Kinome-wide CRISPR/Cas9-knockout screening reveals critical protein kinases in vasopressin V2-receptor signaling

A kinome-wide CRISPR knockout screen in a mouse collecting duct Aqp2-GFP reporter line found 26 kinases shaping vasopressin-driven Aqp2 transcription, including Dyrk1a, Stk11 and TGF-β receptors.

CREB-family transcription factors and vasopressin-mediated regulation of Aqp2 gene transcription

This study shows that ATF1, CREB1, and CREM redundantly regulate Aqp2 gene transcription in response to vasopressin in mpkCCD cells.

Vasopressin-Dependent β-Catenin Phosphorylation at Ser552 and Branching Structure of Mouse Collecting Duct System

This study shows that mutating Ser552 in β-catenin in mice alters collecting duct branching without affecting differentiation, suggesting vasopressin-mediated phosphorylation at Ser552 influences CD development.

Circadian Gene Expression in Mouse Renal Proximal Tubule

The paper identifies circadian gene expression patterns in mouse renal proximal tubules and provides a web resource for these data.

Phosphoproteomic Identification of Vasopressin-Regulated Protein Kinases in Collecting Duct Cells

The paper identifies vasopressin-regulated protein kinases in collecting duct cells using phosphoproteomic analysis and finds six downstream kinases account for most phosphorylation sites.

Protein kinase A catalytic-α and catalytic-β proteins have non-redundant functions

The paper identifies non-redundant functions of PKA-C and PKA-Cβ in renal collecting duct cells through phosphoproteomic analysis and shows distinct effects on AQP2 abundance.
