Latest Patents
Kaku's latest patent focuses on a groundbreaking method for producing protein. It has long been understood that enhancing the assembly of polysomes, which are complexes of many ribosomes attached to mRNA, is critical for highly efficient protein synthesis. However, the precise mechanism by which p180 protein promotes polysome formation remained unclear. Kaku's research led to the discovery of SF3b4 protein, which specifically interacts with the coiled-coil domain of p180 protein. This interaction is essential for mRNA localization to the endoplasmic reticulum (ER).
Furthermore, Kaku and his team found that in cells expressing high levels of both p180 and SF3b4 protein, mRNA localization to the ER can be significantly improved, thereby enhancing the secretory capacity in cultured cells. They demonstrated that inserting a specific nucleotide sequence into an expression plasmid enables SF3b4 protein, which enhances protein expression, to be localized on the ER membrane. This strategic localization shifts the mRNA distribution within polysomes toward heavier fractions, ultimately boosting the secretory capacity of the cells.
