A<unk>  is a DNA sequence found within genes that are involved in the regulation of development (morphogenesis) of animals, fungi and plants. Genes that have a<unk>  are called<unk>  genes and form the<unk>  gene family.<unk>  genes encode homeodomain protein products that are transcription factors sharing a characteristic protein fold structure that binds DNA to regulate expression of target genes.
Homeodomain proteins regulate gene expression and cell differentiation during early embryonic development, thus mutations in<unk>  genes can cause developmental disorders.
