The motifs are mostly from retroviral gag proteins (nucleocapsid). Prototype structure is from HIV. Also contains members involved in eukaryotic gene regulation, such as C. elegans GLH-1. Structure is an 18-residue zinc finger.

The PTAP motif interacts with the cellular budding factor TSG101 [1]. This domain is also found in some chimpanzee immunodeficiency virus (SIV-cpz) proteins.
