Illuminating the Dark Zone
MCDB scientists make new discoveries about a specific protein and its effects on the final step of cell division. A new study conducted by in the laboratory of Zach Ma in MCDB reveals a novel function for WDR5, a protein known for its critical role in gene expression whereby information encoded in genes is converted into products like RNA (ribonucleic acid) and protein. In cells, WDR5 is a subunit of a five-protein complex. Mutations in members of this complex can result in childhood leukemia and other disorders affecting numerous organ systems in the body. The UCSB team worked with WDR5 in cultured human cell lines. The results of the study appear in the Journal of Biological Chemistry.
