abstract：:In previous studies, we detected a major, unidentified Egr response element (ERE) binding complex in brain extracts. We now report that this complex contains a truncated isoform of Egr3 generated by use of an alternate translation start site at methionine 106. Furthermore, the ERE binding complex previously thought to...
