The mast cell-specific expression of a protease gene, RMCP II, is regulated by an enhancer element that binds specifically to mast cell trans-acting factors.

Journal Article (Journal Article)

The rat mast cell protease gene, RMCP II, is specifically expressed in the mucosal subclass of rat mast cells. We show here that the 5'-flanking region of this gene contains a mast cell-specific enhancer that directs preferential expression of a linked reporter gene (human growth hormone) transfected into rat basophilic leukemia cells. A DNA fragment containing the enhancer sequence is capable of binding specifically to mast cell nuclear trans-acting factors. The sequence of this enhancer element contains a region of homology to a consensus core sequence present in the enhancer region of the pancreatic protease genes.
