Gag polyprotein - P14349 (GAG_FOAMV)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Involved in capsid formation and genome binding. Shortly after infection, interaction between incoming particle-associated Gag proteins and host dynein allows centrosomal targeting of the viral genome (associated to Gag), prior to nucleus translocation and integration into host genome. UniProt

Subunit Structure
Gag protein specifically interacts with the N-terminus of leader peptide (By similarity). This specific interaction between Gag protein and Env glycoprotein may compensate for the lack of a Gag membrane targeting signal, and allow particle egress. The capsid is composed of multimeric Gag protein. Interacts with human TSG101. Interacts with host light chain cytoplasmic dynein DYNLL1; this interaction is critical for intracellular microtubule-dependent viral genome transport toward the centrosome. UniProt
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. Nucleocapsid protein p14 contains one L domain: a PTAP/PSAP motif, which interacts with the UEV domain of TSG101. UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
