The Pax2 gene ('paired box 2') encodes the protein, PAX 2.
PAX2 is a transcription factor that acts to regulate the expression of genesinvolved in mediating cell proliferation and growth, resistance to apoptosis, the main function is PAX2 gene (protein-coding), paired box 2. The PAX2 gene belongs to a family of genes that plays a critical role in the formation of tissues and organs during embryonic development. During embryonic development, the PAX2 gene provides instructions for producing a protein that is involved in the formation of the eye, ear, brain and spinal cord (central nervous system), kidney, and genital tract. After birth, the PAX2 protein is thought to protect against cell death during periods of cellular stress.
