3.4.16.6 malfunction absence of Kex1p diminishes HOCl-induced production of reactive oxygen species, apoptosis and protein modification 731598 3.4.16.6 malfunction kexA deletion strain shows slightly lower growth speed. Deletion strain exhibits scarcely branched hyphae, whereas an kexA-overexpressing strain exhibits a hyperbranching phenotype 731176 3.4.16.6 malfunction LNCap cells treated with CPD siRNA show a decreased NO production and cell viability, but increased apoptosis 732850 3.4.16.6 malfunction targeted reduction of CPD in Huh7 cells results in decreased growth and enhanced apoptosis of Huh 7 cells in vitro 731593 3.4.16.6 physiological function CpD is the only endogenous carboxypeptidase that cleaves antibody heavy chain C-terminal lysine in CHO cells. Knockdown of CpD by RNAi increases C-terminal lysine levels of antibodies, whereas there is no obvious change in C-terminal lysine levels when carboxypeptidase CpM, CpN, CpB, or CpE is knocked downIn a CpD knockout mutant, C-terminal lysine cleavage is completely abolished 753046 3.4.16.6 physiological function CPD-mediated production of nitrix oxide promotes the survival of LNCaP cells 732850 3.4.16.6 physiological function protease Kex1p mediates HOCl-induced lethality 731598
