Securin-like protein - Q18235 (IFY1_CAEEL)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q18235: 1
Acts as a chaperone and as an inhibitor for separase sep-1 (PubMed:27249343, PubMed:28263324). Plays an essential role in maintaining chromosome cohesion prior to meiotic and mitotic anaphase, in cytokinesis and in organizing the spindle and the centrosome (PubMed:12498686). Ubiquitination-dependent degradation at the onset of anaphase is likely to activate sep-1 resulting in the proteolysis of the cohesin complex and the subsequent segregation of the chromosomes (PubMed:12498686, PubMed:23578927). Also required for cortical granule exocytosis (PubMed:17913784). UniProt

Subunit Structure
Forms a complex (via C-terminus) with separase sep-1 (PubMed:12498686, PubMed:23578927, PubMed:27249343, PubMed:28263324). Interaction with ify-1 stabilizes sep-1 (PubMed:27249343, PubMed:28263324). Also maintains the complex in the cytoplasm during interphase and recruits it to chromosomes during the first meiotic division (PubMed:23578927). Interacts with E3 ubiquitin-protein ligase etc-1 (PubMed:23578927). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
