Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific; DNA-binding transcription repressor activity, RNA polymerase II-specific; and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including nervous system development; positive regulation of glial cell differentiation; and regulation of gene expression. Located in cytoplasm and nucleus. Is expressed in several structures, including brain; glial cell; glioblast; imaginal disc; and sensory nervous system primordium. [provided by Alliance of Genome Resources, Dec 2024]
