Background: HIV-1 Gag p24

The gag gene of human immunodeficiency virus 1 (HIV-1) encodes a precursor protein known as Pr55Gag. The viral protease PR cleaves this precursor to generate p17, p24, p7, and p6 proteins which are required for virus particle assembly. p24 is a major viral core structural protein. Its measurement is commonly used as an indicator of HIV-1 infection and viral load.

Long Name:
Human Immunodeficiency Virus Type 1 GAG/Group-specific Antigen core protein of 24 kDa
Entrez Gene IDs:
155030 (Viral)
Alternate Names:
CA; Capsid Protein; HIV1 Gag p24; HIV-1 Gag p24; Pr55(Gag)
