WB Use a concentration of 1 µg/ml. Detects a band of approximately 25 kDa (predicted molecular weight: 25 kDa).


  • FunctionModulates calcium-dependent activity of inositol 1,4,5-triphosphate receptors (ITPRs). Inhibits agonist-induced intracellular calcium signaling. Enhances inactivation and does not support calcium-dependent facilitation of voltage-dependent P/Q-type calcium channels. Causes calcium-dependent facilitation and inhibits inactivation of L-type calcium channels by binding to the same sites as calmodulin in the C-terminal domain of CACNA1C, but resulting in an opposit effects on channel function. Suppresses the calcium-dependent inactivation of CACNA1D (By similarity). Inhibits TRPC5 channels. Prevents NMDA receptor-induced cellular degeneration.
  • Tissue specificityRetina and brain. Somatodendritic compartment of neurons. Calbrain was found exclusively in brain where it is abundant in the hippocampus, habenular area in the epithalamus and in the cerebellum.
  • Sequence similaritiesContains 4 EF-hand domains.
  • DomainEF-1 binds magnesium constitutively under physiological conditions, EF-3 and EF-4 bind calcium cooperatively and EF-2 binds neither calcium nor magnesium.
  • Post-translational
    Phosphorylated. The phosphorylation regulates the activity.
  • Cellular localizationCytoplasm > cell cortex. Cell membrane. S-CaBP1 is localized at or near the plasma membrane; Cytoplasm > cytoskeleton. Cytoplasm > perinuclear region. Cell membrane. Golgi apparatus. Cell junction > synapse > postsynaptic cell membrane > postsynaptic density. L-CaBP1 is associated most likely with the cytoskeletal structures, whereas S-CaBP1 is localized at or near the plasma membrane and Cytoplasm > cytoskeleton. L-CaBP1 is associated most likely with the cytoskeletal structures.
