Background: SUMO-GFP Protease Substrate

SUMO-GFP Protease Substrate is a recombinant protein that contains SUMO fused to GFP that can be used as a positive control in an SDS-PAGE gel-shift assay to detect cleavage activity by Recombinant SUMO Protease ULP1 (Catalog # http://www.rndsystems.com/product_results.aspx?k=11697-SO">11697-SO) and Recombinant Human His6-SENP1 Catalytic Domain Protein
(Catalog # http://www.rndsystems.com/product_results.aspx?k=E-700">E-700). SUMO is a member of the small ubiquitin-like modifier (SUMO) family. In the cell, the SUMO protein is modified and covalently conjugated to other proteins in the cell via an isopeptide bond formed between its carboxyl-terminal glycine residues and the lysine of the protein substrate in a similar parallel mechanism of ubiquitination that regulates cellular processes such as DNA replication and repair, nuclear transport, signal transduction, and regulation of transcription (1-3). Use of SUMO fusions as a technology has been used to enhance protein expression, solubility, and purification in prokaryotes for a diverse population of protein targets and unlike other common fusion partners SUMO can serve as a chaperone for correct folding (4).  SUMO is cleaved at its c-terminus to a mature form after a glycine-glycine pair by a family of sentrin/SUMO-specific proteases (SENPs) in humans and ubiquitin-like protein specific proteases (Ulps) in yeast to regulate the reversible process of sumoylation (3). In a fusion application, the cleavage of SUMO allows for successful recombinant protein production with a native N-terminal sequence providing a distinct advantage over other fusion cleavage models used in recombinant protein production in both academic research and industrial biotechnology (4‑10).
