This study shows that Lac1-dependent ceramide synthesis is essential for proper septum assembly and cell separation in fission yeast.

This study shows that specific ceramide structural features, particularly acyl chain length and sphingoid base hydroxylation, differentially regulate nutrient sensing, TORC2 signaling, and cell size control in yeast.

The paper investigates the role of casein kinase 1 homologs Yck1 and Yck2 in regulating the TORC2 signaling network in budding yeast, finding they strongly influence multiple network components.

The paper challenges a model proposing that protein synthesis increases in pre-Start G1, finding that Whi5 concentration remains constant and Cln3 increase is not due to synthesis.
