Prospero homeobox protein 1 is a protein that in humans is encoded by the PROX1 gene. Template:PBB Summary

Interactions

PROX1 has been shown to interact with EP300.

Production

PROX1 is produced primarily in the dentate gyrus in the mouse, and in the dentate gyrus and white matter in humans. Gene expression data for mouse, human and macaque from the Allen Brain Atlases can be found here.

Clinical significance

PROX1 is used as a marker for lymphatic endothelium in biopsy samples.
