基本信息
| NACRES | NA.32 |
| General description【一般描述】 | Protein-tyrosine-phosphatase of regenerating liver 1 (PRL1), also known as protein tyrosine phosphatase type IVA, member 1 (PTP4A1), is encoded by the gene mapped to human chromosome 6q12. The encoded protein is a member of a small class of prenylated protein tyrosine phosphatases (PTPs). It is characterized by a PTP domain and a specific C-terminal prenylation motif. PRL1 is mainly localized to the cell membrane and the endoplasmic reticulum depending on its C-terminal prenylation. Human PRL 1 (GenBank Accession No. BC023975), (amino acids 2-173) with N-terminal HIS tag, MW = 19.8 kDa, expressed in an E. coli expression system. |
| Application【应用】 | Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. |
| Biochem/physiol Actions【生化/生理作用】 | Protein-tyrosine-phosphatase of regenerating liver 1 (PRL1) or protein tyrosine phosphatase type IVA, member 1 (PTP4A1) regulates cancer-related signaling pathways, which are downstream of epidermal growth factor receptor (EGFR) pathway and stimulates cell proliferation, invasion and migration. PRL1 acts as a potential therapeutic target and predictor for patient survival in prostate cancer (PCa) including those with castration-resistant prostate cancer (CRPC). PRL1 is essential for normal mitotic process. Elevated expressions of prenylated protein tyrosine phosphatases (PTPs) in mammalian cells conferred a transformed phenotype, which might be involved in the tumorigenesis. |
