Witryna1 maj 2003 · It is shown that the RNA-DNA hybrid structure that forms in vitro is an R-loop with a displaced guanine (G)-rich strand that is single-stranded that exists in vivo in B cells that have been stimulated to transcribe theγ3 or the γ2b switch region. The mechanism responsible for immunoglobulin class switch recombination is unknown. … Witryna1 lip 2010 · Ab class switch recombination involves a recombination between two repetitive DNA sequences known as switch (S) regions that vary in length, content, …
Witryna8 mar 2005 · Immunoglobulin class switch recombination joins a new constant (C) region to the rearranged and expressed heavy chain variable (VDJ) region in antigen-activated B cells (Figure 1A) (reviewed in [1, 2]). Switch recombination is activated by transcription of intronic, G-rich and repetitive switch (S) … WitrynaImmunoglobulin D (IgD) is an antibody ... Alternative splicing is promoted in all jawed vertebrates but class switch recombination only in higher vertebrates and increase diversification of IgD. In jawed fishes, the structure of the constant region is highly diverse with amplifications of Cδ exons. Different splice variants exists due to ...
