**Background of Recombinant Human TBCD Protein**
Recombinant human TBCD (tubulin folding cofactor D) is a molecular chaperone critical for the proper folding and assembly of α/β-tubulin heterodimers, essential components of microtubules. In vivo, TBCD works synergistically with other cofactors (TBCA-TBCE) to guide β-tubulin through a ATP-dependent folding pathway, ensuring structural integrity and functional competency. It also plays a regulatory role in microtubule dynamics by promoting the disassembly of misfolded tubulin, thereby maintaining cellular homeostasis.
Dysregulation of TBCD is linked to neurodevelopmental disorders, such as encephalopathy and cortical dysplasia, underscoring its importance in brain development. Recombinant TBCD, typically produced in *E. coli* or mammalian expression systems, allows researchers to study tubulin biogenesis mechanisms, dissect disease pathways, and explore therapeutic targets. Its applications extend to *in vitro* reconstitution of tubulin folding, drug screening for microtubule-related diseases (e.g., cancer, neurodegeneration), and functional studies of pathogenic mutations. The engineered protein retains native biochemical properties, enabling precise manipulation of tubulin-microtubule cycles in controlled settings, thus advancing both basic and translational research in cell biology and medicine.
