Transcriptional repressor that may play a role in the specification and differentiation of lung epithelium. May also play a role in developing neural, gastrointestinal and cardiovascular tissues. Can act with CTBP1 to synergistically repress transcription but CTPBP1 is not essential. Involved in neural mechanisms mediating the development of speech and language. Forms homodimers and heterodimers with FOXP1 and FOXP4. Dimerization is required for DNA-binding. Interacts with CTBP1. Isoform 1 and isoform 6 are expressed in adult and fetal brain, caudate nucleus and lung. 9 isoforms of the human protein are produced by alternative splicing.

Protein type: C2H2-type zinc finger protein; DNA-binding
