12. Panel C shows the translational products of the HIV gag–pol gene and the sites at which the gene product is cleaved by the virus-encoded protease. p17 denotes capsid protein, p24 matrix protein, and p7 nucleocapsid; p2, p1, and p6 are small proteins with unknown functions. The arrows denote cleavage events catalyzed by the HIV-specific protease. Protease Inhibitors Protease action
