Zinc finger and BTB domain-containing protein 7A is a protein that in humans is encoded by the ZBTB7A gene. Enables several functions, including SMAD binding activity; androgen receptor binding activity; and transcription corepressor binding activity. Involved in several processes, including erythrocyte maturation; negative regulation of signal transduction; and regulation of nucleobase-containing compound metabolic process. Located in cytoplasm and nucleus. Colocalizes with DNA-dependent protein kinase complex and NuRD complex.
