Modeling Ca2+ signaling differentiation during oocyte maturation.

abstract：:In non-excitable cells, the inositol 1,4,5-trisphosphate receptor (IP3R) is an intracellular Ca2+ channel playing a major role in Ca2+ signaling. Three isoforms of IP3R have been identified and most cell types express different proportions of each isoform. The DT40 B lymphocyte cell line lacking all three IP3R isoform...
