Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in several processes, including cell dedifferentiation; nervous system development; and regulation of transcription, DNA-templated. Predicted to act upstream of or within nervous system development and positive regulation of neuron differentiation. Predicted to be located in cytosol and nucleoplasm. Human ortholog(s) of this gene implicated in hypogonadotropic hypogonadism 22 with or without anosmia. Orthologous to human FEZF1 (FEZ family zinc finger 1).
