Abstract: Broad-complex, tramtrack, and bric-à-brac domain (BTB) and CNC homolog 1 (BACH1) is a key regulator of the cellular oxidative stress response and an oncogene that undergoes tight post-translational ...Broad-complex, tramtrack, and bric-à-brac domain (BTB) and CNC homolog 1 (BACH1) is a key regulator of the cellular oxidative stress response and an oncogene that undergoes tight post-translational control by two distinct F-box ubiquitin ligases, SCF and SCF. However, how both ligases recognize BACH1 under oxidative stress is unclear. In our study, we elucidate the mechanism by which FBXO22 recognizes a quaternary degron in a domain-swapped β-sheet of the BACH1 BTB dimer. Cancer-associated mutations and cysteine modifications destabilize the degron and impair FBXO22 binding but simultaneously expose an otherwise shielded degron in the dimer interface, allowing FBXL17 to recognize BACH1 as a monomer. These findings shed light on a ligase switch mechanism that enables post-translational regulation of BACH1 by complementary ligases depending on the stability of its BTB domain. Our results provide mechanistic insights into the oxidative stress response and may spur therapeutic approaches for targeting oxidative stress-related disorders and cancer.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
