Abstract | The mitogen-activated protein kinase (MAPK) Hoglp plays an essential role in the yeast hyperosmotic response. A homolog of the HOG1 gene was isolated from the halophilic black yeast Hortaea werneckii encoding a putative 359 amino acid protein, HwHoglp, with high homology to Saccharomyces cerevisiae Hoglp and to other eukaryotic Hoglp homologs. HwHoglp contains a TGY motif within a protein kinase catalytic domain and a C-terminal common docking (CD) motif. Its activation by increased salinity is regulated at the posttranscriptional level. HwHoglp is located on the plasma membrane under nonstress conditions. Upon increased external salinity it is translocated from the membrane, presumably to the nucleus. | |
