Ypt1ps
Ypt1ps is a protein found in the yeast species Saccharomyces cerevisiae. It belongs to the Ypt family of proteins, which are small GTPases that play critical roles in intracellular membrane trafficking. Ypt1ps is specifically involved in the early secretory pathway, mediating vesicle transport between the endoplasmic reticulum and the Golgi apparatus.
The function of Ypt1ps is regulated by its binding to guanine nucleotides. In its GTP-bound state, Ypt1ps
Mutations or deficiencies in Ypt1ps can lead to severe defects in secretion and cell viability. Studies of
