Flocculation in Schizosaccharomyces pombe

Deciphering the Transcriptional-Regulatory Network of Flocculation in Schizosaccharomyces pombe

In the fission yeast Schizosaccharomyces pombe, the transcriptional-regulatory network that governs flocculation remains poorly understood. Here, we systematically screened an array of transcription factor deletion and overexpression strains for flocculation and performed microarray expression profiling and ChIP-chip analysis to identify the flocculin target genes. We identified five transcript...

Cloning of the Schizosaccharomyces pombe

Diadenosine 5',5"'-P1,P4-tetraphosphate (Ap4A) asymmetric hydrolase (EC 3.6.1.17) is a specific catabolic enzyme of Ap4A found in Schizosaccharomyces pombe. We have previously described the partial purification ofAp4A hydrolase from S. pombe [Robinson, de la Pefia and Barnes (1993) Biochim. Biophys. Acta 1161, 139-148]. We determined the sequence of the N-terminal 20 amino acids of Ap4A hydrola...

Copper transport and regulation in Schizosaccharomyces pombe.

The fission yeast Schizosaccharomyces pombe has been successfully used as a model to gain fundamental knowledge in understanding how eukaryotic cells acquire copper during vegetative growth. These studies have revealed the existence of a heteromeric Ctr4-Ctr5 plasma membrane complex that mediates uptake of copper within the cells. Furthermore, additional studies have led to the identification o...

Asymmetric inheritance of cytoophidia in Schizosaccharomyces pombe

A general view is that Schizosaccharomyces pombe undergoes symmetric cell division with two daughter cells inheriting equal shares of the content from the mother cell. Here we show that CTP synthase, a metabolic enzyme responsible for the de novo synthesis of the nucleotide CTP, can form filamentous cytoophidia in the cytoplasm and nucleus of S. pombe cells. Surprisingly, we observe that both c...
