts (isoform USP25m only) with FLNC (via filament repeats 17-18, 20-21 and 24). Interacts with GAPDH. Interacts with SUMO3; the interaction sumoylates efficiently USP25. Interacts with SUMO2; the interaction sumoylates efficiently USP25. Interacts with SUMO1; the interaction only weakly sumoylates USP25. Interacts with SYK; phosphorylates USP25 and regulates USP25 intracellular levels.
