Tracking a frameshift through the ribosome

Ribosomes, the factories that assemble proteins in cells, read three letters of messenger RNA at a time. Occasionally, the ribosome can bend its rules, and read either two or four nucleotides, altering how downstream information is read: frameshifting.

Christine Dunham’s lab in the Department of Biochemistry has a paper in PNAS on how ribosomal frameshifting works, one of several she has published on this topic. The first author is postdoc Samuel Hong, now at MD Anderson.

Dr. Dunham is a faculty member in the BCDB, MMG and MSP programs.
