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

MYO1

myosin 1, L000001222, YHR023W
Type II myosin heavy chain; required for wild-type cytokinesis and cell separation; localizes to the actomyosin ring; binds to myosin light chains Mlc1p and Mlc2p through its IQ1 and IQ2 motifs respectively
Saccharomyces cerevisiae (S288c)

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.

In budding yeast, contraction of the actomyosin ring and formation of the primary septum at cytokinesis depend on each other.

Schmidt M, Bowers B, Varma A, Roh DH, Cabib E

Saccharomyces cerevisiae chs2 mutants are unable to synthesize primary septum chitin, and myo1 mutants cannot construct a functional contractile ring. The morphology of the two mutants, as observed by electron microscopy, is very similar. In both cases, neither an invagination of the plasma membrane, which normally results from contraction of the actomyosin ring, nor generation of a chitin disc, the ... [more]
