**Background of PICK1 Recombinant Protein**
PICK1 (Protein Interacting with C Kinase 1) is a cytosolic scaffolding protein encoded by the *PICK1* gene, first identified for its ability to bind protein kinase Cα (PKCα). It belongs to the PDZ domain-containing protein family and plays a critical role in regulating synaptic plasticity, receptor trafficking, and intracellular signaling. Structurally, PICK1 contains an N-terminal PDZ domain, which mediates interactions with transmembrane proteins (e.g., AMPA receptors, dopamine transporters), and a C-terminal BAR (Bin/Amphiphysin/Rvs) domain, enabling membrane curvature sensing and dimerization.
PICK1 is highly expressed in the brain, particularly in neurons, where it facilitates the clustering and trafficking of postsynaptic receptors (e.g., GluA2 subunits of AMPA receptors) and presynaptic neurotransmitter transporters. Its function is closely tied to synaptic strength modulation, impacting learning and memory. Dysregulation of PICK1 has been implicated in neurological and psychiatric disorders, including Parkinson’s disease, Alzheimer’s disease, schizophrenia, and drug addiction.
Recombinant PICK1 proteins are engineered in vitro using expression systems (e.g., *E. coli*, mammalian cells) to study its biochemical properties, structure-function relationships, and interactions with binding partners. These purified proteins enable researchers to explore mechanisms underlying PICK1-mediated trafficking, screen for therapeutic compounds targeting PICK1-associated pathways, and model disease-related mutations.
Overall, PICK1 recombinant proteins serve as essential tools for unraveling its physiological roles and potential as a therapeutic target in neuropathologies.
