Recombinant Human SKA2 Protein

Product Name: Recombinant Human SKA2 Protein
Catalog #:  HRP-1467
Manufacture:  LD Biopharma, Inc.

Human spindle and kinetochore-associated protein 2 (SKA2) is a component of the SKA1 complex, a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation. Required for timely anaphase onset during mitosis, when chromosomes undergo bipolar attachment on spindle microtubules leading to silencing of the spindle checkpoint. The SKA1 complex is a direct component of the kinetochore-microtubule interface and directly associates with microtubules as oligomeric assemblies. The complex facilitates the processive movement of microspheres along a microtubule in a depolymerization-coupled manner. In the complex, it is required for SKA1 localization. Recent data indicated that SKA2 might influence suicidal phenotypes through its role in chaperoning the glucocorticoid receptor from cytoplasm to the nucleus.

Full-length mature human SKA2 cDNA (121aa) was constructed with fully codon optimization strategy and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
