**注意**:若您的研究对象确为“PRL2A1”,建议:
1. 核对基因/蛋白命名(如是否指代PRL2亚型或数据库录入差异);
2. 扩展检索词(如“PRL2 recombinant”、“Phosphatase of regenerating liver 2”);
3. 查阅专利数据库或特定物种(如斑马鱼PRL2A1可能命名不同)。
PRL2A1 (Phosphatase of Regenerating Liver 2A1) is a member of the PRL phosphatase family, which includes three isoforms (PRL-1. PRL-2. and PRL-3) sharing a conserved protein tyrosine phosphatase (PTP) catalytic domain. These phosphatases are implicated in cellular processes such as proliferation, migration, and metastasis, often through interactions with signaling pathways like PI3K/AKT and MAPK. PRL2A1. encoded by the PTP4A2 gene, is distinct for its oncogenic potential. Overexpression of PRL2A1 has been observed in multiple cancers, including breast, colorectal, and liver malignancies, where it correlates with tumor progression and poor prognosis. Its enzymatic activity, targeting phosphotyrosine residues, is critical for regulating downstream substrates involved in cell cycle control and invasion.
Recombinant PRL2A1 protein is engineered using expression systems (e.g., E. coli, mammalian cells) to produce a purified, biologically active form for functional studies. The recombinant protein typically retains the conserved PTP domain and may include tags (e.g., His-tag) for purification and detection. Structural studies reveal a compact fold stabilized by disulfide bonds, with a catalytic cysteine essential for phosphatase activity. Researchers utilize recombinant PRL2A1 to investigate its role in cancer mechanisms, screen inhibitory compounds, or analyze substrate interactions. Its application extends to disease models, where modulating PRL2A1 activity helps validate its therapeutic targeting potential. Despite progress, questions remain about its precise substrates and context-dependent regulatory roles, driving ongoing research into its pathophysiological significance.
