Activator of the chitin synthase CHS3 which polymerizes chitin, a structural polymer of the fungal cell wall. May interact with CHS3 and seems to be an adapter (along with BNI4) to link CHS3 to septins. Farnesylation is not required for cellular membrane localization. Induced by Calcofluor White (PubMed:9234668). Repressed by alpha-factor (PubMed:9234668). Unchanged during sporulation (PubMed:9234668). Farnesylation is required for chitin synthase CHS3 activity but is not required for SKT5 membrane association. Decreases CHS3 chitin synthase activity (PubMed:9234668). Decreases cellular chitin level (PubMed:9234668). Resistance to Calcofluor White (cell wall stressor) (PubMed:9234668). Normal CHS3 RNA level (PubMed:9234668). Decreases conjugation frequency (PubMed:9234668). Present with 2580 molecules/cell in log phase SD medium. Belongs to the SKT5 family. It is uncertain whether Met-1 or Met-15 is the initiator.
