Abstract

Activation of the c-Jun NH(2)-terminal kinase (JNK) group of mitogen-activated protein (MAP) kinases is mediated by a protein kinase cascade. This signaling mechanism may be coordinated by the interaction of components of the protein kinase cascade with scaffold proteins. The JNK-interacting protein (JIP) group of scaffold proteins selectively mediates signaling by the mixed-lineage kinase (MLK)-->MAP kinase kinase 7 (MKK7)-->JNK pathway. The scaffold proteins JIP1 and JIP2 interact to form oligomeric complexes that accumulate in peripheral cytoplasmic projections extended at the cell surface. The JIP proteins function by aggregating components of a MAP kinase module (including MLK, MKK7, and JNK) and facilitate signal transmission by the protein kinase cascade.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • MAPK scaffolding proteins JIP1 and PEA-15 and substrates RSK1, MK2, and MEF2a also contain a linear KIM domain that mediates MAPK binding in the cell.

    “Notably, MAPK scaffolding proteins (JNK-interacting protein, JIP1; 29 phosphoprotein enriched in astrocytes 15, PEA-15 30 ) and substrates (Ribosomal protein S6 kinase alpha-1, RSK1; 31 MAP kinase-activated protein kinase 2, MK2; 32 and myocyte enhancer factor 2A, MEF2a 33 ) also contain linear KIM domain, which mediates MAPK binding in the cell.”

    From Molecular basis of MAP kinase regulation (2013) · cites this paper as [29]

  • JIPs display a highly polarized subcellular localization at the tips of neuronal cell processes and in extended projections from the surface of insulinoma cells.

    “The JIPs display a highly polarized subcellular localization at the tips of neuronal cell processes and in extended projections from the surface of insulinoma cells (Meyer et al. 1999; Yasuda et al. 1999; Kelkar et al. 2000).”
  • JIP-1 and JIP-2 are ∼50% identical, have a similar domain structure, and can form homodimeric and heterodimeric complexes.

    “JIP-1 (also known as IB1) and JIP-2 are ∼50% identical, have a similar domain structure, and can form homodimeric and heterodimeric complexes (Yasuda et al. 1999).”

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.
