| Functional site class: | Clathrin box |
| Functional site description: | Clathrin boxes are found on cargo adaptor proteins. They interact with the N-terminal beta-propeller structure of Clathrin heavy chain. Beside the "classical" motif, some variants have been described for various types of adaptor proteins. The same protein can bear several subtypes of Clathrin boxes. |
| ELMs with same func. site: | LIG_Clathr_ClatBox_1 LIG_Clathr_ClatBox_2 |
| ELM Description: | This variant clathrin box motif (also called the W box) is found in tandem arrangement with a "classical" clathrin box, (LIG_Clathr_ClatBox_1) in a subgroup of cargo adaptor proteins enriched in nerve terminals: the amphiphysins. It is also found in sorting nexin-9. Both motifs bind the beta propeller structure of Clathrin heavy chain with a similar affinity (Ramjaun,1998, Slepnev,2000) but at distinct sites and while the classical clathrin box assumes an extended conformation, the W box is compact and helical (Miele,2004). A synergistic effect of appropriately spaced type 1 and 2 clathrin boxes on clathrin assembly and recruitment has been shown in vitro (Drake,2001). Amphiphysin 1 is the dominant autoantigen of paraneoplastic stiff-man syndrome. |
