Background :
Phosphatases of regenerating liver (PRL-1, PRL-2, and PRL-3, also known as PTP4A1, PTP4A2, and PTP4A3) control magnesium homeostasis through an association with the CNNM magnesium transport regulators. PRL-1 (PTP4A1) is a key molecule that activates tyrosine phosphorylation, which is important for cancer progression and metastasis.
Synonyms :
PTP4A1; PTP(CAAXI); PRL-1; PRL1; PTPCAAX1;
