Molecular Function of the WW Domain in Signaling and Diseases of the Kidney

Our goal is to elucidate signaling networks that use a modular protein domain, known as the WW domain, which mediates well-defined protein-protein interactions with proline motif-containing ligands. Missense point mutations mapped within the domain or its ligand have been implicated in several human diseases, including Liddle syndrome of hypertension and Golabi-Ito-Hall syndrome of intellectual disability.  Our aim is to characterize signaling changes caused by genetic lesions that affect the WW domain complexes and result in human disease, with a special focus on diseases of the kidney. The ultimate goal of our research is to predict and design molecular tools for interventions in WW domain-mediated pathways to correct pathological states.

Two projects have been pursued in close collaboration between the Nephrology Division and the Sudol Laboratory: (I) In collaboration with Kirk Campbell, we are studying the role of the WW domain-containing protein YAP (Yes kinase-associated protein) in the biology of podocytes. YAP is a transforming gene of chromosome 11q22 amplicon, and its expression is elevated at a high frequency in human cancers, including cancers of liver, breast, ovary and prostate. YAP is also the main effector of a tumor suppressor pathway, known as HIPPO, which regulates a balance between cell proliferation and apoptosis. In podocytes, YAP exerts anti-apoptotic signaling. Understanding the mechanism of pro-survival function of YAP in podocytes shouldidentify new drug targets for management of kidney diseases, resulting from the loss of podocytes.  (II) We have investigated the role of WW domain-containing proteins in the regulation of polycystin 1 (PKD1). In particular, we have identified Protein Kinase X as a modulator of PKD1-WW domain complex that assembles on the cytoplasmic tail of PKD1 and regulates embryonic development of the kidney.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr.Sudol is not currently required to report Industry relationships.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
