Clathrin heavy chain 1 - Q00610 (CLH1_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Clathrin is the major protein of the polyhedral coat of coated pits and vesicles. Two different adapter protein complexes link the clathrin lattice either to the plasma membrane or to the trans-Golgi network. Acts as component of the TACC3/ch-TOG/clathrin complex proposed to contribute to stabilization of kinetochore fibers of the mitotic spindle by acting as inter-microtubule bridge (PubMed:15858577, PubMed:16968737, PubMed:21297582). The TACC3/ch-TOG/clathrin complex is required for the maintenance of kinetochore fiber tension (PubMed:23532825). Plays a role in early autophagosome formation (PubMed:20639872). UniProt

Subunit Structure
Clathrin triskelions, composed of 3 heavy chains and 3 light chains, are the basic subunits of the clathrin coat (PubMed:16968737). In the presence of light chains, hub assembly is influenced by both the pH and the concentration of calcium. Interacts with HIP1 (PubMed:11532990). Interacts with DENND1A, DENND1B and DENND1C (By similarity). May interact with OCRL (By similarity). Interacts with ERBB2 (PubMed:16314522). Interacts with FKBP6 (PubMed:18529014). Interacts with CKAP5 and TACC3 forming the TACC3/ch-TOG/clathrin complex located at spindle inter-microtubules bridges; the complex implicates clathrin triskelions; TACC3 and CLTC are proposed to form a composite microtubule interaction surface (PubMed:21297582). Interacts with ATG16L1 (via N-terminus) (PubMed:20639872). Interacts with RFTN1; the interaction occurs in response to pathogens (PubMed:27022195, PubMed:21266579). Interacts with USP2 isoform 4 (PubMed:26756164). UniProt
The N-terminal seven-bladed beta-propeller is formed by WD40-like repeats, and projects inward from the polyhedral outer clathrin coat. It constitutes a major protein-protein interaction node. 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.
