2 Figure 1 Alternative Splicing of CD45
Alternative splicing of exons 4, 5, and 6 in naive T cells permits the inclusion of heavily glycosylated segments A, B, and C, respectively, in CD45 cell-surface protein. Variable amounts of high molecular weight isoforms, including RABC, RAB, RBC, and RB are detected on the surface of naive T cells. Upon differentiation to memory T cells, upregulation of hnRNPLL inhibits splicing and inclusion of exons 4, 5, and 6, generating predominantly the short isoform CD45RO.
