HIV-1 entry to macrophages and CD4 + T cells is mediated through interaction of the virion envelope glycoproteins (gp120) with the CD4 molecule on the target cells and also with chemokine coreceptors. Source: Internet
The budded virion is still immature as the gag polyproteins still need to be cleaved into the actual matrix, capsid and nucleocapsid proteins. Source: Internet
Purified RNA of a negative-sense virus is not infectious by itself as it needs to be transcribed into positive-sense RNA; each virion can be transcribed to several positive-sense RNAs. Source: Internet
It functions in proteolytic cleavages during virion maturation to make mature gag and pol proteins. Source: Internet
However, it is still not entirely clear whether the L and M proteins are part of the virion. Source: Internet
Protein names and their copy numbers in the virion particle are shown. Source: Internet
