Stm1 is a vacuolar PQ-loop protein involved in the transport of basic amino acids in Schizosaccharomyces pombe.

The stm1 (SPAC17C9.10) gene of Schizosaccharomyces pombe is closely related to genes encoding vacuolar PQ-loop proteins, Ypq1, Ypq2, and Ypq3, of Saccharomyces cerevisiae. When stm1 fused with GFP was expressed in fission or budding yeast, Stm1-GFP localized at the vacuolar membrane.

Catechol O-methyltransferase homologs in Schizosaccharomyces pombe are response factors to alkaline and salt stress.

How cells of the fission yeast Schizosaccharomyces pombe respond to alkaline stress is not well understood. Here, to elucidate the molecular mechanism underlying the alkaline stress response in S. pombe, we performed DNA microarray analysis.

Analysis of ambient pH stress response mediated by iron and copper intake in Schizosaccharomyces pombe.

The molecular mechanism of tolerance to alkaline pH is well studied in model fungi Aspergillus nidulans and Saccharomyces cerevisiae. However, how fission yeast Schizosaccharomyces pombe survives under alkaline stress remains largely unknown, as the genes involved in the alkaline stress response pathways of A. nidulans and S.
