Summary: Predicted to enable calcium ion binding activity. Predicted to be involved in regulation of long-term synaptic potentiation and regulation of presynaptic cytosolic calcium ion concentration. Predicted to be active in several cellular components, including cytosol; dendrite; and terminal bouton. Is expressed in several structures, including head; nervous system; neural rod; neural tube; and sensory epithelial cell. Orthologous to human CALB2 (calbindin 2).

Perturbed development of calb2b expressing dI6 interneurons and motor neurons underlies locomotor defects observed in calretinin knock-down zebrafish larvae.
Title: Perturbed development of calb2b expressing dI6 interneurons and motor neurons underlies locomotor defects observed in calretinin knock-down zebrafish larvae.
Calb2a and Calb2b are highly conserved across vertebrate species and originated from the same ancestral gene long back in the evolution. Homology modeling and docking with the similar structure and Ca(2+) binding sites for both proteins provide the evidence that both the proteins may have similar function and one can compensate for the loss of other.

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.
