Quantitative proteinomics on WWP2 overexpressed human tubular epithelial cells HK-2

WWP2 is a E3 ligase which regulates multiple cellular events, such as stress response, differentiation. WWP2 played physiological role in the distal tubules of the kidneys. Whether WWP2 regulated pathophysiological rol in the proximal tubules is unclear. In the present study, we stably overexpressed WWP2 using lenti-viral infection in the human tubular epithelial cells, HK-2, and performed proteinomics analysis to explore WWP2's potential substrates.
