PF00008EGF-like domain (EGF)EGF-like domainThere is no clear separation between noise and signal. Pfam:PF00053 is very similar, but has 8 instead of 6 conserved cysteines.

Pfam:PF00053 is very similar, but has 8 instead of 6 conserved cysteines. Includes some cytokine receptors. The EGF domain misses the N-terminus regions of the Ca2+ binding EGF domains (this is the main reason of discrepancy between swiss-prot domain start/end and Pfam). The family is hard to model due to many similar but different sub-types of EGF domains. Pfam certainly misses a number of EGF domains.
Domain
PF14670Coagulation Factor Xa inhibitory site (FXa_inhibition)Coagulation Factor Xa inhibitory siteThis short domain on coagulation enzyme factor Xa is found to be the target for a potent inhibitor of coagulation, TAK-442 [1]. Domain
PF00594Vitamin K-dependent carboxylation/gamma-carboxyglutamic (GLA) domain (Gla)Vitamin K-dependent carboxylation/gamma-carboxyglutamic (GLA) domainThis domain is responsible for the high-affinity binding of calcium ions. This domain contains post-translational modifications of many glutamate residues by Vitamin K-dependent carboxylation to form gamma-carboxyglutamate (Gla). Domain

In some members of the family there is an additional fourth disulphide bridge the links the N and C termini of the domain. The domain is found in diverse proteins, in some they mediate protein-protein interactions, in others they mediate protein-carbohydrate interactions.
