Phospho-PTPN6 (Tyr564)

Full Name

Function

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.

Cellular Location

Cytoplasm
Nucleus
In neurons, translocates into the nucleus after treatment with angiotensin II (By similarity).
Shuttles between the cytoplasm and nucleus via its association with PDPK1

PTM

Phosphorylated on tyrosine residues. Binding of KITLG/SCF to KIT increases tyrosine phosphorylation (By similarity).
Phosphorylation at Tyr-564 enhances phosphatase activity.
