535:, a highly conserved and ubiquitously expressed cell surface receptor for extracellular matrix proteins. Dystroglycan, which is later cleaved into alpha-dystroglycan and beta-dystroglycan is originally expressed in most cells to mature tissues, and it provides molecular link between the ECM and the actin-based cytoskeleton. After the virus enters the cell by alpha-dystroglycan mediated endocytosis, the low-pH environment triggers pH-dependent membrane fusion and releases RNP (viral ribonucleoprotein) complex into the cytoplasm. Viral RNA is unpacked, and replication and transcription initiate in the cytoplasm. As replication starts, both S and L RNA genomes synthesize the 597: 68: 512: 335: 38: 406: 3107: 3095: 547:. The S RNA encodes GP and NP (viral nucleocapsid protein) proteins, while L RNA encodes Z and L proteins. The L protein most likely represents the viral RNA-dependent RNA polymerase. When the cell is infected by the virus, L polymerase is associated with the viral RNP and initiates the transcription of the genomic RNA. The 5’ and 3’ terminal 19 nt viral 464:
