The O-Fucosyltransferase SPINDLY Attenuates Auxin-Induced Fruit Growth by Inhibiting ARF6 and ARF8 binding to Coactivator Mediator Complex in Arabidopsis

Y. Wang, S. Kelley, R. Zentella, J. Hu, H. Wei, L. Wang, J. Shabanowitz, D. Hunt, T.-p. Sun

This study shows that SPINDLY-mediated O-fucosylation of ARF6 and ARF8 inhibits their interaction with the coactivator Mediator complex, reducing fruit growth in Arabidopsis.

Phosphorylation Promotes DELLA Activity by Enhancing Its Binding to Histone H2A at Target Chromatin in Arabidopsis

X. Huang, R. Zentella, J. Park, L. Reser, D. Bai, M. Ross, J. Shabanowitz, D. Hunt, T.-p. Sun

This study identifies phosphorylation as a new regulatory mechanism for DELLA activity by enhancing its binding to histone H2A at target chromatin in Arabidopsis.

Glutamylation of Npm2 and Nap1 acidic disordered regions increases DNA charge mimicry to enhance chaperone efficiency

B. M. Lorton, C. Warren, H. Ilyas, P. Nandigrami, S. Hegde, S. Cahill, S. M. Lehman, J. Shabanowitz, D. Hunt, A. Fiser, D. Cowburn, D. Shechter

The paper shows that glutamylation of acidic IDRs in Npm2 and Nap1 enhances their DNA mimicry function, improving histone chaperone efficiency in nucleosome assembly.

OGT (O-GlcNAc Transferase) selectively modifies multiple residues unique to lamin A

D. N. Simon, A. Wriston, Q. Fan, J. Shabanowitz, A. Florwick, T. Dharmaraj, S. B. Peterson, Y. Gruenbaum, C. R. Carlson, L. M. Gronning-Wang, D. F. Hunt, K. L. Wilson

This study identifies O-GlcNAc modifications unique to lamin A, showing OGT modifies specific residues in lamin A tails but not lamin B1, lamin C, or progerin.

Canonical and cross-reactive binding of NK cell inhibitory receptors to HLA-C allotypes is dictated by peptides bound to HLA-C

M. J. W. Sim, S. A. Malaker, A. Khan, J. M. Stowell, J. Shabanowitz, M. E. Peterson, S. Rajagopalan, D. F. Hunt, D. M. Altmann, E. O. Long, R. J. Boyton

This study shows that HLA-C bound peptides influence KIR binding specificity, with KIR2DL1 showing broader peptide tolerance than KIR2DL2/3, and cross-reactive binding being highly peptide selective.
