csn — Neurospora crassa

Summary

NCU02909, symbol csn, on Neurospora crassa chromosome 1 encodes a fungal chitosanase (EC 3.2.1.132) with chitosanase activity. The gene is associated with polysaccharide breakdown, regulation of breakdown, and protein modification. It has been associated with circadian rhythm, chromatin silencing, ubiquitin-dependent proteolysis, secondary metabolism, protein breakdown, hyphal growth, methylation, and DNA repair. The encoded product is localised extracellularly. Studies of related genes in other species link the family to pathogenesis, though this is not established for N. crassa.
