GRINA (Glia Derived Nexin): GRINA is a protein that serves as a key component of the central nervous system, particularly involved in neuroprotection and the regulation of neuronal excitability. It interacts with NMDA (N-methyl-D-aspartate) receptors, which are crucial for synaptic plasticity, memory formation, and learning. GRINA’s function is tied to its ability to modulate these receptors, affecting neurodevelopment and neural response mechanisms. Dysregulation of GRINA has been linked to neurological disorders such as Alzheimer’s disease, epilepsy, and schizophrenia.
