**Background of Recombinant Human MKKS Protein**
The McKusick-Kaufman syndrome (MKKS) gene encodes a chaperonin-like protein crucial for cellular protein folding and assembly. Initially linked to McKusick-Kaufman syndrome, a rare autosomal recessive disorder characterized by congenital anomalies, MKKS was later found to associate with Bardet-Biedl syndrome (BBS), a ciliopathy affecting multiple organs. The MKKS protein operates as part of the BBSome complex, regulating ciliary function and intracellular trafficking. Its dysfunction disrupts cilia-mediated signaling pathways, leading to developmental defects, retinal degeneration, obesity, and renal abnormalities.
Recombinant human MKKS protein is engineered in vitro using expression systems like *E. coli* or mammalian cells, enabling functional studies on its structural and mechanistic roles. Research focuses on its interaction with BBS proteins, cilia assembly, and substrate recognition. Structural analyses reveal conserved domains critical for binding co-chaperones and facilitating protein quality control. Recombinant MKKS also aids in modeling disease-causing mutations, offering insights into pathogenesis and potential therapeutics. By studying its role in cellular homeostasis and ciliopathies, scientists aim to develop targeted therapies for MKKS-related disorders, emphasizing its dual function as a chaperone and ciliary regulator in human health and disease.
