    Summary
    Enables DNA-binding transcription activator activity, RNA polymerase II-specific and sequence-specific DNA binding activity. Involved in several processes, including adult somatic muscle development; dorsal appendage formation; and positive regulation of transcription elongation by RNA polymerase II. Located in cytosol and nucleus. Is expressed in several structures, including egg chamber; embryonic dorsal vessel; gonad; mesoderm; and muscle cell. Orthologous to human ZNF281 (zinc finger protein 281). [provided by Alliance of Genome Resources, Dec 2024]

    What's a GeneRIF?
    1. CF2 expression variations yield altered Mef2 expression levels but with correct spatio-temporal Mef2 expression patterns, it can be concluded that only the mechanism controlling expression levels is de-regulated. Here, it is proposed that CF2 regulates Mef2 expression through a Feedforward Loop circuit.
      Title: CF2 transcription factor is involved in the regulation of Mef2 RNA levels, nuclei number and muscle fiber size.
    2. These results indicate a role for CF2 as a direct negative regulator of the thin filament protein gene Actin 88F.
