CAMK2D (Calcium/calmodulin dependent protein kinase II delta)

The Function of CAMK2D

Calcium/calmodulin-dependent protein kinase involved in the regulation of Ca(2+) homeostatis and excitation-contraction coupling (ECC) in heart by targeting ion channels, transporters and accessory proteins involved in Ca(2+) influx into the myocyte, Ca(2+) release from the sarcoplasmic reticulum (SR), SR Ca(2+) uptake and Na(+) and K(+) channel transport. Targets also transcription factors and signaling molecules to regulate heart function. In its activated form, is involved in the pathogenesis of dilated cardiomyopathy and heart failure. Contributes to cardiac decompensation and heart failure by regulating SR Ca(2+) release via direct phosphorylation of RYR2 Ca(2+) channel on 'Ser-2808'. In the nucleus, phosphorylates the MEF2 repressor HDAC4, promoting its nuclear export and binding to 14-3-3 protein, and expression of MEF2 and genes involved in the hypertrophic program. Is essential for left ventricular remodeling responses to myocardial infarction. In pathological myocardial remodeling acts downstream of the beta adrenergic receptor signaling cascade to regulate key proteins involved in ECC. Regulates Ca(2+) influx to myocytes by binding and phosphorylating the L-type Ca(2+) channel subunit beta-2 CACNB2. In addition to Ca(2+) channels, can target and regulate the cardiac sarcolemmal Na(+) channel Nav1.5/SCN5A and the K+ channel Kv4.3/KCND3, which contribute to arrhythmogenesis in heart failure. Phosphorylates phospholamban (PLN/PLB), an endogenous inhibitor of SERCA2A/ATP2A2, contributing to the enhancement of SR Ca(2+) uptake that may be important in frequency-dependent acceleration of relaxation (FDAR) and maintenance of contractile function during acidosis. May participate in the modulation of skeletal muscle function in response to exercise, by regulating SR Ca(2+) transport through phosphorylation of PLN/PLB and triadin, a ryanodine receptor-coupling factor.

Technical

The following transcription factors affect gene expression:

  • CREB
  • AhR
  • Arnt
  • c-Jun
  • deltaCREB
  • SREBP-1a

Tissue specificity:

Expressed in cardiac muscle and skeletal muscle. Isoform Delta 3, isoform Delta 2, isoform Delta 8 and isoform Delta 9 are expressed in cardiac muscle. Isoform Delta 11 is expressed in skeletal muscle.

Gene Pathways:

  • Immune System
  • Melanogenesis
  • Wnt signaling pathway
  • Calcium signaling pathway
  • Cellular responses to stress
  • Tuberculosis
  • Neurotrophin signaling pathway
  • Glioma
  • Gastric acid secretion
  • Neuronal System
  • Olfactory transduction
  • Oocyte meiosis
  • GnRH signaling pathway
  • Long-term potentiation

Induction:

Activity is induced in skeletal muscle during exercise.

Enzyme Regulation:

Activated by Ca(2+)/calmodulin. Binding of calmodulin results in conformational change that relieves intrasteric autoinhibition and allows autophosphorylation of Thr-287 which turns the kinase in a constitutively active form and confers to the kinase a Ca(2+)-independent activity.
