The neuronal class 2 TSR proteins F-spondin and Mindin: a small family with divergent biological activities

Feinstein, Yael, Klar, Avihu·2004·The International Journal of Biochemistry & Cell Biology

Abstract

F-spondin and Mindin are members of a subgroup of the thrombospondin type 1 (TSR) class molecules, defined by two domains of homology, the FS1/FS2 and TSR domains. The TSRs of F-spondin proteins are typical of class 2 TSRs. F-spondin and Mindin are evolutionarily conserved proteins. The embryonic expression of the vertebrate genes is enriched in the nervous system, mainly at the floor plate and the hippocampus. Similar to thrombospondin, F-spondin and Mindin are extracellular matrix attached molecules that promote neurite outgrowth and inhibit angiogenesis. Analysis of gain and loss of function experiments reveal that F-spondin is required for accurate pathfinding of embryonic axons. F-spondin plays a dual role in patterning axonal trajectories: it promotes the outgrowth of commissural and inhibits the outgrowth of motor axons. Macrophages of Mindin-deficient mice exhibit defective responses to a broad spectrum of microbial stimuli. This may implicate Mindin and F-spondin in inflammatory processes in the nervous system.

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.
