How antibodies fold

Open access
Feige, Matthias J., Hendershot, Linda M., Buchner, Johannes·2010·Trends in Biochemical Sciences

Abstract

B cells use unconventional strategies for the production of a seemingly unlimited number of antibodies from a very limited amount of DNA. These methods dramatically increase the likelihood of producing proteins that cannot fold or assemble appropriately. B cells are therefore particularly dependent on 'quality control' mechanisms to oversee antibody production. Recent in vitro experiments demonstrate that Ig domains have evolved diverse folding strategies ranging from robust spontaneous folding to intrinsically disordered domains that require assembly with their partner domains to fold; in vivo experiments reveal that these different folding characteristics form the basis for cellular checkpoints in Ig transport. Taken together, these reports provide a detailed understanding of how B cells monitor and ensure the functional fidelity of Ig proteins.

  • Correct folding of scFv and Fab fragments is highly dependent on the activity of PPIases.

    “In particular, the correct folding of scFv and Fab fragments has been found to be highly dependent on the activity of PPIases [162].”

    From Evolution of Escherichia coli Expression System in Producing Antibody Recombinant Fragments (2020) · cites this paper as [162]

    The section ‘From the folding of antibody domains to complete IgG molecules’ (page unavailable) says that proline isomerization is rate-limiting for CH1 folding and relates this step to Fab folding. The concluding remarks also say that peptidyl-prolyl isomerization controls antibody folding. Neither passage establishes that correct folding of both scFv and Fab fragments is highly dependent on PPIase enzyme activity; a requirement for isomerization is not itself evidence of dependence on those enzymes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
