Family: Clathrin (PF00637)

Summary: Region in Clathrin and VPS

Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.

The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.

This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.

Region in Clathrin and VPS Provide feedback

Each region is about 140 amino acids long. The regions are composed of multiple alpha helical repeats. They occur in the arm region of the Clathrin heavy chain.

InterPro entry IPR000547

Proteins synthesized on the ribosome and processed in the endoplasmic reticulum are transported from the Golgi apparatus to the trans-Golgi network (TGN), and from there via small carrier vesicles to their final destination compartment. These vesicles have specific coat proteins (such as clathrin or coatomer) that are important for cargo selection and direction of transport [PUBMED:15261670]. Clathrin coats contain both clathrin (acts as a scaffold) and adaptor complexes that link clathrin to receptors in coated vesicles. Clathrin-associated protein complexes are believed to interact with the cytoplasmic tails of membrane proteins, leading to their selection and concentration. The two major types of clathrin adaptor complexes are the heterotetrameric adaptor protein (AP) complexes, and the monomeric GGA (Golgi-localising, Gamma-adaptin ear domain homology, ARF-binding proteins) adaptors [PUBMED:17449236, PUBMED:11598180].

Clathrin is a trimer composed of three heavy chains and three light chains, each monomer projecting outwards like a leg; this three-legged structure is known as a triskelion [PUBMED:15752139, PUBMED:16806884]. The heavy chains form the legs, their N-terminal beta-propeller regions extending outwards, while their C-terminal alpha-alpha-superhelical regions form the central hub of the triskelion. Peptide motifs can bind between the beta-propeller blades. The light chains appear to have a regulatory role, and may help orient the assembly and disassembly of clathrin coats as they interact with hsc70 uncoating ATPase [PUBMED:16734666]. Clathrin triskelia self-polymerise into a curved lattice by twisting individual legs together. The clathrin lattice forms around a vesicle as it buds from the TGN, plasma membrane or endosomes, acting to stabilise the vesicle and facilitate the budding process [PUBMED:15261670]. The multiple blades created when the triskelia polymerise are involved in multiple protein interactions, enabling the recruitment of different cargo adaptors and membrane attachment proteins [PUBMED:16699812].

This entry represents the 7-fold alpha-alpha-superhelical ARM-type repeat found at the C-terminal of clathrin heavy chains and in VPS (vacuolar protein sorting-associated) proteins. In clathrin heavy chains, the C-terminal 7-fold ARM-type repeats interact to form the central hub of the triskelion. VPS proteins are required for vacuolar assembly and vacuolar traffick, and contain one clathrin-type repeat [PUBMED:14745133].

More information about these proteins can be found at Protein of the Month: Clathrin [PUBMED:].

Alignments

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database using the family HMM. We also generate alignments using four representative proteomes (RP) sets, the NCBI sequence database, and our metagenomics sequence database. More...

View options

We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

MyHits provides a collection of tools to handle multiple sequence alignments. For example, one can refine a seed alignment (sequence addition or removal, re-alignment or manual edition) and then search databases for remote homologs using HMMER3.

Trees

This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.

Note: You can also download the data file for the tree.

Structures

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the Clathrin domain has been found. There are 51 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
