这些研究涵盖了AAK1重组蛋白的结构解析、药物开发及功能多样性方向，为理解其生物学作用及疾病治疗提供了依据。
AAK1 (Adaptor-Associated Protein Kinase 1) is a serine/threonine kinase belonging to the Ark1/Prk1 kinase family, primarily recognized for its role in regulating clathrin-mediated endocytosis (CME). It phosphorylates components of the AP-2 adaptor complex, a critical step in facilitating receptor-ligand internalization and vesicle formation. Beyond its canonical function in membrane trafficking, AAK1 has been implicated in diverse physiological and pathological processes, including neuronal signaling, viral entry, and cancer progression. Its dual regulatory capacity—governing both endocytic machinery and cellular signaling pathways—underscores its biological versatility.
Recombinant AAK1 protein is engineered through heterologous expression systems (e.g., bacterial, insect, or mammalian cells) to produce purified, functional kinase for research and therapeutic development. The recombinant form typically retains the kinase domain and regulatory regions, enabling in vitro studies on enzymatic activity, substrate interactions, and inhibitor screening. Tags such as GST or His are often incorporated to facilitate purification and detection.
Interest in AAK1 has surged due to its therapeutic potential. It interacts with viral entry mechanisms, notably supporting hepatitis C virus (HCV) infection by phosphorylating host proteins required for viral trafficking. Consequently, AAK1 inhibitors are explored as broad-spectrum antivirals. In neurology, AAK1 modulates neuropathic pain pathways and neurotransmitter receptor dynamics, linking it to chronic pain and neurodegenerative disorders like Alzheimer’s. In oncology, AAK1 overexpression correlates with tumor growth and metastasis, potentially through Notch and Wnt signaling dysregulation.
Pharmaceutical efforts targeting AAK1 focus on selective small-molecule inhibitors (e.g., SGC-AAK1-1) to minimize off-target effects against its homolog GAK. Structural studies using recombinant AAK1 have elucidated kinase-ligand binding modes, guiding drug design. Additionally, recombinant protein-based assays remain pivotal for high-throughput screening and mechanistic studies, positioning AAK1 as a multifunctional kinase with expanding translational relevance.
