palB — Magnaporthe oryzae 70-15

Summary

MGG_15810 (symbol palB) on chromosome 2 of Magnaporthe oryzae 70-15 encodes a calpain catalytic domain-containing protein with calcium-dependent cysteine-type endopeptidase activity. The gene is associated with proteolysis, signal transduction, and the regulation of secondary metabolite biosynthesis, including activation of penicillin anabolism. It is linked to appressorium formation, sporulation, mating, and responses to chemical stimuli, pH, and glucose. The encoded protein localises to the ESCRT III complex. Related genes in other species encode calpain-like proteins, though these associations are not yet established for M. oryzae.
