  • Interaction with the membrane-anchored protein CHIC2 constrains the ubiquitin ligase activity of CHIP

    • Tác giả : Callahan, M.D. (2023)

  • Maintenance of cellular health requires the proper regulation of E3 ubiquitin ligases. The E3 ligase CHIP is canonically regulated by its interactions with the molecular chaperones Hsp70 and Hsp90, which focus CHIP’s ubiquitination activity on misfolded proteins. Here, we report a chaperone-independent interaction of CHIP with the membrane-anchored protein CHIC2, which strongly attenuates CHIP’s ligase activity. We show that CHIC2 outcompetes abundant, cytosolic chaperones&...
