DNA repair protein crb2 - P87074 (RHP9_SCHPO)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P87074: 5
 
Function
Essential for cell cycle arrest at the G1 and G2 stages following DNA damage by X-, and UV-irradiation, or inactivation of DNA ligase. Plays a role in the response to DNA damage (PubMed:9153313, PubMed:9407031). Interaction with rad4 via its phosphorylation sites in the N-terminus couples the DNA checkpoint apparatus to chromatin via interaction of its C-terminal BRCT domains with epigenetic modifications on histones H4 and H2A, respectively, in the G1/S phase of the cell cycle, and facilitates recruitment of the checkpoint kinase chk1 (PubMed:15550243, PubMed:16778077, PubMed:18826944, PubMed:20679485, PubMed:22792081).

Subunit Structure
Homodimer. Dimerization is mediated via the BRCT domain (PubMed:16778077, PubMed:18676809). Interacts (via BRCT domain) with rad3 (PubMed:14739927). Interacts with rad4 (via BRCT1,2 domains) (PubMed:9407031, PubMed:14739927); a single rad4 molecule interacts simultaneously with both Thr-187 phosphorylation sites in a crb2 dimer (PubMed:24074952). Interacts (via Tudor domain) with histone H4K20me2 (PubMed:18826944, PubMed:17190600). Interacts (via BRCT dmain) with histone H2AS128ph (gamma-H2A) (PubMed:20679485, PubMed:18676809). Interacts with chk1 (PubMed:9407031, PubMed:14739927, PubMed:22792081). Interacts with sad1 (PubMed:14655046). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
