FunFam 24962: Lectin receptor kinase 1

There are 11 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

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.

Non-specific protein-tyrosine kinase. [EC: 2.7.10.2]
ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
  • Unlike EC 2.7.10.1, this protein-tyrosine kinase does not have a transmembrane domain.
  • In the human genome, 32 non-specific protein-tyrosine kinases have been identified and these can be divided into 10 families.

Cyclin-dependent kinase. [EC: 2.7.11.22]
ATP + a protein = ADP + a phosphoprotein.
  • Activation of cyclin-dependent kinases requires association of the enzyme with a regulatory subunit referred to as a cyclin.
  • It is the sequential activation and inactivation of cyclin-dependent kinases, through the periodic synthesis and destruction of cyclins, that provides the primary means of cell-cycle regulation.
  • Formerly EC 2.7.1.37.

Receptor protein serine/threonine kinase. [EC: 2.7.11.30]
ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.
  • The transforming growth factor beta (TGF-beta) family of cytokines regulates cell proliferation, differentiation, recognition and death.
  • Signaling occurs by the binding of ligand to the type II receptor, which is the constitutively active kinase.
  • Bound TGF-beta is then recognized by receptor I, which is phosphorylated and can propagate the signal to downstream substrates.
  • Formerly EC 2.7.1.37.

Mitogen-activated protein kinase kinase kinase. [EC: 2.7.11.25]
ATP + a protein = ADP + a phosphoprotein.
  • This enzyme phosphorylates and activates its downstream protein kinase, EC 2.7.12.2, but requires MAPKKKK for activation.
  • Some members of this family can be activated by p21-activated kinases (PAK/STE20) or Ras.
  • While c-Raf and c-Mos activate the classical MAPK/ERK pathway, MEKK1 and MEKK2 preferentially activate the c-Jun N-terminal protein kinase(JNK)/stress-activated protein kinase (SAPK) pathway.
  • Mitogen-activated protein kinase (MAPK) signal transduction pathways are among the most widespread mechanisms of cellular regulation.
  • Mammalian MAPK pathways can be recruited by a wide variety of stimuli including hormones (e.g. insulin and growth hormone), mitogens (e.g. epidermal growth factor and platelet-derived growth factor), vasoactive peptides (e.g. angiotensin-II and endothelin), inflammatory cytokines of the tumor necrosis factor (TNF) family and environmental stresses such as osmotic shock, ionizing radiation and ischemeic injury.
  • Formerly EC 2.7.1.37.

Mannan-binding lectin-associated serine protease-2. [EC: 3.4.21.104]
Selective cleavage after Arg-223 in complement component C2 (-Ser- Leu-Gly-Arg-|-Lys-Ile-Gln-Ile) and after Arg-76 in complement component C4 (-Gly-Leu-Gln-Arg-|-Ala-Leu-Glu-Ile).
  • Mannan-binding lectin (MBL) recognizes patterns of neutral carbohydrates, such as mannose and N-acetylglucosamine, on a wide range of microbial surfaces and is able to initiate activation of the lectin pathway of complement.
  • Displays C1s-like esterolytic activity (cf. EC 3.4.21.42).
  • It also cleaves C4 and C2 with efficiencies that are relatively higher than those of EC 3.4.21.42.
  • Belongs to peptidase family S1A.

Type II site-specific deoxyribonuclease. [EC: 3.1.21.4]
Endonucleolytic cleavage of DNA to give specific double-stranded fragments with terminal 5'-phosphates.
  • Large group of enzymes which recognize specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition site.
  • See the REBASE database for a complete list of these enzymes: http://rebase.neb.com/rebase/

Polo kinase. [EC: 2.7.11.21]
ATP + a protein = ADP + a phosphoprotein.
  • The enzyme associates with the spindle pole during mitosis and is thought to play an important role in the dynamic function of the mitotic spindle during chromosome segregation.
  • The human form of the enzyme, Plk1, does not phosphorylate histone H1, enolase and phosvitin but it can phosphorylate myelin basic protein and microtubule-associated protein MAP-2, although to a lesser extent than casein.
  • Formerly EC 2.7.1.37.
 2 B9RX81 B9RX81
Mitogen-activated protein kinase kinase. [EC: 2.7.12.2]
ATP + a protein = ADP + a phosphoprotein.
  • A dual-specific protein kinase and requires mitogen-activated protein kinase kinase kinase (MAPKKK) for activation.
  • It is required for activation of EC 2.7.11.24.
  • Phosphorylation of MEK1 by Raf involves phosphorylation of two serine residues.
  • Mitogen-activated protein kinase (MAPK) signal transduction pathways are among the most widespread mechanisms of cellular regulation.
  • Mammalian MAPK pathways can be recruited by a wide variety of stimuli including hormones (e.g. insulin and growth hormone), mitogens (e.g. epidermal growth factor and platelet-derived growth factor), vasoactive peptides (e.g. angiotensin-II and endothelin), inflammatory cytokines of the tumor necrosis factor (TNF) family and environmental stresses such as osmotic shock, ionizing radiation and ischemeic injury.

  • Requires calmodulin.
  • A wide range of proteins can act as acceptor, including vimentin, synapsin, glycogen synthase, myosin light-chains and the microtubule- associated tau protein.
