WebJun 17, 2024 · Notably, in the physiological range of cytosolic pH (i.e., 6.8 to 8), the KdNO3 of ClopHensor was between 5 and 25 mM ( SI Appendix, Fig. S1 ), which is in the range of the previously reported [NO 3−] cyt values of about 5 mM ( 35 ), therefore making it suitable to monitor the dynamics of this anion. WebNormally PHO8 is synthesized at the ER, delivered to the vacuole via the secretory pathway, and then cleaved to generate an active form of the protein. To monitor autophagy, the Pho8Δ60 mutant protein is expressed. Pho8Δ60 localizes to the cytosol in an inactive form unless autophagy is induced.

WebIntracellular pH is generally between ~6.8 and 7.4 in the cytosol and ~4.5 and 6.0 in the cell’s acidic organelles.
