The UspA2 protein has been shown to be directly involved in the serum-resistant phenotype of Moraxella catarrhalis. The predicted 5'-untranslated regions (UTR) of the uspA2 genes in several different M. catarrhalis strains were shown to contain various numbers (i.e., 6 to 23) of a heteropolymeric tetranucleotide (AGAT) repeat. Deletion of the AGAT repeats from the uspA2 genes in the serum-resistant M. catarrhalis strains O35E and O12E resulted in a drastic reduction in UspA2 protein expression… CONTINUE READING
