Hunchback is a maternal effect gene and gap gene found in the egg and zygotic genome of Drosophila embryogenesis. It is activated by the maternal Bicoid morphogen gradient and determines the anterior-posterior axis within the syncytial blastoderm.[1] Hunchback is a Zinc finger transcription factor that coordinates the expression of other gap genes such as Krüppel, knirps, and giant.[2]

Hunchback protein is expressed in the neuroblasts of many insects, not just Drosophila. Maternal hunchback gene expression is not only found in insects, but also annelids and nematodes.[3]
