Sophisticated spectroscopic analyses identified positively charged proteins that inhibit stone formation. The researchers detected three new proteins - histone-lysine N-methyltransferase, inward rectifier K channel and protein Wnt-2, the research highlight said.

"We identified histone-lysine N-methyltransferase, inward rectifier K channel and protein Wnt-2 as novel antilithiatic proteins which play a vital role in the kidney function and have been associated with various kidney diseases," the researchers said.
These proteins were purified and their effects on calcium oxalate stone formation and stone-induced injury to dog kidney epithelial cells were studied. Purified proteins showed significant inhibition of calcium oxalate crystal nucleation and growth and showed protective effects toward the cell injury caused by oxalate.
