Pleiotrophin: Activity and mechanism

Abstract

Pleiotrophin (PTN) is a potent mitogenic cytokine with a high affinity for the polysaccharide glycosaminoglycan (GAG). Although it is most strongly associated with neural development during embryogenesis and the neonatal period, its expression has also been linked to a plethora of other physiological events including cancer metastasis, angiogenesis, bone development, and inflammation. A considerable amount of research has been carried out to understand the mechanisms by which PTN regulates these events. In particular, PTN has now been shown to bind a diverse collection of receptors including many GAG-containing proteoglycans. These interactions lead to the activation of many intracellular kinases and, ultimately, activation and transformation of cells. Structural studies of PTN in complex with both GAG and domains from its non-proteoglycan receptors reveal a binding mechanism that relies on electrostatic interactions and points to PTN-induced receptor oligomerization as one of the possible ways PTN uses to control cellular functions.

  • The Ptn-Ncl interaction facilitates internalization of the Ptn-Ncl complex.

    “This interaction facilitates the internalization of the Ptn-Ncl complex [Wang, 2020].”

    From Cell signaling pathways discovery from multi-modal data (2025) · cites this paper as Wang, 2020

    The Nucleolin section (page unavailable) says cell-surface nucleolin interacts with PTN and presents its delivery of PTN into the nucleus as a hypothesis. The Structure of PTN section likewise says intracellular localization may result from their interaction. These passages support a possible transport role, but do not establish that the interaction facilitates internalization of a PTN–nucleolin complex. (LLM, conf=0.84)

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.
