Ser(982) in the C-terminus of kNBC1 is a target for PKA phosphorylation. Phosphorylation of Ser(982) in the sodium bicarbonate cotransporter kNBC1 shifts the HCO(3)(-) : Na(+) stoichiometry from 3 : 1 to 2 : 1 in murine proximal tubule cells Replacing Ser(982) at the C-terminus consensus PKA phosphorylation site with alanine resulted in a failure of PKA to phosphorylate the transporter and induce a stoichiometry shift. |

WNK kinases acted as scaffolds to recruit SPAK, which phosphorylated CFTR and NBCe1-B, reducing their cell surface expression. IRBIT opposed the effects of WNKs and SPAK by recruiting PP1 to the complex to dephosphorylate CFTR and NBCe1-B, restoring their cell surface expression, |

SPAK phosphorylates the transporters to reduce their surface expression and thus their activity and consequently inhibits ductal secretion to stabilize the resting state. PP1 reverses the effect of SPAK. Molecular analysis revealed that the WNK kinases acted as scaffolds to recruit SPAK, which phosphorylated CFTR and NBCe1-B, reducing their cell surface expression. |

IRBIT opposed the effects of WNKs and SPAK by recruiting PP1 to the complex to dephosphorylate CFTR and NBCe1-B, restoring their cell surface expression, in addition to stimulating their activities. |
