Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Centrosomal protein required in the positioning and anchorage of the microtubule minus-end in epithelial cells (PubMed:15190203, PubMed:23386061). May also act as a centrosome maturation factor (PubMed:11956314). May play a role in microtubule nucleation, by recruiting the gamma-tubulin ring complex to the centrosome (PubMed:15190203). Overexpression does not perturb nucleation or elongation of microtubules but suppresses release of microtubules (PubMed:15190203). Required for centriole organization and microtubule anchoring at the mother centriole (PubMed:23386061). UniProt

Subunit Structure
Homooligomer. Interacts with GSK3B/GSK3-beta via its C-terminal domain (PubMed:11004522). Interacts with C14ORF166, such interaction may prevent its phosphorylation by GSK3B (PubMed:15147888). Interacts with AUNIP (via N-terminus) (PubMed:20596670). Identified in a complex with AUNIP and AURKA (PubMed:20596670). Interacts with CCDC120 (PubMed:28422092). Interacts (via C-terminus) with CEP250 (By similarity). Interacts with CEP170 (By similarity). Interacts with the gamma-tubulin ring complex component TUBGCP3 (By similarity). Interacts with gamma-tubulin (By similarity). Isoform 6 does not interact with CEP170 or CEP250 (By similarity). UniProt
Domain
The N-terminal domain is important for targeting to the mother centriole, although it is not sufficient by itself for centrosomal localization. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
