CC   -!- FUNCTION: Promotes tail assembly by creating a scaffold for the tail
CC       tube proteins. Tail assembly proteins E and E' would wrap the linear
CC       tape measure protein to create a tail assembly scaffold. {ECO:0000305}.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Ribosomal frameshifting; Named isoforms=2;
CC       Name=Tail assembly protein E';

CC       Name=Tail assembly protein E;
CC         IsoId=O64313-1; Sequence=External;
CC   -!- MISCELLANEOUS: [Isoform Tail assembly protein E']: Produced by -1
CC       ribosomal frameshift. {ECO:0000269|PubMed:12426340}.
CC   -!- SIMILARITY: Belongs to the mulikevirus tail assembly protein family.
