Design principles of Cdr2 node patterns in fission yeast cells

H. E. Opalko, S. Geng, A. R. Hall, D. Vavylonis, J. B. Moseley

The paper investigates how Cdr2 nodes form and position in fission yeast cells using experimental and modeling approaches, finding that tip inhibition and cortical anchoring are sufficient for node assembly without a nucleus.

Arf6 anchors Cdr2 nodes at the cell cortex to control cell size at division

H. E. Opalko, K. E. Miller, H.-S. Kim, C. A. Vargas-Garcia, A. Singh, M.-C. Keogh, J. B. Moseley

This study identifies Arf6 as an anchor for Cdr2 nodes at the cell cortex, essential for surface area-based size control in fission yeast.

Fission yeast Pak1 phosphorylates anillin-like Mid1 for spatial control of cytokinesis

J. O. Magliozzi, J. Sears, L. Cressey, M. Brady, H. E. Opalko, A. N. Kettenbach, J. B. Moseley

This study identifies Pak1 as a kinase that phosphorylates Mid1 to regulate cytokinesis in fission yeast by controlling CAR assembly and division plane positioning.

A mechanism for how Cdr1/Nim1 kinase promotes mitotic entry by inhibiting Wee1

H. E. Opalko, I. Nasa, A. N. Kettenbach, J. B. Moseley

This study identifies how Cdr1/Nim1 kinase inhibits Wee1 to promote mitotic entry by phosphorylating specific serine residues in yeast.

Stable Pom1 clusters form a glucose-modulated concentration gradient that regulates mitotic entry

C. A. H. Allard, H. E. Opalko, J. B. Moseley

The paper shows Pom1 forms stable clusters that create a glucose-modulated gradient regulating mitotic entry in fission yeast.

Cell size-dependent regulation of Wee1 localization by Cdr2 cortical nodes

C. A. H. Allard, H. E. Opalko, K.-W. Liu, U. Medoh, J. B. Moseley

This study shows how cell growth inhibits fission yeast Wee1 through dynamic bursts of its localization to cortical nodes containing inhibitory kinases.
