cNkx2-8 represents a novel member of the NK2-family transcription factors. The gene contains three highly conserved regions, the TN-, NK2-, and homeodomains which are diagnostic for this group of proteins. cNkx2-8 is expressed during chick embryogenesis in ventral foregut endoderm, myocardial mesoderm, epithelium of the branchial arches and the dorsal mesocardium. While cNkx2-8 expression parti...
