Pituitary homeobox 3 is a protein that in humans is encoded by the PITX3 gene.^[1]^[2]

This gene encodes a member of the RIEG/PITX homeobox family, which is in the bicoid class of homeodomain proteins. Members of this family act as transcription factors. Mutations of this gene have been associated with anterior segment mesenchymal dysgenesis (ASMD) and congenital cataracts. This protein is involved in lens formation during eye development.^[2]
