A1 cistron-splicing factor AAR2 - P32357 (AAR2_YEAST)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Number of PDB entries for P32357: 7
Component of the U5 snRNP complex that is required for spliceosome assembly and for pre-mRNA splicing. Involved in splicing pre-mRNA of the A1 cistron and other genes that are important for cell growth. (data source: UniProt  )
Subunit structure
Heterodimer (Probable). Interacts with PRP8 (via RNase H homology domain and MPN domain), competing with BRR2 for the same binding site. Component of a U5 snRNP complex that contains at least the U5 snRNA, PRP8, SNU114, AAR2, SMB1, SMD1, SMD2, SMD3, SME1, SMX2 and SMX3, but is not a component of the U4/U6-U5 tri-snRNP complex. (data source: UniProt  )

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
Data in red indicates combined ranges of Homology Models from SBKB   and the Protein Model Portal  

The PDB to UniProt mapping is based on the data provided by the EBI SIFTS project. See also Velankar et al., Nucleic Acids Research 33, D262-265 (2005).
