| Outline of Final Research Achievements |
In this study, we analyzed molecular mechanisms for SRSF1-3 to contribute to somatic hypermutation of the IgV gene. It is revealed that although isoforms SRSF1 and SRSF1-3 are different only in the C-terminal region, the C-terminal region of SRSF1-3 is not essential for SHM, suggesting that the conserved region might be involved in SHM. In addition, this study indicated that SRSF1-3 may have a role in regulating the nuclear export of AID during SHM processes.
