Gag Polyprotein (None)

Target
None
Molecular classification
Structural protein, Viral protein, Polyprotein
01

Overview

The Gag polyprotein is indispensable for retroviral replication due to its multifaceted roles in assembling new virus particles at cellular membranes, recruiting/packaging genomes via specific domains/interactions with both viral/cellular factors, mediating release through engagement with ESCRT machinery—and finally undergoing precise cleavage events that transform non-infectious precursors into mature infectious virions. Its structure-function relationships are highly conserved among retroviruses such as HIV.
