PAX2, or the so-called paired box gene 2, directs the transgene expression of the mid-hindbrain and developing kidney and has three distinct MHB-specific enhancers in its upstream region.
Paired box gene 2, also known as PAX2 is a protein which in humans is encoded by the PAX2 gene. Transgene expression of the mid-hindbrain and developing kidney is directed by Pax2. There are three distinct MHB-specific enhancers in the upstream region of Pax2.
