Caracterización de las ?-1,3-glucanosil-transferasas de la familia GH72 implicadas en la remodelación de la pared celular de Schizosaccharomyces pombe

Diversas proteinas pertenecientes a la familia 72 de las glicosil-hidrolasas (GH72) con actividad s-1,3-glucanosil-transferasa han sido caracterizadas en otros organismos (Gas1p, Gas2p y Gas4p de Saccharomyces cerevisiae, o Gel1p de Aspergillus fumigatus).

Regulation of the Subcellular Localization of Cyclic AMP-Dependent Protein Kinase in Response to Physiological Stresses and Sexual Differentiation in the Fission Yeast Schizosaccharomyces pombe

It is demonstrated that PKA localization is regulated by cAMP and regulatory subunit-dependent and -independent mechanisms in S. pombe in response to physiological stresses and during sexual differentiation.

Interaction between Pheromone and Its Receptor of the Fission Yeast Schizosaccharomyces pombe Examined by a Force Spectroscopy Study

Interaction between P-factor and Mam2 on the cell surface of the fission yeast Schizosaccharomyces pombe was examined by an atomic force microscope and the specific interaction force was calculated to be around 120 pN at a probe speed of 1.74 μm/s.

The tetraspan protein Dni1p is required for correct membrane organization and cell wall remodelling during mating in Schizosaccharomyces pombe

Results show that Dni1p plays a relevant role in co‐ordinating membrane organization and cell wall remodelling during mating, a function that has not been described for other proteins in the fission yeast.

MFα1, the Gene Encoding the α Mating Pheromone of Candida albicans

The isolation and characterization of the gene MFα1, which codes for the precursor of the α mating pheromone in C. albicans, is reported, which is able to complement the mating defect of an MTLα kex2 mutant strain when added exogenously.

Influence of activated A and B mating-type pathways on developmental processes in the basidiomycete Coprinus cinereus

The B genes control fruiting body maturation at the stage of karyogamy, and A-induced fruiting occurs more efficiently and earlier when the B mating type pathway is also active (Bon), however, activation of the B pathway alone is not sufficient to induce fruiting.

Role of the Tsc1-Tsc2 complex in signaling and transport across the cell membrane in the fission yeast Schizosaccharomyces pombe.

The results indicate that the fission yeast Tsc1-Tsc2 complex plays a role in the regulation of protein trafficking and suggest a similar function for the human proteins.

A temperature‐sensitive Krp1 allows in vivo characterization of kexin activation

It is shown that prosegments lacking an internal dibasic motif can act as autoinhibitors and prevent activation of the catalytic fragment in Krp1, a kexin from the fission yeast Schizosaccharomyces pombe.

The Role of the RACK1 Ortholog Cpc2p in Modulating Pheromone-Induced Cell Cycle Arrest in Fission Yeast

Investigations into the role, which Cpc2p performs in controlling the G protein-mediated mating response pathway are described, which indicates that CPC2p regulates the pheromone-induced cell cycle arrest in fission yeast by delaying cells entry into S phase.

Sxa2 is a serine carboxypeptidase that degrades extracellular P‐factor in the fission yeast Schizosaccharomyces pombe

The first molecular characterization of the Sxa2 protein is reported and direct evidence is provided that it is the carboxypeptidase that degrades P‐factor that contributes to desensitization in M‐cells.



G-protein-coupled receptor regulation: role of G-protein-coupled receptor kinases and arrestins

GRK-mediated phosphorylation and arrestin binding are not only involved in the functional uncoupling of GPCRs but they are also intimately involved in promoting GPCR sequestration and as such likely play an important role in mediating the subsequent resensitization of G PCRs.

12 Mating and Sporulation in Schizosaccharomyces pombe

Haploid cells of the fission yeast Schizosaccharomyces pombe display one of the two mating types, and h + and h − cells elongate conjugation tubes toward each other, which results in the enhanced production of mating pheromones and their receptors.

Localization of F-actin through the cell division cycle of Schizosaccharomyces pombe.

Etude de la localisation de the F-actine durant les etapes du cycle cellulaire de S. pombe montrant qu'elle coincide avec the deposition of the paroi cellulaires and qu'elles disparait faisant place a un anneau equatorial d'actine a la mitose.

A novel aspartyl protease allowing KEX2‐independent MFα propheromone processing in yeast

The amino acid sequence deduced from the gene shows extensive homology to a number of aspartyl proteases including the PEP4 and BARI gene products from S. cerevisiae and contains a C‐terminal serine/threonine‐rich sequence and potential transmembrane domain similar to those found in the KEX2 gene product.

Structure of Tremerogen A–10, a Peptidal Hormone Inducing Conjugation Tube Formation in Tremella mesenterica

The structure of tremerogen A-10 is proposed and it is strongly suggested that Cterminus may be blocked by methyl ester function and an isoprenoidal moiety is con nected to the sulfhydryl function of cysteine residue.


The results suggest that the four-lined-cell is to be regarded as one unit with respect to zygote formation.

Sterility (ste) genes of Schizosaccharomyces pombe

Two hitherto unknown ste genes, ste7 and ste8, were found and succeeded in achieving sporulation with these mutants of Schizosaccharomyces pombe.
