PEP4 Antibody

1. Pep4 mutant cells are highly sensitive to oxidative and apoptotic stress induced by hydrogen peroxide and acetic acid. PMID: 29224051
2. Study discuss the structure and physiological function of PEP4, and its transport routes: the Golgi-to-vacuole pathway and the constitutive Golgi-to-plasma membrane pathway. In addition, it is briefly discussed that calcium homeostasis plays an important role in the secretory pathway of proteins, implying that the regulation of PrA delivery to the plasma membrane requires the involvement of calcium ion. [review] PMID: 29124367
3. The propeptide of yeast cathepsin D inhibits programmed necrosis. PMID: 21593793
4. The finding that both mitochondrial AAC proteins and the vacuolar Pep4p interfere with mitochondrial degradation suggests a complex regulation and interplay between mitochondria and the vacuole in yeast programmed cell death.[Pep4 & AAC] PMID: 20345665
5. concluded that increases in reactive-oxygen species and nuclear pore complex permeability occur relatively early during H2O2-induced cell death; later, Pep4p migrates out of vacuoles and degrades nucleoporins after the cells are effectively dead PMID: 16183335
6. results indicate that Pep4p is important for protein turnover after oxidative damage; however, increased removal of oxidized proteins is not sufficient to enhance lifespan PMID: 17159212
7. the lag phase of cell growth of partial PrA (PEP4) gene deletion mutant (36 h) and PrA-negative mutant (48 h) was significantly extended, compared with the wild type strain (24 h) (P<0.05), but PrA had no effect on glucose metabolism PMID: 19817002
