چکیده

In order to identify additional components important for cell division in the fission yeast Schizosaccharomyces pombe we have screened a bank of conditional cold-sensitive mutants for cytokinesis defects. One of these mutants showed a delay in cell cleavage, and strong genetic interactions with other genes implicated in medial ring formation. Cloning of the corresponding gene indicates that it encodes a protein with significant homology to the regulatory light chain of non-muscle myosins. We have named the gene rlc1 (regulatory light chain 1). The gene is not essential for division, but null mutants display a cell cleavage defect and form an aberrant F-actin ring. Two myosin-II heavy chains have been identified in fission yeast: Co-immunoprecipitation experiments indicate that rlc1p associates more strongly with myo3p than myo2p.

Type II Myosin Heavy Chain Encoded by the myo2 Gene Composes the Contractile Ring during Cytokinesis in Schizosaccharomyces pombe

We cloned the myo2 gene of Schizosaccharomyces pombe, which encodes a type II myosin heavy chain, by virtue of its ability to promote diploidization in fission yeast cells. The myo2 gene encodes 1,526 amino acids in a single open reading frame. Myo2p shows homology to the head domains and the coiledcoil tail of the conventional type II myosin heavy chain and carries putative binding sites for A...

Interactions of Cdc4p, a myosin light chain, with IQ-domain containing proteins in Schizosaccharomyces pombe.

The fission yeast Schizosaccharomyces pombe undergoes cell division through a medially placed actomyosin-based contractile ring. One of the key components of this ring is the F-actin based motor protein myosin II. The myosin II heavy chain Myo2p has two light-chain-binding domains, IQl and IQ2, which bind the essential light chain, Cdc4p, and the regulatory light chain, Rlc1p. Previously, we ha...

Regulation of fission yeast myosin-II function and contractile ring dynamics by regulatory light-chain and heavy-chain phosphorylation.

We investigated the role of regulatory light-chain (Rlc1p) and heavy-chain phosphorylation in controlling fission yeast myosin-II (Myo2p) motor activity and function during cytokinesis. Phosphorylation of Rlc1p leads to a fourfold increase in Myo2p's in vitro motility rate, which ensures effective contractile ring constriction and function. Surprisingly, unlike with smooth muscle and nonmuscle ...

Fission yeast myosin Myo2 is down-regulated in actin affinity by light chain phosphorylation.

Studies in fission yeast Schizosaccharomyces pombe have provided the basis for the most advanced models of the dynamics of the cytokinetic contractile ring. Myo2, a class-II myosin, is the major source of tension in the contractile ring, but how Myo2 is anchored and regulated to produce force is poorly understood. To enable more detailed biochemical/biophysical studies, Myo2 was expressed in th...

The UCS Domain Protein She4p Binds to Myosin Motor Domains and Is Essential for Class I and Class V Myosin Function

BACKGROUND Myosins are motor proteins involved in processes like cell motility, vesicle transport, or cytokinesis. In a variety of organisms, a novel group of proteins forming the UCS (UNC-45/CRO1/SHE4) domain-containing family are essential for proper myosin function. The Saccharomyces cerevisae UCS domain protein She4p is involved in two myosin-requiring events, endocytosis and mRNA localizat...
