Summary: Enables sequence-specific DNA binding activity. Involved in several processes, including germ cell migration; nervous system development; and salivary gland morphogenesis. Located in nucleus. Is expressed in several structures, including ectoderm anlage; extended germ band embryo; germ layer; procephalic segment; and ventral nerve cord. Human ortholog(s) of this gene implicated in congenital dyserythropoietic anemia type IV. Orthologous to human KLF1 (Kruppel like factor 1); KLF14 (Kruppel like factor 14); and KLF16 (Kruppel like factor 16). [provided by Alliance of Genome Resources, Apr 2022]

Huckebein is part of a combinatorial repression code in the anterior blastoderm.
Title: Huckebein is part of a combinatorial repression code in the anterior blastoderm.
hkb(gurt) mutant embryos reveal that the adjacent endoderm plays a critical role in the later stages of visceral muscle development
Title: Fusion of circular and longitudinal muscles in Drosophila is independent of the endoderm but further visceral muscle differentiation requires a close contact between mesoderm and endoderm.
hkb plays a role in salivary tube development in Drosophila
Title: Epithelial tube morphology is determined by the polarized growth and delivery of apical membrane.
Huckebein does not activate transcription; rather, it physically interacts with Glide/Gcm thereby triggering its autoregulation.
Title: Huckebein-mediated autoregulation of Glide/Gcm triggers glia specification.
