| Research Abstract |
The affinity of antibodies for antigens is improved by somatic hypermutation (SHM) occurred on the immunoglobulin (Ig) gene. In this study, using the hypermutating chicken B cell line DT40, we found that an isoform of the alternative-splicing factor ASF/SF2, ASF3 is essential for SHM on the Ig gene. The results also suggest that ASF3 might have a role in the activation and targeting of the mutation machinery through the regulation of post-transcriptional processing on the Ig gene.
