Summary: Thrombomodulin like fifth domain, EGF-like
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.
Thrombomodulin like fifth domain, EGF-like Provide feedback
Members of this family adopt a fold similar to other EGF domains, with a flat major and a twisted minor beta sheet. Disulphide pairing, however, is not of the usual 1-3, 2-4, 5-6 type; rather 1-2, 3-4, 5-6 pairing is found. Its extended major sheet (strands beta-2 and beta-3 and the connecting loop) projects into thrombin's active site groove. This domain is required for interaction of thrombomodulin with thrombin, and subsequent activation of protein-C .

Members of this clan all belong to the EGF superfamily. This particular superfamily is characterised as having least 6 cysteines residues. These cysteine form disulphide bonds, in the order 1-3, 2-4, 5-6, which are essential for the stability of the EGF fold. These disulphide bonds are stacked in a ladder-like arrangement. The Laminin EGF family is distinguished by having an an additional disulphide bond. The function of the domains within this family remains unclear, but they are though to largely perform a structural role. More often than not, there domains are arranged a tandem repeats in extracellular proteins.
The clan contains the following 13 members:cEGF DSL EGF EGF_2 EGF_3 EGF_alliinase EGF_CA EGF_MSP1_1 FOLN FXa_inhibition hEGF Laminin_EGF Tme5_EGF_like
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
