CHS3

CAL1, CSD2, DIT101, KTI2, chitin synthase CHS3, L000000331, YBR023C
Chitin synthase III; catalyzes the transfer of N-acetylglucosamine (GlcNAc) to chitin; required for synthesis of the majority of cell wall chitin, the chitin ring during bud emergence, and spore wall chitosan; contains overlapping di-leucine and di-acidic signals that mediate, respectively, intracellular trafficking by AP-1 and trafficking to plasma membrane by exomer complex; requires AP-3 complex for its intracellular retention

MSD2, PKX2, polo kinase CDC5, L000000245, YMR001C
Polo-like kinase; controls targeting and activation of Rho1p at cell division site via Rholp guanine nucleotide exchange factors; regulates Spc72p; also functions in adaptation to DNA damage during meiosis; has similarity to Xenopus Plx1 and S. pombe Plo1p; possible Cdc28p substrate

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Phosphorylation of Chs2p regulates interaction with COPII.

Jakobsen MK, Cheng Z, Lam SK, Roth-Johnson E, Barfield RM, Schekman R

Trafficking of the chitin synthase Chs2p from the endoplasmic reticulum (ER) to the bud-neck in late mitosis is tightly regulated by the cell cycle via phosphorylation of serine residues in the N-terminus of the protein. Here, we describe the effects of Chs2p phosphorylation on the interaction with coat protein complex II (COPII). Identification of a cdc5(ts) mutant, which fails to ... [more]
