|---|---|
| Primary Accession | Q9NZU7 |
| Other Accession | Q9NZU7 |
| Host | Rabbit |
| Clonality | Polyclonal |
| Calculated MW | 39838 Da |
| Physical State | Liquid |
| Immunogen | KLH conjugated synthetic peptide derived from human CABP1 |
| Epitope Specificity | 311-355/370 |
| Isotype | IgG |
| Purity | affinity purified by Protein A |
| Buffer | 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. |
| SIMILARITY | Contains 4 EF-hand domains. |
| SUBUNIT | Homodimer; when bound to calcium or magnesium. Interacts (via C-terminus) with ITPR1, ITPR2 and ITPR3. This binding is calcium dependent and the interaction correlates with calcium concentration. An additional calcium-independent interaction with the N-terminus of ITPR1 results in a decreased InsP(3) binding to the receptor. Interacts with CACNA1A (via C-terminal CDB motif) in the pre- and postsynaptic membranes. Interacts with CACNA1C (via C-terminal C and IQ motifs). The binding to the C motif is calcium independent whereas the binding to IQ requires the presence of calcium and is mutually exclusive with calmodulin binding. Interacts with CACNA1D (By similarity). Interacts with TRPC5 (via C-terminus). Interacts (via EF-hands 1 and 2) at microtubules with MAP1LC3B. Interacts with MYO1C and NELF |
| Post-translational modifications | Phosphorylated. The phosphorylation regulates the activity. |

| Background Descriptions | Calcium plays an essential role in many biological processes. The calcium binding protein (CaBP) family shares much similarity to calmodulin. It has been shown that CaBP proteins can substitute functionally for, and probably augment the function of, calmodulin. Calcium binding proteins are a crucial part of calcium mediated cellular signal transduction in the central nervous system. There are several members of the family with varying expression patterns. CaBP1 and CaBP2 can be expressed as multiple, alternatively spliced variants in brain and retina. CaBP3, CaBP4 and CaBP 5 are restricted to retinal rod and cone cells. CaBP7 shares 70% homology with CaBP8 and 50% homology with CaM I. |

| Function | Modulates calcium-dependent activity of inositol 1,4,5- triphosphate receptors (ITPRs) (PubMed:14570872). Inhibits agonist- induced intracellular calcium signaling (PubMed:15980432). Enhances inactivation and does not support calcium-dependent facilitation of voltage-dependent P/Q-type calcium channels (PubMed:11865310). 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 has an opposite effect on channel function (PubMed:15140941). Suppresses the calcium-dependent inactivation of CACNA1D (By similarity). Inhibits TRPC5 channels (PubMed:15895247). Prevents NMDA receptor-induced cellular degeneration. Required for the normal transfer of light signals through the retina (By similarity). |
| Cellular Location | Cytoplasm, cytoskeleton. Cytoplasm, perinuclear region. Cell membrane; Lipid-anchor; Cytoplasmic side. Golgi apparatus Postsynaptic density. Note=L-CaBP1 is associated most likely with the cytoskeletal structures, whereas S-CaBP1 is localized at or near the plasma membrane. [Isoform S-CaBP1]: Cytoplasm, cell cortex. Cell membrane; Lipid-anchor Note=S-CaBP1 is localized at or near the plasma membrane |
| Tissue Location | Retina 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 |
