ALIX-binding late domains often contain the core consensus sequence: "YPXnL" (where Xn can vary in sequence and length). However, some SIV Gag proteins lack this consensus sequence, yet still bind ALIX. We mapped divergent, ALIX-binding late domains within the p6(Gag) proteins of SIVmac239 (40SREKPYKEVTEDLLHLNSLF59) and SIVagmTan-1 (24AAGAYDPARKLLEQYAKK41). Crystal structures revealed that anchoring tyrosines (bold) and nearby hydrophobic residues (underlined) contact the ALIX V domain, revealing how lentiviruses employ a diverse family of late domain sequences to bind ALIX and promote virus budding.
