**Background of Recombinant Human TTC7B Protein**
The TTC7B (Tetratricopeptide Repeat Domain 7B) protein is a member of the tetratricopeptide repeat (TPR) family, characterized by structural TPR motifs that facilitate protein-protein interactions. It plays a regulatory role in cellular processes, including membrane trafficking, cell cycle progression, and apoptosis. Human TTC7B is encoded by the *TTC7B* gene, located on chromosome 14q32.12. and shares homology with TTC7A, a protein linked to immune dysregulation.
Functionally, TTC7B interacts with the kinase PI4KIIIα (phosphatidylinositol 4-kinase III alpha) and EFR3 homolog B, forming part of a complex critical for phosphatidylinositol 4-phosphate synthesis, which is essential for Golgi apparatus function and intracellular signaling. Dysregulation of TTC7B has been implicated in diseases such as inflammatory disorders and cancers. Notably, mutations in *TTC7B* are associated with X-linked idiopathic congenital neutropenia and myelofibrosis, highlighting its role in hematopoiesis.
Recombinant human TTC7B protein, produced via expression systems like *E. coli* or mammalian cells, enables functional studies, including its interaction networks, enzymatic activity, and structural analysis. Its recombinant form is instrumental in exploring therapeutic targets, particularly for diseases linked to TPR protein dysfunction. Research continues to uncover its broader biological roles, including potential involvement in autophagy and immune response pathways.
