  • What Are Ubiquitin Conjugating Partners Of CHIP?

    Ubiquitin-conjugating partners of CHIP: In section 3, after " fate of substrates": E2’s are the family of enzymes, having highly conserved ubiquitin conjugating domains. These enzymes, in combination with E3s, play an important role in determining the fate of substrate proteins by selecting a lysine residue on which ubiquitin moiety must be added. In section 3, after Murata, et al. 2003: An in vitro study has shown that CHIP, with the aid of UbcH5 and UbcH6, two other E2s, can efficiently…
