Major secreted protein that belongs to the subtilisin family serine proteases.6 Publications

Miscellaneous

The pro-region inhibits protease activity (PubMed:2649495) and plays an additional essential role in the proper folding of the protein into a conformation compatible with secretion (PubMed:1995632, PubMed:1634541).3 Publications
Its complex processing and high level of secretion make XPR2 the perfect model to study the secretion pathway.2 Publications

Caution

Strain CLIB 122 / E 150 has a defective XPR2 sequence (xpr2-322) which lacks the N-terminus (positions 1 to 34).Curated

The protease activity is completely inhibited by the serine inhibitor PMSF but is not affected by thiol group inhibitors and in the presence of dithiothreitol (PubMed:6750031). In the presence of high concentrations of o-phenanthroline the protease activity is only partially inhibited (PubMed:6750031). The pro-region plays an inhibitory role and may provide a mechanism for preventing premature activation in the secretory pathway (PubMed:2649495).2 Publications

Expression is subject to at least 3 different regulatory controls, carbon, sulfur and nitrogen repression (PubMed:870075). Intracellular cysteine and ammonia appear to be the metabolic signals for sulfur and nitrogen repression (PubMed:870075). Moreover, pH regulates expression independently from other metabolic signals, with highest levels of AEP mRNA at pH 6.5 (PubMed:8842151, PubMed:9308186). The transcriptional activator RIM101 and the Rim pathway are required for the alkaline induction of gene expression (PubMed:9199331, PubMed:11861549). Two major upstream activation sequences (UASs) are essential for promoter activity under conditions of repression or full induction. The distal UAS (UAS1) is located at position -790 to -778, whereas the proximal UAS (UAS2) localizes at positions -148 to -124 (PubMed:8264600, PubMed:10206713).7 Publications
