Autophagy-related protein 13 - O75143 (ATG13_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Autophagy factor required for autophagosome formation and mitophagy. Target of the TOR kinase signaling pathway that regulates autophagy through the control of the phosphorylation status of ATG13 and ULK1, and the regulation of the ATG13-ULK1-RB1CC1 complex. Through its regulation of ULK1 activity, plays a role in the regulation of the kinase activity of mTORC1 and cell proliferation. UniProt

Subunit Structure
Part of a complex consisting of ATG13, ULK1 and RB1CC1 (PubMed:19597335, PubMed:19211835, PubMed:19225151, PubMed:24290141). Interacts with ATG101 (PubMed:19597335, PubMed:19287211, PubMed:26299944). Interacts with ULK1 (via C-terminus); this interaction is increased in the absence of TMEM39A (PubMed:19287211, PubMed:21855797, PubMed:18936157, PubMed:31806350). Interacts with ULK2 (via C-terminus) (PubMed:19225151, PubMed:18936157). Interacts (via the LIR motif) with GABARAP, GABARAPL, GABARAPL2 (PubMed:23043107). Interacts (via the LIR motif) with MAP1LC3A, MAP1LC3B and MAP1LC3C (PubMed:24290141). Interacts with TAB2 and TAB3 (PubMed:21976705). Interacts with C9orf72 (PubMed:27334615). Interacts with RB1CC1; this interaction is increased in the absence of TMEM39A (PubMed:31806350). UniProt
The LIR motif (LC3-interacting region) is required for the interaction with the ATG8 family proteins GABARAP, GABARAPL, GABARAPL2, and MAP1LC3A. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
