| Function of HIV Genes HIV consists of nine genes. Three of the genes provide genetic information for the capsid proteins, envelope proteins, and viral enzymes. The other six genes are regulatory genes, controlling functions such as uncoating of the HIV genome and the penetration of host cells.

| Penetration and Infection After penetration of the cell membrane by the gp41, the HIV capsid enters the cell's cytoplasm. Next, cellular enzymes strip away the capsid so that the HIV genome is released. Also stripped away are proteins p24 and p17. Protein 24 coats the HIV genome and protein 17 lines the inside of the capsid. | View Page |
