Spatio-temporal expression analysis of the calcium-binding protein calumenin in the rodent brain.

ABSTRACT: Calumenin is a Ca(2+)-binding protein that belongs to the CREC superfamily. It contains six EF-hand domains that exhibit a low affinity for Ca(2+) as well as an endoplasmic reticulum retention signal. Calumenin exhibits a broad and relatively high expression in various brain regions during development as demonstrated by in situ hybridization. Signal intensity of calumenin is highest during the early development and then declines over time to reach a relatively low expression in adult animals. Immunohistochemistry indicates that at the P0 stage, calumenin expression is most abundant in migrating neurons in the zones around the lateral ventricle. In the brain of adult animals, it is expressed in various glial and neuronal cell types, including immature neurons in subgranular zone of hippocam
