Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in developmental process and negative regulation of transcription by RNA polymerase II. Predicted to act upstream of or within cell development; floor plate development; and regulation of neurogenesis. Predicted to be located in nucleus. Orthologous to human FERD3L (Fer3 like bHLH transcription factor). [provided by Alliance of Genome Resources, Apr 2022]
