Improved methodology for protein NMR structure calculation using hydrogen bond restraints and ANSURR validation: The SH2 domain of SH2B1.

This sequence corresponds to residues 519-628 from mouse SH2B1 (Uniprot Q91ZM2)
with the addition of a 9-residue His tag at the N terminus.
Thus the first included residue of the mouse sequence (D519) is Asp-10.

Binds to phosphotyrosine, eg in the JAK2 kinase
