SARS-CoV-2 (Delta) S protein RBD , hFc Tag

Recombinant SARS-CoV-2 RBD(L452R,T478K) protein with C-terminal human Fc tag. S protein RBD(L452Rand T487K)(Arg319-Phe541) hFc(Glu99-Ala330), Protein function: Packages the positive strand viral genome RNA into a helical ribonucleocapsid (RNP) and plays a fundamental role during virion assembly through its interactions with the viral genome and membrane protein M. Plays an important role in enhancing the efficiency of subgenomic viral RNA transcription as well as viral replication. May modulate transforming growth factor-beta signaling by binding host smad3.
