Sister chromatid cohesion protein 1 - Q12158 (SCC1_YEAST)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q12158: 2
Cleavable component of the cohesin complex involved in chromosome cohesion during cell cycle. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At metaphase-anaphase transition, this protein is cleaved by ESP1 and dissociates from chromatin, allowing sister chromatids to segregate. (data source: UniProt  )
Subunit structure
Interacts directly with IRR1/SCC3 in cohesin complex. Cohesin complexes are composed of the SMC1 and SMC3 heterodimer attached via their hinge domain, MCD1/SCC1 which link them, and IRR1, which interacts with MCD1. The cohesin complex also interacts with SCC2, which is required for its association with chromosomes. (data source: UniProt  )
The C-terminal part associates with the head of SMC1, while the N-terminal part binds to the head of SMC3. (data source: UniProt  )
Organism (common name): Baker's yeast
Other Gene names: MCD1 PDS3 RHC21 SCC1 YDL003W YD8119.04

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 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
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).
