CC   -!- FUNCTION: Plays a crucial role in virion assembly and budding.
CC       Expressed late in the virus life cycle, it acts as an inhibitor of
CC       viral transcription and RNA synthesis by interacting with the viral
CC       polymerase L. Presumably recruits the NP encapsidated genome to
CC       cellular membranes at budding sites via direct interaction with NP.
CC       Plays critical roles in the final steps of viral release by interacting
CC       with host TSG101, a member of the vacuolar protein-sorting pathway and
CC       using other cellular host proteins involved in vesicle formation
CC       pathway. The budding of the virus progeny occurs after association of
CC       protein Z with the viral glycoprotein complex SSP-GP1-GP2 at the cell
CC       periphery, step that requires myristoylation of protein Z. Also
CC       selectively represses protein production by associating with host
CC       eIF4E. {ECO:0000255|HAMAP-Rule:MF_04087, ECO:0000269|PubMed:12970423}.
CC   -!- SUBUNIT: Interacts with protein NP; this interaction probably directs
CC       the encapsidated genome to budding sites. Interacts (via RING domain)
CC       with polymerase L; this interaction inhibits viral transcription and
CC       replication. Interacts with the glycoprotein complex; this interaction
CC       plays a role in virion budding. Interacts with host eIF4E; this
CC       interaction results in eIF4E reduced affinity for its substrate, the
CC       5'-m7 G cap structure. Interacts (via late-budding domain) with host
CC       TSG101; this interaction is essential for budding and release of viral
CC       particles. Interacts with host RPLP0; this interaction may serve to
CC       load ribosome-like particles inside the virion. Interacts with host
CC       PML; this interaction induces PML bodies redistribution in the
CC       cytoplasm upon viral infection. {ECO:0000255|HAMAP-Rule:MF_04087,
CC       ECO:0000269|PubMed:12970423}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04087}. Host
CC       cytoplasm, host perinuclear region {ECO:0000255|HAMAP-Rule:MF_04087}.
CC       Host cell membrane {ECO:0000255|HAMAP-Rule:MF_04087}; Lipid-anchor
CC       {ECO:0000255|HAMAP-Rule:MF_04087}; Cytoplasmic side {ECO:0000255|HAMAP-
CC       Rule:MF_04087}. Note=Mainly perinuclear. During budding, associates at
CC       the inner side of the plasma membrane of infected cells.
CC       {ECO:0000255|HAMAP-Rule:MF_04087}.
CC   -!- DOMAIN: Late-budding domains (L domains) are short sequence motifs
CC       essential for viral particle budding. They recruit proteins of the host
CC       ESCRT machinery (Endosomal Sorting Complex Required for Transport) or
CC       ESCRT-associated proteins. {ECO:0000255|HAMAP-Rule:MF_04087}.
CC   -!- SIMILARITY: Belongs to the arenaviridae Z protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04087}.
