Background

​​PTP4A3 (Protein Tyrosine Phosphatase 4A3)​​ is an oncogenic phosphatase that promotes tumor metastasis by enhancing cell migration, invasion, and survival. It is overexpressed in multiple cancers (e.g., breast, ovarian, colorectal) and correlates with poor prognosis. PTP4A3 activates Rho GTPases and downstream pathways (ROCK/LIMK/cofilin) to remodel the actin cytoskeleton, facilitating cancer cell dissemination. Its dual cysteine-based catalytic domain dephosphorylates key signaling proteins, driving aggressive phenotypes. Targeting PTP4A3 offers therapeutic potential for inhibiting metastasis.
