Extended Data Figure 2. Ectopic TIRR restores RAD51 foci formation in BRCA1-mutant MEFs.
a, Brca1-mutant MEFs stably transduced with an empty vector (EV) or TIRR-FH were transfected with the indicated siRNA. RAD51 was stained six hours after 5 Gy irradiation (mean ± s.d., n=3). b, Quantification of CSR at 96h or 72h post-stimulation from splenic B cells transduced with pMIG or pMIG-TIRR, and stimulated with LPS and IL-4 for 72 h. c, AID, Sμ germline (Sμ GLT) and Sγ1 germline (Sγ1 GLT, black) transcripts in splenic B cells stimulated for 48 h (mean ± s.d., n=3 mice). d, Immunoblotting of AID and TIRR from lysates prepared from splenic B cells stimulated for 72 h.
