AAV with ELA1 promoter driven Mito-roGFP1

This AAV expresses Mito-roGFP1 driven by a pancreatic acinar ELA1 promoter.

Rat elastase 1 (Ela1; ELAI1; RATELAI1), also called chymotrypsin-like elastase family, member 1, is the major protease with elastin-degrading activity in the mammalian exocrine pancreas. The ELA1 promoter (0.3Kb) is comprised of the core promoter and enhancer, and directs transgene expression in pancreatic acinar cells, stomach, duodenum, and colon.

The mitochondrial targeting sequence of human pyruvate dehydrogenase alpha 1 (PDHA1) is fused in-frame with the redox-sensitive green fluorescent protein (roGFP1). The Mito-roGFP1 is a biosensor for investigating the mitochondrial reduction-oxidation potential.
