Genetic and structural analysis of polyomavirus BK T-antigens reveal a higher density of mutations at inter-domain and hexamerization regions, regardless the status of infection.

Abstract excerpt

Polyomavirus BK (BKPyV) T-antigens (large and small tumor antigens, or Lt-ag and st-ag, respectively), control key aspects of viral replication and are able to regulate cell cycle, promoting cell proliferation. However, the structural effects of genetic mutations on T-antigens are poorly investigated. In this study, 214 sequences of T-antigens from individuals with different BKPyV infections (16 renal transplant...
