Point mutations of 3BP2 identified in human‐inherited disease cherubism result in the loss of function

Abstract excerpt

Adaptor protein 3BP2 positively regulates the high affinity IgE receptor (FcepsilonRI)-mediated activation of degranulation in mast cells. Genetic study identified the point mutations of 3BP2 gene in human-inherited disease cherubism. The multiple cysts in cherubism lesion of jaw bones are filled with the activated osteoclasts and stromal cells, including mast cells. By over-expression study using rat basophilic...
