Activation of Ca2+/calmodulin-dependent protein kinase II is involved in hyperosmotic induction of the human taurine transporter.

abstract：:The dual function of the regulatory beta-subunit of protein kinase CK2 is highlighted by its ability to abolish calmodulin phosphorylation in contrast to its stimulatory effect on the phosphorylation of peptide substrates. Here we show that a synthetic peptide reproducing the C-terminal region of the beta-subunit (bet...
