Histone chaperone ASF1 - P32447 (ASF1_YEAST)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P32447: 8
 
Function
Histone chaperone that facilitates histone deposition and histone exchange and removal during nucleosome assembly and disassembly. Facilitates histone deposition through both replication-dependent and replication-independent chromatin assembly pathways. Cooperates with chromatin assembly factor 1 (CAF-1) to promote replication-dependent chromatin assembly and with the HIR complex to promote replication-independent chromatin assembly, which may occur during transcription and DNA repair. May be required for the maintenance of a subset of replication elongation factors, including DNA polymerase epsilon, the RFC complex and PCNA, at stalled replication forks. Also required for acetylation of histone H3 on 'Lys-9' and 'Lys-56'. UniProt

Subunit Structure
Interacts with histone H3/H4 heterodimers via both histone H3 and histone H4. Interacts with RAD53 and this may impair interaction with histones and chromatin assembly. Interaction with RAD53 is reduced upon activation of DNA damage or replication checkpoints and loss of RAD53 may in turn facilitate interaction with histones and chromatin assembly. Interacts with the CAC2 subunit of chromatin assembly factor 1 (CAF-1). Interacts with the HIR1, HIR2, HIR3 and HPC2 subunits of the HIR complex. Interacts with the RFC1, RFC2, RFC3, RFC4 and RFC5 subunits of the replication factor C (RF-C/RFC) complex. The RF-C complex may recruit this protein to DNA. Interacts with the SAS2, SAS4 and SAS5 subunits of the SAS/SAS-I complex. Interacts with the BDF1, BDF2, SPT15, TAF1 and TAF7 subunits of the TFIID complex. Interacts with RTT109. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
