Research Interests:
Cullin 4B is a scaffold protein that assembles cullin-RING ubiquitin ligase complexes. Recent studies have revealed that germ-line mutations inCUL4Bcan cause mental retardation, short stature and many other abnormalities in humans. Our studies focus on the separation and identification of specific CUL4B substrates and further understanding the pathogenesis caused by CUL4B-deficiency in humans.
