The FEZF2 gene encodes the Fez Family Zinc Finger Protein 2. While the exact function of the FEZF2 gene in humans is yet to be understood, ortholog studies in animals such as mice and zebrafish have helped elucidate its role. Based on these ortholog studies, FEZF2 is believed to function as a transcriptional activator and repressor and to bind to metal ions and chromatin. By carrying out its function, FEZF2 is speculated to be involved in several biological processes such as the regulation of neuron differentiation, cell proliferation, axon guidance and axonal fasciculation, dendrite development, cerebral cortex GABAergic interneuron migration, and forebrain anterior/posterior pattern specification.
