詳細

詳細

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.

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.[1][2]

生物化学的／生理学的作用

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.[2][3]

調製ノート

氷上で解凍してください。最初に解凍した際、チューブを軽く遠心して内容物を完全に回収してください。酵素液は一回の使用量ずつ分注してください。分注した酵素液は希釈せずそのまま-70°Cで保存してください。注:酵素は凍結融解の繰り返しに対して非常に不安定です。
