Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

Matrix protein p16 forms the outer shell of the core of the virus, lining the inner surface of the viral membrane.By similarity
Capsid protein p26 forms the conical core of the virus that encapsulates the genomic RNA-nucleocapsid complex. Interaction between incoming particle-associated Gag proteins and host dynein allows intracellular microtubule-dependent virus transport toward the perinuclear region, prior to nucleus translocation and integration into host genome.1 Publication
Nucleocapsid protein p13 encapsulates and protects viral dimeric unspliced (genomic) RNA. Binds these RNAs through its zinc fingers (By similarity).By similarity

Miscellaneous

The sequence shown is that of isolate R29-127.

Late-budding domains (L domains) are short sequence motifs essential for viral particle budding. They recruit proteins of the host ESCRT machinery (Endosomal Sorting Complex Required for Transport) or ESCRT-associated proteins. Gag polyprotein contains one L domain: a PTAP/PSAP motif, which interacts with the UEV domain of TSG101 (By similarity).By similarity
