Genes affected

NFIB (HGNC:7785): (nuclear factor I B) Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and transcription regulator inhibitor activity. Involved in brain development; negative regulation of DNA binding activity; and regulation of transcription by RNA polymerase II. Located in fibrillar center and nucleoplasm.
