Gosset African Swine Fever Virus p54 Protein Overview
The African swine fever virus (ASFV) p54 protein is a critical structural and functional component of the ASFV virion. It is encoded by the E183L gene and has a molecular weight of approximately 25 kDa. The protein is classified as a type I transmembrane protein, localizing predominantly to the external envelope of the virus and associating with endoplasmic reticulum (ER)-derived membranes during viral assembly. It is essential for recruitment and transformation of ER membranes into viral envelope precursors, facilitating intracellular transport of viral capsids. It also plays a role in virus attachment to target cells. p54 is highly immunogenic, inducing neutralizing antibodies upon infection or immunization and is considered a potential vaccine candidate.
