L1R

L1R, the recombinant vaccinia virus L1 protein, comes from the Vaccinia virus genome and is produced through recombinant genetic engineering. It plays a crucial role in the viral life cycle, serving as one of the primary proteins for viral entry into host cells and participating in the fusion of viral and cellular membranes. L1R's mechanism involves binding to host cell receptors, facilitating the entry of the viral particle core into the cytoplasm. This protein is vital for understanding the pathogenesis of poxviruses and for developing antiviral drugs and vaccines.
