Paired box gene 2, also known as PAX2 is a protein which in humans is encoded by the PAX2 gene.[1][2]



PAX2 encodes paired box gene 2, one of many human homologues of the Drosophila melanogaster gene prd. The central feature of this transcription factor gene family is the conserved DNA-binding paired box domain. PAX2 is believed to be a target of transcriptional suppression by the tumor suppressor gene WT1.

Clinical significance

Mutations within PAX2 have been shown to result in optic nerve colobomas and renal hypoplasia. Alternative splicing of this gene results in multiple transcript variants.[3]


PAX2 has been shown to interact with PAXIP1.[4]
