Summary: Enables DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and transcription corepressor binding activity. Involved in several processes, including generation of neurons; heart development; and regulation of transcription by RNA polymerase II. Predicted to be located in chromatin. Predicted to be active in nucleus. Is expressed in several structures, including anlage in statu nascendi; epidermis; follicle cell; imaginal disc; and segmentally-repeated neuroblast. Used to study cardiomyopathy and congenital heart disease. Human ortholog(s) of this gene implicated in atrial heart septal defect; atrial heart septal defect 4; congenital heart disease; tetralogy of Fallot; and ventricular septal defect. Orthologous to human TBX20 (T-box transcription factor 20). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Data suggest that midline protein (mid) and H15 protein (H15) specify ventral fate through inhibition of decapentaplegic protein (Dpp) signaling and through coordinating the repression of genes in the ventral leg.
Title: The selector genes midline and H15 control ventral leg pattern by both inhibiting Dpp signaling and specifying ventral fate.
Taken together, the authors propose that Mid regulates wing development by repressing wg and hh in Drosophila.
Title: The T-box transcription factor Midline regulates wing development by repressing wingless and hedgehog in Drosophila.
Mid and dFOXO serve as critical effectors of cell fate specification and survival within integrated Notch, InR/dAkt, and JNK signaling pathways during 3(o)L and pupal eye imaginal disc development.
