TMEM25 Protein, crucial in neurons, modulates the degradation of the NMDA receptor GRIN2B subunit, influencing the intricate regulation of neuronal excitability. Its interaction with GRIN2B highlights its role in dynamic processes central to neurotransmission and synaptic function. TMEM25 Protein, Human (HEK293, His) is the recombinant human-derived TMEM25 protein, expressed by HEK293 , with C-His labeled tag.
