Prox1 cDNA Clones

Prox1, the homolog of Drosophila Prospero, is a homeobox-containing transcription factor that binds and functions as a co-receptor of liver receptor homolog 1 (LRH1/NR5A2). It is a specific marker for lymphatic endothelial cells, as well as hepatoblasts and hepatocytes. Human Prox1 shares 97% amino acid sequence identity with mouse and rat Prox1.
