Research Interest and Specialties

Most of my lab is dedicated to determining the role of CLCA2 in mammary epithelial differentiation, DNA damage response, and breast cancer progression. As a co-discoverer of the CLCA gene family, I identified numerous members of the CLCA family from bovine, mouse, and humans and showed that certain members of the family are stress-responsive inhibitors of cell proliferation that are downregulated with tumor progression. I corrected previously published structural predictions and showed that CLCA2 is a type I transmembrane protein whose ectodomain is cleaved and shed from the cell surface. My lab is probing the molecular and physiological functions of this protein in cultured cells and a mouse knockout model. To this end, we have identified interacting proteins that illuminate its role in differentiation and response to DNA damage in breast epithelium. These studies led to the key discovery that CLCA proteins regulate intracellular calcium signaling.
