Rabbit anti-Human PTP4A3 Polyclonal Antibody

Uniprot Id

O75365

Target Species

Human

Target Name

PTP4A3

Target Full Name

Protein tyrosine phosphatase type IVA 3

Target Function

Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. Enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis. May be involved in the progression of cardiac hypertrophy by inhibiting intracellular calcium mobilization in response to angiotensin II.

Target Subcellular Location

Cell membrane. Early endosome.

Target Protein Families

Protein-tyrosine phosphatase family

Target Tissue Specificity

Mainly expressed in cardiomyocytes and skeletal muscle; also found in pancreas. Consistently overexpressed in colon cancer metastasis.

Target Synonyms

Potentially prenylated protein tyrosine phosphatase; PRL 3; PRL R; PRL-3; PRL-R; PRL3; PRLR; Protein tyrosine phosphatase 4a3; Protein tyrosine phosphatase type IVA 3; Protein-tyrosine phosphatase 4a3; Protein-tyrosine phosphatase of regenerating liver 3; PTP 4A3; PTP4A3; TP4A3_HUMAN

Target Background

This gene encodes a member of the protein-tyrosine phosphatase family. Protein tyrosine phosphatases are cell signaling molecules that play regulatory roles in a variety of cellular processes. Studies of this class of protein tyrosine phosphatase in mice demonstrates that they are prenylated in vivo, suggesting their association with cell plasma membrane. The encoded protein may enhance cell proliferation, and overexpression of this gene has been implicated in tumor metastasis. Alternative splicing results in multiple transcript variants.
