Mouse ACP3/PAP (Prostatic Acid Phosphatase) ELISA Kit

ACPP,also known as prostatic acid phosphatase,belongs to the histidine acid phosphatase family. It has phosphotyrosyl phosphatase activity. It is predominantly expressed in the prostate gland,and restricted to gladular and ductal epithelial cells,and mainly in the secreted form. It is also widely expressed in non-prostatic tissues,such as bladder,kidney,pancreas,lung,cervix,testis,and ovary,as a type I transmembrane protein with N-terminal phosphatase activity. The expression of ACPP correlates with prostate cell proliferation. High levels of ACPP leads to slow cell growth. Though the level of ACPP in the circulation is increased in prostate cancer patients,its level and activity are reduced in prostate cancer cells. ACPP serves as a tumor suppressor. Reduced ACPP levels result in hyperphosphorylation of HER-2 (human epidermal growth factor receptor-2),activating downstream MAPK signaling,prostate cancer progression and androgen-independent growth. In addition,ACPP dephosphorylates ErbB-2,blocking downstream ERK1/2 and AKT signaling and tumorigenicity.Gene AliasACP3Gene ID56318Uniport IDQ8CE08Protein AliasACP3Research AreaCancer,Cell Biology Protein function: A non-specific tyrosine phosphatase that dephosphorylates a diverse number of substrates under acidic conditions (pH 4-6) including alkyl, aryl, and acyl orthophosphate monoesters and phosphorylated proteins. Has lipid phosphatase activity and inactivates lysophosphatidic acid in seminal plasma. [The UniProt Consortium]
