Interactioni

Subunit structurei

Part of a stable entry-fusion complex (EFC) which is at least composed of proteins A16, A21, A28, G3, G9, H2, J5, and L5. Formation of the viral membrane is necessary for the assembly of the complex. Interacts with A16; this heterodimer further interact with A56/K2 fusion regulatory heterodimer (By similarity).By similarity
