摘要

Brn-4 is a member of the POU transcription factor family and is expressed in the central nervous system. In this study, we addressed whether Brn-4 regulates expres- sion of the D_1A dopamine receptor gene. We found a functional Brn-4 responsive element in the intron of this gene by means of cotransfection chloramphenical acetyltransferase assays. This region contains two consensus sequences for binding of POU factors. Gel mobility-shift assays using glutathione S-transferase-Brn-4 fusion protein indicated that Brn-4 binds to these sequences.
