Transcription factor that acts as a transcriptional activator (PubMed:24886874). Binds cooperatively with POU3F2/BRN2 or POU3F1/OCT6 to gene promoters, which enhances transcriptional activation (By similarity). Acts as a transcriptional activator of TEAD2 by binding to its gene promoter and first intron (By similarity). Plays a redundant role with SOX4 and SOX12 in cell survival of developing tissues such as the neural tube, branchial arches and somites, thereby contributing to organogenesis (By similarity). Expressed primarily in the brain and heart, with low expression in the kidney, pancreas and muscle. Expressed primarily in the fetal brain, with low expression in the lung, and kidney at 6-7 weeks dpc (PubMed:8666406, PubMed:24886874). Weak expression in the fetal heart and muscle (PubMed:24886874). The disease is caused by variants affecting the gene represented in this entry.
