**Background of Recombinant Human VAX1 Protein**
Ventral anterior homeobox 1 (VAX1) is a transcription factor belonging to the homeobox gene family, which plays critical roles in embryonic development, particularly in the formation of the forebrain, visual system, and craniofacial structures. It regulates gene expression during neurogenesis, optic nerve development, and midline facial patterning. Recombinant human VAX1 protein is a lab-engineered version produced using genetic engineering techniques, often expressed in bacterial or mammalian systems to ensure proper folding and functionality.
Studies highlight VAX1's involvement in neural crest cell migration and differentiation, as well as its interaction with signaling pathways like SHH (Sonic Hedgehog) and FGF (Fibroblast Growth Factor). Mutations or dysregulation of VAX1 are linked to congenital defects, including holoprosencephaly, optic nerve hypoplasia, and craniofacial abnormalities. Its recombinant form enables researchers to study molecular mechanisms, protein-DNA interactions, and pathway modulation in vitro or in vivo.
Structurally, VAX1 contains a conserved homeodomain for DNA binding and transcriptional regulation. Research tools like recombinant VAX1 antibodies or tagged proteins aid in elucidating its role in developmental disorders and potential therapeutic targets. Ongoing research focuses on its applications in developmental biology, disease modeling, and regenerative medicine.
