Protein

Gag-Pro polyprotein

Gene

gag-pro

Organism
Rous sarcoma virus (strain Prague C) (RSV-PrC)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Capsid protein p27 forms the spherical core of the virus that encapsulates the genomic RNA-nucleocapsid complex.By similarity
The aspartyl protease mediates proteolytic cleavages of Gag and Gag-Pol polyproteins during or shortly after the release of the virion from the plasma membrane. Cleavages take place as an ordered, step-wise cascade to yield mature proteins. This process is called maturation. Displays maximal activity during the budding process just prior to particle release from the cell.PROSITE-ProRule annotation

Domaini

Late-budding domains (L domains) are short sequence motifs essential for viral particle release. They can occur individually or in close proximity within structural proteins. They interacts with sorting cellular proteins of the multivesicular body (MVB) pathway. Most of these proteins are class E vacuolar protein sorting factors belonging to ESCRT-I, ESCRT-II or ESCRT-III complexes. P2B contains one L domain: a PPXY motif which probably binds to the WW domains of HECT (homologous to E6-AP C-terminus) E3 ubiquitin ligases (By similarity).By similarity
