Homeobox protein DLX-3 is a protein that in humans is encoded by the DLX3 gene.
Dlx3 is a crucial regulator of hair follicle differentiation and cycling. Specifically, colocalization of phosphorylated Smad1 / 5 / 8 complex and Dlx3 regulate role for BMP signaling to Dlx3 during hair morphogenesis in animal models.
Many vertebrate homeo box-containing genes have been identified on the basis of their sequence similarity with Drosophila developmental genes. Members of the Dlx gene family contain a homeobox that is related to that of Distal-less (Dll), a gene expressed in the head and limbs of the developing fruit fly. The Distal-less (Dlx) family of genes comprises at least 6 different members, DLX1-DLX6. This gene is located in a tail-to-tail configuration with another member of the gene family on the long arm of chromosome 17.
