Retroviral nucleocapsid protein Gag (IPR000721)

Short name: Gag_p24

Family relationships

None.

Description

The Gag protein from retroviruses, also known as p24, forms the inner protein layer of the nucleocapsid. This protein performs highly complex orchestrated tasks during the assembly, budding, maturation and infection stages of the viral replication cycle. During viral assembly, the proteins form membrane associations and self-associations that ultimately result in budding of an immature virion from the infected cell. Gag precursors also function during viral assembly to selectively bind and package two plus strands of genomic RNA. ELISA tests for p24 is the most commonly used method to demonstrate virus replication both in vivo and in vitro.
