Descrição

Descrição geral

Calcium-binding protein 1 (UniProt Q9NZU7; also known as CaBP1, Calbrain, Caldendrin) is encoded by the CABP1 gene (Gene ID 9478) in human. Caldendrin is the founding member of the nCaBP family of neuronal Ca2+-inding proteins, members of which also include CaBP2 through CaBP8. nCaBPs and neuronal calcium sensor (NCS) family members are EF-hand-type calmodulin- (CaM-) like Ca2+-sensor proteins that play important roles in neuronal Ca2+-signaling. In addition to Caldendrin, the CABP1 gene produces three other alternative splicing isoforms, L-CaBP1/Caldendrin-S2, S-CaBP1/Caldendrin-S1, and Calbrain, with varying truncated N-terminal sequence. Caldendrin, L- and S-CaBP1 share four common EF-hands, while the Calbrain isoform contains only the third and fourth EF-hands and lacks the first two. EF-hand 1 constitutively binds Mg2+ and EF-hands 3 and 4 mediate high affinity Ca2+ binding, whereas EF-hand 2 does not bind either Mg2+ or Ca2+. In addition, Caldendrin lacks the N-myristoylation sequence present in L- and S-CaBP1 and many NCS proteins. The unique Caldendrin N-terminal sequence not found in the other spliced isoforms is bipartite in nature, composed of a highly basic proline-rich N-terminal and an acidic C-terminal part. Caldendrin and S-CaBP1 are reported to interact with the L-type voltage-gated calcium channel (VGCC) Cav1.2 via different molecular determinants, and dispaly different effects on Cav1.2 channel activity.

Especificidade

Clone 11E7.1 recognizes an internal epitope in spliced isoform Caldendrin (UniProt Q9NZU7-4). The exact location of the epitope has not been mapped. Although not confirmed by direct testing, this monoclonal antibody most likely also reacts with spliced isoform L-CaBP1 (Caldendrin-S2; UniProt Q9NZU7-1), while cross-reactivity toward isoform S-CaBP1 (Caldendrin-S1; UniProt Q9NZU7-2) and isoform Calbrain (UniProt Q9NZU7-3) is unlikely.

Imunogênio

GST-tagged recombinant human CaBP1 internal fragment.

Aplicação

Immunohistochemistry Analysis: An 1:250 dilution from a representative lot detected CaBP1 in human cerebellum and human retina tissue.
