AQP2 — PRKAR1B
Text-mined interactions from Literome
Hasler et al., J Am Soc Nephrol 2005
:
These results indicate that in collecting duct principal cells : ( 1 ) a short-term increase of extracellular osmolarity decreases AQP2 expression through inhibition of
AQP2 gene transcription ; ( 2 ) a long-term increase of extracellular tonicity, but not osmolarity, enhances AQP2 expression via stimulation of AQP2 gene transcription ; and ( 3 ) long-term hypertonicity and
PKA increases AQP2 expression through synergistic but independent mechanisms
Li et al., J Am Soc Nephrol 2006
(Diabetes Insipidus, Nephrogenic...) :
Surprising, the effect of lithium was cAMP independent ; it did not alter AVP stimulated cAMP production or
PKA dependent phosphorylation of
AQP2 or cAMP responsive element binding protein
Umenishi et al., Biochim Biophys Acta 2006
:
PKA activity was
stimulated by AVP but
PKA inhibitors did not block the upregulation of
AQP2 expression
Bouley et al., J Am Soc Nephrol 2011
:
Pharmacologic inhibition of
protein kinase A (PKA) and deficiency of a critical PKA phosphorylation site on AQP2 both
prevented calcitonin induced membrane accumulation of
AQP2
