FunFam 33068: Low-density lipoprotein receptor 2

There are 7 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Receptor protein-tyrosine kinase. [EC: 2.7.10.1]
ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
  • The receptor protein-tyrosine kinases, which can be defined as having a transmembrane domain, are a large and diverse multigene family found only in metazoans.
  • In the human genome, 58 receptor-type protein-tyrosine kinases have been identified and these are distributed into 20 subfamilies.
  • Formerly EC 2.7.1.112.

Complement factor I. [EC: 3.4.21.45]
Inactivates complement subcomponents C3b, iC3b and C4b by proteolytic cleavage.
  • Cleavage of complement subcomponent C3b requires its binding to cofactor H or complement receptor CR1; cleavage of iC3b requires complement receptor CR1; cleavage of C4b requires C4b-binding protein.
  • Belongs to peptidase family S1.
 9 B7PJ49 B7PJ49 B7PJ49 B7PJ49 B7PJ49 B7QBX8 B7QKE3 B7QKE3 B7QMR1
Procollagen C-endopeptidase. [EC: 3.4.24.19]
Cleavage of the C-terminal propeptide at Ala-|-Asp in type I and II procollagens and at Arg-|-Asp in type III.
  • The activity is increased by calcium and by an enhancer glycoprotein.
 5 B7PJ49 B7PJ49 B7PJ49 B7PJ49 B7PJ49
Coagulation factor Xa. [EC: 3.4.21.6]
Selective cleavage of Arg-|-Thr and then Arg-|-Ile bonds in prothrombin to form thrombin.
  • A blood coagulation factor formed from the proenzyme factor X by limited proteolysis.
  • Factor X is a glycoprotein composed of a heavy chain and a light chain, which are generated from a precursor protein by the excision of the tripeptide RKR and held together by one or more disulfide bonds.
  • The activated factor Xa converts prothrombin to thrombin in the presence of factor Va, Ca(2+) and phospholipids.
  • Scutelarin (EC 3.4.21.60) has similar specificity, but does not require factor Va.
  • Belongs to peptidase family S1.
 2 B7QKE3 B7QKE3
NAD(+) ADP-ribosyltransferase. [EC: 2.4.2.30]
NAD(+) + (ADP-D-ribosyl)(n)-acceptor = nicotinamide + (ADP-D- ribosyl)(n+1)-acceptor.
  • The ADP-D-ribosyl group of NAD(+) is transferred to an acceptor carboxy group on a histone or the enzyme itself, and further ADP- ribosyl groups are transferred to the 2'-position of the terminal adenosine moiety, building up a polymer with an average chain length of 20-30 units.
 2 K1QFX2 K1QFX2
Enteropeptidase. [EC: 3.4.21.9]
Activation of trypsinogen by selective cleavage of 6-Lys-|-Ile-7 bond.
  • Activates trypsinogen.
  • Not inhibited by protein inhibitors of trypsin.
  • Belongs to peptidase family S1.
  • Formerly EC 3.4.4.8.
 1 B7QBX8
Protein C (activated). [EC: 3.4.21.69]
Degradation of blood coagulation factors Va and VIIIa.
  • One of the gamma-carboxyglutamic acid-containing coagulation factors.
  • Formed from protein C, the proenzyme that circulates in plasma, by the action of a complex of thrombin with thrombomodulin, or by serine endopeptidases present in several snake venoms.
  • Belongs to peptidase family S1.
