Activator of the chitin synthase CHS3 which polymerizes chitin, a structural polymer of the fungal cell wall (PubMed:16278457, PubMed:17400891). Chitin produced by CHS3 is deacetylated to chitosan, which helps to maintain cell wall integrity, anchor melanin, and offers an advantage during infection, as chitosan is less readily detected by host immunosurveillance (PubMed:16278457, PubMed:17400891, PubMed:32071275). Farnesylation is not required for cellular membrane localization. Increases cellular chitin level and decreases cellular chitosan level (PubMed:16278457, PubMed:17400891). Swollen cell with abnormal cytokinesis (PubMed:16278457, PubMed:17400891). Melanization of surrounding media (PubMed:16278457, PubMed:17400891). Irregular capsular width (PubMed:17400891). Sensitive to: high temperature, Congo Red (cell wall stressor), caspofungin (cell wall stressor), sodium dodecyl sulfate (cell wall stressor), Calcofluor White (cell wall stressor), caffeine, NaCl (osmotic stressor) (PubMed:16278457, PubMed:17400891, PubMed:31266771). Belongs to the SKT5 family.
