Chains Pfam Accession Pfam Identifier Pfam Description Type Source
T PF01108 Tissue_fac Tissue factor Family
L PF14670 FXa_inhibition Coagulation Factor Xa inhibitory site Domain This short domain on coagulation enzyme factor Xa is found to be the target for a potent inhibitor of coagulation, TAK-442 [1]. PFAM PF14670
I PF00014 Kunitz_BPTI Kunitz/Bovine pancreatic trypsin inhibitor domain Domain Indicative of a protease inhibitor, usually a serine protease inhibitor. Structure is a disulfide rich alpha+beta fold. BPTI (bovine pancreatic trypsin inhibitor) is an extensively studied model structure. Certain family members are similar to the tick anticoagulant peptide (TAP, Swiss:P17726). This is a highly selective inhibitor of factor Xa in the blood coagulation pathways [1]. TAP molecules are highly dipolar [2], and are arranged to form a twisted two- stranded antiparallel beta-sheet followed by an alpha helix [1]. PFAM PF00014
L PF00594 Gla Vitamin K-dependent carboxylation/gamma-carboxyglutamic (GLA) domain Domain This 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). PFAM PF00594
T PF09294 Interfer-bind Interferon-alpha/beta receptor, fibronectin type III Domain Members of this family adopt a secondary structure consisting of seven beta-strands arranged in an immunoglobulin-like beta-sandwich, in a Greek-key topology. They are required for binding to interferon-alpha [1]. PFAM PF09294
H PF00089 Trypsin Trypsin Domain PFAM PF00089
L PF00008 EGF EGF-like domain Domain There is no clear separation between noise and signal. 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. PFAM PF00008
