ADF/Cofilin: a functional node in cell biology

Open access
Bernstein, Barbara W., Bamburg, James R.·2010·Trends in Cell Biology

Abstract

Recent findings have significantly expanded our understanding of the regulation of actin-depolymerizing factor (ADF)/cofilin proteins and the profound multifaceted impact that these well-established regulators of actin dynamics have on cell biology. In this review we discuss new aspects of previously documented regulation, such as phosphorylation, but also cover novel recently established modes of regulation and functions of ADF (also known as destrin)/cofilin. We now understand that their activity responds to a vast array of inputs far greater than previously appreciated and that these proteins not only feed back to the crucially important dynamics of actin, but also to apoptosis cascades, phospholipid metabolism, and gene expression. We argue that this ability to respond to physiological changes by modulating those same changes makes the ADF/cofilin protein family a homeostatic regulator or 'functional node' in cell biology.

  • The diffusion of WT and S3A cofilin, but not S3E cofilin, in the resting state was significantly impeded by their binding to F-actins.

    “These findings suggest that the diffusion of WT or S3A cofilin, but not S3E cofilin, was significantly impeded by their binding to F-actins1326.”

    From State-dependent diffusion of actin-depolymerizing factor/cofilin underlies the enlargement and shrinkage of dendritic spines (2016) · cites this paper as [13]

    The ‘Phosphorylation of Ser3’ section states that Ser3 phosphorylation inhibits cofilin binding to F-actin, and the pH-regulation section identifies S3A as a mutant that cannot be inactivated by phosphorylation (page numbers unavailable). These passages support the proposed binding distinction, but the paper does not report diffusion measurements or the claimed significant difference among WT, S3A and S3E cofilin in resting cells. (LLM, conf=0.83)

  • Cofilin is a highly abundant actin-regulatory protein that binds to and alters the physical properties of F-actin.

    “Cofilin is a highly abundant actin-regulatory protein, which binds to and alters the physical properties of F-actin1314.”

    From State-dependent diffusion of actin-depolymerizing factor/cofilin underlies the enlargement and shrinkage of dendritic spines (2016) · cites this paper as [13]

    The Modulation of actin dynamics section says cofilin regulates actin filaments and, when bound at high ratios, stabilizes F-actin in a twisted form. The Distribution section calls cofilin-1 the most ubiquitous form, but does not establish that cofilin is highly abundant; ubiquity is not the same as abundance. Page numbers are unavailable in our copy. (LLM, conf=0.83)

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.
