Structural and biochemical basis of FANCI-FANCD2 interdependent ubiquitination

K. Lemonidis, M. L. Rennie, C. Arkinson, V. K. Chaugule, M. Clarke, J. Streetley, H. Walden

This paper presents a cryo-EM structure of the FANCI-FANCD2 complex bound to DNA, showing how ubiquitination dynamics regulate its function in DNA repair.

Cryo-EM reveals a mechanism of USP1 inhibition through a cryptic binding site

M. L. Rennie, C. Arkinson, V. K. Chaugule, H. Walden

The paper uses cryo-EM to reveal how ML323 inhibits USP1 by displacing part of its hydrophobic core, causing conformational changes that disrupt the active site.

Differential functions of FANCI and FANCD2 ubiquitination stabilize ID2 complex on DNA

H. Walden, M. L. Rennie, K. Lemonidis, C. Arkinson, V. K. Chaugule, M. Clarke, J. Streetley, L. Spagnolo

This study identifies how ubiquitination of FANCI and FANCD2 stabilizes the ID2 complex on DNA, enhancing its affinity for double-stranded DNA and protecting ubiquitin from deubiquitination.

Specificity for deubiquitination of monoubiquitinated FANCD2 is driven by the N-terminus of USP1

C. Arkinson, V. K. Chaugule, R. Toth, H. Walden

This study identifies the N-terminus of USP1 as critical for its specificity in deubiquitinating FANCD2, but not PCNA or FANCI.

Allosteric network in Ube2T drives specificity for RING E3 catalysed ubiquitin signals.

V. K. Chaugule, C. Arkinson, R. Toth, H. Walden

The paper identifies an allosteric network in Ube2T that enhances FANCD2 ubiquitination while maintaining specificity, and reveals similar networks in other E2s.
