P12 is a cleavage product from the murine leukaemia virus (MLV) Gag protein and is essential for various steps in viral replication and during both early and late stages of murine leukaemia virus (MLV) infection.
The N- and C-terminal regions of p12 are sequentially acting domains, both required for p12 function. The N-terminal domain of p12 binds directly to the MLV capsid protein (CA), thus stabilising the capsid shell and viral core. p12 contains the PPPY late-domain (L-domain), which is essential for recruiting HECT ubiquitin ligases which regulate pathways to ensure efficient budding.
