FunFam 19398: MAGUK p55 subfamily member 2

There are 3 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
Guanylate kinase. [EC:]
  • dGMP can also act as acceptor.
  • dATP can act as donor.

Non-specific serine/threonine protein kinase. [EC:]
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 and EC

Calcium/calmodulin-dependent protein kinase. [EC:]
ATP + a protein = ADP + a phosphoprotein.
  • 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.
  • Not identical with EC EC or EC
  • Formerly EC and EC
