Abstract

The adapter protein Shc has been implicated in mitogenic signaling via growth factor receptors, cytokine receptors, and antigen receptors on lymphocytes. Besides the well characterized interaction of Shc with molecules involved in Ras activation, Shc also associates with a 145-kDa tyrosine-phosphorylated protein upon triggering via antigen receptors and many cytokine receptors. This 145-kDa protein has been recently identified as an SH2 domain containing 5'-inositol phosphatase (SHIP) and has been implicated in the regulation of growth and differentiation in hematopoietic cells. In this report, we have addressed the molecular details of the interaction between Shc and SHIP in vivo. During T cell receptor signaling, tyrosine phosphorylation of SHIP and its association with Shc occurred only upon activation. We demonstrate that the phosphotyrosine binding domain of Shc is necessary and sufficient for its association with tyrosine-phosphorylated SHIP. Through site-directed mutagenesis, we have identified two tyrosines on SHIP, Tyr-917, and Tyr-1020, as the principal contact sites for the Shc-phosphotyrosine binding domain. Our data also suggest a role for the tyrosine kinase Lck in phosphorylation of SHIP. We also show that the SH2 domain of SHIP is dispensable for the Shc-SHIP interaction in vivo. These data have implications for the localization of the Shc.SHIP complex and regulation of SHIP function during T cell receptor signaling.

  • Phosphorylation at Tyr1022 within the NPxY motif allows SHIP1 to bind PTB domain-containing proteins.

    “while phosphorylation at Tyr1022 (Tyr1020 in mice) within the NPxY motif allows SHIP1 to bind PTB domain-containing proteins [111, 112], as well as SHIP1’s own SH2 domain [113].”

    From Microglial function, INPP5D/SHIP1 signaling, and NLRP3 inflammasome activation: implications for Alzheimer’s disease (2023) · cites this paper as [111]

    The Tyr-917/Tyr-1020 binding experiments and conclusion (Fig. 4; page not provided) show that phosphorylation of SHIP Tyr-1020 contributes to binding the PTB domain of Shc. The paper does not establish the human Tyr-1022 numbering or binding to PTB domain-containing proteins beyond Shc. (LLM, conf=0.86)

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.
