'''CRYSTAL STRUCTURE OF THE COMPLEX FORMED BETWEEN THE CATALYTIC DOMAIN OF SHP-1 AND AN IN VITRO PEPTIDE SUBSTRATE PY469 DERIVED FROM SHPS-1.'''<br />

==CRYSTAL STRUCTURE OF THE COMPLEX FORMED BETWEEN THE CATALYTIC DOMAIN OF SHP-1 AND AN IN VITRO PEPTIDE SUBSTRATE PY469 DERIVED FROM SHPS-1.==
The substrate specificity of the catalytic domain of SHP-1, an important, regulator in the proliferation and development of hematopoietic cells, is, critical for understanding the physiological functions of SHP-1. Here we, report the crystal structures of the catalytic domain of SHP-1 complexed, with two peptide substrates derived from SIRPalpha, a member of the, signal-regulatory proteins. We show that the variable beta5-loop-beta6, motif confers SHP-1 substrate specificity at the P-4 and further, N-terminal subpockets. We also observe a novel residue shift at P-2, the, highly conserved subpocket in protein- tyrosine phosphatases. Our, observations provide new insight into the substrate specificity of SHP-1.

== Function ==
[https://www.uniprot.org/uniprot/PTN6_HUMAN PTN6_HUMAN] Modulates signaling by tyrosine phosphorylated cell surface receptors such as KIT and the EGF receptor/EGFR. The SH2 regions may interact with other cellular components to modulate its own phosphatase activity against interacting substrates. Together with MTUS1, induces UBE2V2 expression upon angiotensin II stimulation. Plays a key role in hematopoiesis.<ref>PMID:11266449</ref>

The substrate specificity of the catalytic domain of SHP-1, an important regulator in the proliferation and development of hematopoietic cells, is critical for understanding the physiological functions of SHP-1.

We show that the variable beta5-loop-beta6 motif confers SHP-1 substrate specificity at the P-4 and further N-terminal subpockets. We also observe a novel residue shift at P-2, the highly conserved subpocket in protein- tyrosine phosphatases. Our observations provide new insight into the substrate specificity of SHP-1.
