The CD64 protein is a high-affinity receptor for the immunoglobulin gamma Fc region and plays a key role in innate and adaptive immune responses. It prevents FCGR1A degradation by interacting with FCERG1 and FLNA to form a functional signaling complex. CD64 Protein, Rabbit (HEK293, His) is the recombinant Rabbit-derived CD64 protein, expressed by HEK293 , with C-His labeled tag.
