Loss of Podocyte aPKCλ/ι Causes Polarity Defects and Nephrotic Syndrome

Abstract excerpt

Atypical protein kinase C (aPKC) is a central component of the evolutionarily conserved Par3-Par6-aPKC complex, one of the fundamental regulators of cell polarity. We recently demonstrated that these proteins interact with Neph-nephrin molecules at the slit diaphragm of the glomerular filtration barrier. Here, we report that podocyte-specific deletion of aPKClambda/iota in mice results in severe proteinuria,...
