CP1 — Magnaporthe oryzae 70-15

Summary

MGG_00775 (CP1, also known as KEX1) in Magnaporthe oryzae 70-15 on chromosome 5 encodes a serine carboxypeptidase (EC 3.4.16.6) belonging to the peptidase S10 and alpha/beta hydrolase families. The gene is associated with proteolysis, hyphal growth, positive regulation of conidium formation, fHC assembly, chromatin silencing, and apoptotic processes, and its product localizes to the trans-Golgi network. Phenotypic associations include altered cell death, autophagy, endocytosis, protein secretion, nuclear fusion during mating, prion inheritance, and increased lifespan. The gene is also linked to abnormal Golgi morphology, decreased cytokinesis, and increased aneuploidy. Studies of related genes in other species connect the family to apoplastic effector function and floral organ identity, though these are not established for this gene.
