Microglia/macrophage‐specific protein Iba1 binds to fimbrin and enhances its actin‐bundling activity
Abstract
Ionized calcium binding adaptor molecule 1 (Iba1) is a microglia/macrophage‐specific calcium‐binding protein. Iba1 has the actin‐bundling activity and participates in membrane ruffling and phagocytosis in activated microglia. In order to understand the Iba1‐related intracellular signalling pathway in greater detail, we employed a yeast two‐hybrid screen to isolate an Iba1‐interacting molecule and identified another actin‐bundling protein, L‐fimbrin. In response to stimulation, L‐fimbrin accumulated and co‐localized with Iba1 in membrane ruffles induced by M‐CSF‐stimulation and phagocytic cups formed by IgG‐opsonized beads in microglial cell line MG5. L‐fimbrin was shown to associate with Iba1 in cell lysate of COS‐7 expressing L‐fimbrin and Iba1. By using purified proteins, direct binding of Iba1 to L‐fimbrin was demonstrated by immunoprecipitation, glutathione S‐transferase pull‐down assays and ligand overlay assays. The binding of Iba1 was also found to increase the actin‐bundling activity of L‐fimbrin. These results indicate that Iba1 forms complexes with L‐fimbrin in membrane ruffles and phagocytic cups, and suggest that Iba1 co‐operates with L‐fimbrin in modulating actin reorganization to facilitate cell migration and phagocytosis by microglia.

“Although Iba1 possesses actinbundling activity, the amino acid sequence of Iba1 displays no homology to the CH domain (Imai et al. 1996; Sasaki et al. 2001).”

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.
