Focus of this project is the CaaX
processing microcompartment transiently formed at the ER, which is required for the modification of yeast Chs4, a regulatory subunit of the chitin synthase (CHS) III complex.
The key players in this
process are the SNAREs (soluble N - ethylmaleimide - sensitive - factor attachment receptors), which drive fusion, and S / M (Sec1 / Munc18) family proteins that act as universal organizers of fusiogenic
microcompartments and activators of SNARE - mediated membrane fusion.
