**Background of TBX4 Recombinant Protein**
TBX4. a member of the T-box transcription factor family, plays critical roles in embryonic development, particularly in limb formation, lung branching morphogenesis, and vascular system regulation. It binds to specific DNA sequences via its conserved T-box domain, modulating the expression of target genes involved in cell differentiation, proliferation, and tissue patterning. Mutations in the *TBX4* gene are linked to congenital disorders such as small patella syndrome and pulmonary arterial hypertension (PAH), highlighting its importance in human health.
Recombinant TBX4 protein is engineered using biotechnological platforms (e.g., bacterial or mammalian expression systems) to produce a purified, functional form of the protein for research and therapeutic applications. This involves cloning the *TBX4* gene into expression vectors, optimizing conditions for protein synthesis, and employing affinity chromatography (e.g., His-tag purification) to ensure high purity and stability.
In research, recombinant TBX4 is widely used to investigate molecular mechanisms underlying developmental pathways, including fibroblast growth factor (FGF) and bone morphogenetic protein (BMP) signaling. It also serves as a tool for disease modeling, drug screening, and gene therapy studies targeting TBX4-associated disorders. Additionally, its potential in regenerative medicine, such as promoting tissue repair or guiding stem cell differentiation, is being explored.
Overall, TBX4 recombinant protein provides a valuable resource for decoding developmental biology and advancing translational applications in genetic and pulmonary diseases.
