A proteome-wide dependency map of protein interaction motifs

Sara M. Ambjørn, Bob Meeusen, Johanna Kliche…·Jakob Nilsson

The paper systematically assesses the function of short linear motifs (SLiMs) by mutating and screening them in human cells, identifying essential SLiMs for cell proliferation and uncovering novel classes and binding partners.

A functional map of phosphoprotein phosphatase regulation identifies an evolutionary conserved reductase for the catalytic metal ions

Bob Meeusen, Sara M. Ambjørn, Jiri Veis…·Jakob Nilsson

The paper identifies CYB5R4 as an evolutionarily conserved reductase that activates PP4 and PP6 by reducing their catalytic metal ions, essential for cell viability under oxidative stress.
