FunFam 721: Cyclin-dependent kinase 18

There are 4 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
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.

[RNA-polymerase]-subunit kinase. [EC: 2.7.11.23]
ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate.
  • Appears to be distinct from other protein phosphokinases.
  • Brings about multiple phosphorylation of the unique C-terminal repeat domain of the largest subunit of eukaryotic EC 2.7.7.6.
  • Does not phosphorylate casein, phosvitin or histone.
  • Formerly EC 2.7.1.141.

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.

Pyruvate dehydrogenase (acetyl-transferring). [EC: 1.2.4.1]
Pyruvate + [dihydrolipoyllysine-residue acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue acetyltransferase] S-acetyldihydrolipoyllysine + CO(2).
  • It is a component (in multiple copies) of the multienzyme pyruvate dehydrogenase complex in which it is bound to a core of molecules of EC 2.3.1.12, which also binds multiple copies of EC 1.8.1.4.
  • It does not act on free lipoamide or lipoyllysine, but only on the lipoyllysine residue in EC 2.3.1.12.
