Biochemical Activity (Phosphorylation)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Caldesmon phosphorylation in intact human platelets by cAMP-dependent protein kinase and protein kinase C.

Hettasch JM, Sellers JR

Caldesmon is a calmodulin- and actin-binding protein present in both smooth and non-muscle tissue. The present study demonstrates that platelet caldesmon is a substrate for cAMP-dependent protein kinase (protein kinase A). Purified platelet caldesmon has an apparent molecular mass of 82 kDa on sodium dodecyl sulfate-polyacrylamide gels and can be phosphorylated in vitro by the catalytic subunit of protein kinase ...

Throughput

  • Low Throughput

Additional Notes

  • Active PKA phosphorylated caldesmon in in vitro and probably in intact platelets
  • PKA was activated by pretreatment of platelets by prostacyclin (PGI2) treatment.
