CC   -!- FUNCTION: The Vlp and Vsp proteins are antigenically distinct proteins,
CC       only one vlp or vsp gene is transcriptionally active at any one time.
CC       Switching between these genes is a mechanism of host immune response
CC       evasion. {ECO:0000250|UniProtKB:P21875}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane
CC       {ECO:0000250|UniProtKB:P21875}; Lipid-anchor.
CC   -!- MISCELLANEOUS: Genes for both Vlp and Vsp families are on (usually)
CC       unnamed linear plasmids in B.hermsii HS1. {ECO:0000305|PubMed:9453591}.
CC   -!- SIMILARITY: Belongs to the variable small protein (Vsp) family.
CC       {ECO:0000269|PubMed:9453591}.
