Latest Patents

Nefsky's latest patents focus on the discovery of ubiquitin ligases in eukaryotic cells. These proteins, collectively referred to as "pub" proteins, include h-pub1, h-pub2, and s-pub1. His research indicates that pub1 proteins play a crucial role in the ubiquitination of the mitotic activating tyrosine phosphatase cdc25. This process is essential for regulating cell proliferation by activating cyclin-dependent kinase complexes. Disruption of s-pub1 leads to elevated levels of cdc25 protein, which increases the activity of tyrosine kinases, wee1 and mik1, necessary for cell-cycle arrest. The loss of wee1 function in cells with disrupted s-pub1 results in a lethal premature entry into mitosis, a phenotype that can be rescued by the loss of cdc25 function.
