Data suggest that during the transition from the apo to the holo state, guided by the stepwise filling of Ca2+, caldendrin passes through distinct states and acquires a stable conformational state when only binding site EF3 (one of four EF-hand motifs) is occupied by Ca2+.
Title: Intermotif Communication Induces Hierarchical Ca(2+) Filling of Caldendrin.
Caldendrin exhibits very little change in surface hydrophobicity and secondary as well as tertiary structure upon Ca2+-binding to Mg2+-saturated protein.

that InsP3 attenuates cross-linking, whereas CaBP1 promotes it. We conclude that CaBP1 inhibits InsP3R activity by restricting the intersubunit movements that initiate gating.
Title: CaBP1, a neuronal Ca2+ sensor protein, inhibits inositol trisphosphate receptors by clamping intersubunit interactions.
these results indicate the importance of CaBP1 in signal cross talk at presynaptic group III mGluRs, which includes many molecules such as cAMP, Ca(2+), PKC, G protein, and Munc18-1.
Title: Ca2+-dependent binding of calcium-binding protein 1 to presynaptic group III metabotropic glutamate receptors and blockage by phosphorylation of the receptors.
CIB1 and CaBP1 bind to the myo1c IQ motifs in the regulatory domain where they compete with calmodulin for binding; it is proposed that these proteins may play a role in specifying subcellular localization of myo1c

The calcium sensor protein caldendrin is abundantly expressed in neurons and is thought to play an important role in different aspects of synapto-dendritic Ca2+ signaling.
Title: Neuronal Ca2+ signaling via caldendrin and calneurons.
Caldendrin is a neuronal calcium-binding protein. Two additional splice variants derive from the caldendrin gene, which have unrelated N-termini were identified in neurohypophyseal axons and on secretory granules of endocrine cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
