. "FUNCTION Matrix protein p17 targets Gag and Gag-Pol polyproteins to the plasma membrane via a multipartite membrane binding signal, that includes its myristoylated N-terminus. Also mediates nuclear localization of the preintegration complex. Implicated in the release from host cell mediated by Vpu.FUNCTION Capsid protein p24 forms the conical core of the virus that encapsulates the genomic RNA-nucleocapsid complex.FUNCTION Nucleocapsid protein p7 encapsulates and protects viral dimeric unspliced (genomic) RNA. Binds these RNAs through its zinc fingers.PTM Specific enzymatic cleavages by the viral protease yield mature proteins. The polyprotein is cleaved during and after budding, this process is termed maturation.MISCELLANEOUS The MN isolate was taken from a pediatric AIDS patient in 1984.MISCELLANEOUS HIV-1 lineages are divided in three main groups, M (for Major), O (for Outlier), and N (for New, or Non-M, Non-O). The vast majority of strains found worldwide belong to the group M. Group O seems to be endemic to and largely confined to Cameroon and neighboring countries in West Central Africa, where these viruses represent a small minority of HIV-1 strains. The group N is represented by a limited number of isolates from Cameroonian persons. The group M is further subdivided in 9 clades or subtypes (A to D, F to H, J and K).SIMILARITY Belongs to the primate lentivirus group gag polyprotein family.SIMILARITY Contains 2 CCHC-type zinc fingers."^^ . .
