The pre-integration complex (PIC) is a nucleoprotein complex of viral genetic material and associated viral and host proteins. The PIC forms after uncoating of a viral particle after entry into the host cell. In the case of the human immunodeficiency virus (HIV), the PIC consists of viral proteins (including Vpr, matrix and integrase), host proteins (including Barrier to autointegration factor 1) and two strands of the ribonucleic acid (RNA) genome. Within the HIV PIC, the process of reverse transcription converts the viral RNA genome into double-stranded DNA (dsDNA). The PIC enters the cellular nucleus through the nuclear pore complex without disrupting the nuclear envelope, thus allowing HIV and related retroviruses to replicate in non-dividing cells.^[1]^[2] Following nuclear entry, the PIC's DNA payload may be integrated into the host DNA as a "provirus".^[3]
