Recombinant human GRIK1 protein is a genetically engineered form of the glutamate ionotropic receptor kainate type subunit 1. a key component of kainate receptors (KARs) in the central nervous system. These receptors, a subclass of ionotropic glutamate receptors, mediate fast excitatory neurotransmission and modulate synaptic plasticity. GRIK1 (encoded by the *GRIK1* gene) assembles with other subunits (e.g., GRIK4/5) to form functional KARs, which influence neuronal excitability, learning, and memory. Dysregulation of GRIK1 is linked to neurological disorders, including epilepsy, schizophrenia, and autism spectrum disorders.
The recombinant protein is typically produced in mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications and ligand-binding activity. It retains the structural and functional properties of native GRIK1. enabling studies on receptor pharmacology, subunit interactions, and signal transduction mechanisms. Researchers use recombinant GRIK1 to screen therapeutic compounds targeting KARs, investigate disease-associated mutations, and explore its role in synaptic pathology. Its availability accelerates drug discovery and mechanistic insights into glutamate receptor-related diseases.
