The protein encoded by this gene is a nuclear protein that belongs to the family of Kruppel-like C2H2 zinc finger proteins. It functions as a DNA-binding transcription factor by using distinct zinc fingers in different signaling pathways. Thus, it is thought that this gene may have multiple roles in signal transduction during development.[7] Mice lacking the homologous gene Zfp423 have defects in midline brain development, especially in the cerebellum,[8][9][10] as well as defects in olfactory development,[11] and adipogenesis.[12][13] Patients with mutations in ZNF423 have been reported in Joubert Syndrome and nephronophthisis.[14]
