Ubiquitin Mutant V70A

1 mg

Ubiquitin has a distinct and functionally important hydrophobic patch whose surface is defined by three residues including Leu8, Ile44 and Val70. These residues are solvent accessible in ubiquitin chains and are critical for poly-ubiquitin chain interaction and recognition by the 26S proteasome and subsequent target degradation. These hydrophobic residues interact directly with various factors that bind to Ub and/or mediate Ub-Ub interactions in ubiquitin chains that may influence orientation and recognition. Ubiquitin V70A can form an E1-catalyzed active thioester at the
C-terminus allowing the molecule to be transferred to the lysines of substrate proteins.
