Evidence:Substrate In Vitro Evidence: Maintaining cytoplasmic acid-base balance: Na+ 115 CHO cells H+ 115 CHO cells Li+ 6 ? NH4+ 6 ? Tissue Distribution Evidence: 1 maintaining cytoplasmic acid-base balance 2 provides a major conduit for Na+ influx, coupled to Cl- and H2O uptake, which is required to restore cell volume to steady-state levels following cell shrinkage induced by acute elevations in external osmolality

GTEx Expression by Gene and Transcript

The heat map summarizes relative expression by tissue type at two levels of tissue detail, e.g., 'Brain' and 'Brain - Amygdala'. Choose among four calculated expression values, including mean and median RPKM values, and quantile normalized (QN) distributions of these values. (Note that differences between some distributions are subtle.) The coloring is relative to the mean of all displayed values. All values are log base 2. (See also PMT GTEx Expression Plotting.) Click on a transcript or tissue to resort the data.
