Orthologues of Saccharomyces cerevisiae CCZ1, MON1 and YPT7 genes in the methylotrophic yeast, Pichia pastoris, have been identified. These genes encode proteins, which act as a complex, being involved in degradation of oleate-induced peroxisomes, Cvt (cytoplasm to vacuole targeting) pathway and non-specific macroautophagy in S. cerevisiae. CCZ1, MON1 and YPT7 gene orthologues are essential for multiple delivery pathways in P. pastoris. Strains with deletion of either of these genes displayed complete deficiency in pexophagy, non-specific macroautophagy and the biosynthetic Cvt pathway. The data suggest that CCZ1, MON1 and YPT7 genes are involved in degradation of both small oleate-induced and large methanol-induced peroxisomes. The data suggest conservative functions of CCZ1, MON1 and YPT7 genes among yeast species.
