Figure 1. Variation in the relative abundance of the two forms of the HLA-A 3’UTR.

Figure 1

RNA was obtained from peripheral blood lymphocytes of healthy donors. Rapid amplification of cDNA ends (3’ RACE) of 3’UTRs of HLA-A alleles from 6 individuals with distinct HLA-A genotypes showed preferential use of either the proximal or distal PAS. HLA-A*01 and A*11 use only the proximal PAS, resulting in the short form of the 3’UTR, whereas others use various fractions of each. HLA-A genotypes of the individuals are indicated below each amplicon.
