FunFam 106153: Pollen receptor-like kinase 1

There are 5 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.

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.
 4 A0A0B2PL53 A0A0B2QR92 A0A0B2S4J4 K7M8N2
2-alkenal reductase (NAD(P)(+)). [EC: 1.3.1.74]
A n-alkanal + NAD(P)(+) = an alk-2-enal + NAD(P)H.
  • Highly specific for 4-hydroxynon-2-enal and non-2-enal.
  • Alk-2-enals of shorter chain have lower affinities.
  • Exhibits high activities also for alk-2-enones such as but-3-en-2-one and pent-3-en-2-one.
  • Inactive with cyclohex-2-en-1-one and 12-oxophytodienoic acid.
  • Involved in the detoxification of alpha,beta-unsaturated aldehydes and ketones (cf. EC 1.3.1.102).
 3 B9RCN2 B9SZF8 B9T6G8
[Tau protein] kinase. [EC: 2.7.11.26]
ATP + [tau protein] = ADP + [tau protein] phosphate.
  • Activated by tubulin.
  • Involved in the formation of paired helical filaments, which are the main fibrous component of all fibrillary lesions in brain and are associated with Alzheimer's disease.
  • Formerly EC 2.7.1.135.
 3 B9STM4 B9T5A8 B9T6G8
Non-specific serine/threonine protein kinase. [EC: 2.7.11.1]
ATP + a protein = ADP + a phosphoprotein.
  • This is a heterogeneous group of serine/threonine protein kinases that do not have an activating compound and are either non-specific or their specificity has not been analyzed to date.
  • Formerly EC 2.7.1.37 and EC 2.7.1.70.
