[[http://www.uniprot.org/uniprot/MU1_REOVL MU1_REOVL]] Major outer capsid protein involved in host cell membrane penetration. In the endocytic compartment, outer-capsid protein sigma-3 is removed by cathepsin proteases, which exposes the viral membrane-penetration protein mu-1. Both myristoylated peptides mu-1N and phi are released during infectious subvirion particles (ISVP) formation in the endosome. They associate with host membranes and mu-1N induces permeabilization and delivery of transcriptionally active viral particles into the host cell cytoplasm. Seems to induce apoptosis in the host cell.<ref>PMID:11007773</ref> <ref>PMID:15280481</ref> <ref>PMID:16912293</ref> <ref>PMID:17005655</ref> <ref>PMID:18369316</ref>  The viral outer shell polypeptides, of which mu-1 is one, impose structural constraints that prevent elongation of nascent transcripts by the RNA-dependent RNA polymerase lambda-3.<ref>PMID:11007773</ref> <ref>PMID:15280481</ref> <ref>PMID:16912293</ref> <ref>PMID:17005655</ref> <ref>PMID:18369316</ref>
