Immunoglobulin heavy chain mutation status
WitrynaImmunoglobulin Class Switching. Ig class switching in Xenopus is a component of the secretory immune response and is associated with AT-rich switch boxes, which exhibit sequence changes (insertions, deletions, mutations) in regions of predicted secondary structure (Mussmann et al., 1996).

WitrynaIgA is the most abundant antibody in mammals. However, the mechanism of its class switching is still not clear. The formation of the R-loops, as the target for AID, has been proposed to play a crucial role during mammalian class switch recombination.
