PAX4

Gene ontology

Molecular function:

• transcription factor activity
• sequence-specific DNA binding

Cellular component:

Biological process:

• regulation of transcription, DNA-dependent
• multicellular organismal development
• organ morphogenesis
• cell differentiation

This gene is a member of the paired box (PAX) family of transcription factors. Members of this gene family typically contain a paired box domain, an octapeptide, and a paired-type homeodomain. These genes play critical roles during fetal development and cancer growth. The paired box gene 4 is involved in pancreatic islet development and mouse studies have demonstrated a role for this gene in differentiation of insulin-producing beta cells.¹
