The Ugandan cassava brown streak virus (UCBSV) coat
protein is a capsid protein, responsible for the encapsulation of
the viral RNA genome and entry into the host cell. Unlike the coat
protein in Cassava brown streak virus, the coat protein
for UCBSV does not contain a DAG motif (aspartic
acid-alanine-glycine), which is associate with aphid-mediated
transmission. The full length protein is roughly 43 kDa in size.
