Abstract

A 145-kDa tyrosine-phosphorylated protein that becomes associated with Shc in response to multiple cytokines has been purified from the murine hemopoietic cell line B6SUtA1. Amino acid sequence data were used to clone the cDNA encoding this protein from a B6SUtA1 library. The predicted amino acid sequence encodes a unique protein containing an N-terminal src homology 2 domain, two consensus sequences that are targets for phosphotyrosine binding domains, a proline-rich region, and two motifs highly conserved among inositol polyphosphate 5-phosphatases. Cell lysates immunoprecipitated with antiserum to this protein exhibited both phosphatidylinositol 3,4,5-trisphosphate and inositol 1,3,4,5-tetrakisphosphate polyphosphate 5-phosphatase activity. This novel signal transduction intermediate may serve to modulate both Ras and inositol signaling pathways. Based on its properties, we suggest the 145-kDa protein be called SHIP for SH2-containing inositol phosphatase.

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.
