Inositol 1,4,5-trisphosphate receptor, type 1 (ITPR1) is highly expressed in the rat brain and is also seen in the heart. It possesses an inositol-triphosphate binding domain, a channel-forming region and a regulatory region. ITPR1 is composed of 2749 amino acids. The gene ID for the protein is 25262.

Inositol 1,4,5-trisphosphate receptor type 1 (IP(3)R1) is already known to be highly expressed in the brain, and is found in many other tissues, including the atrium of the heart. Although the complete primary structure of IP(3)R1 in the rat brain

Binding of IP3 (inositol 1,4,5-trisphosphate) to the IP3-binding core (residues 224-604) of IP3Rs (IP3 receptors) initiates opening of these ubiquitous intracellular Ca2+ channels. The mechanisms are unresolved, but require conformational changes to pass through the suppressor domain (residues 1-223). A
Calcium signalling from the type I inositol 1,4,5-trisphosphate receptor is required at early phase of liver regeneration.

Previous studies have shown that cytosolic Ca(2+) ([Ca(2+)]c) overload was involved in Pb-induced apoptosis in primary cultures of rat proximal tubular (rPT) cells, but the source of elevated Ca(2+) and the effect of potential subcellular Ca(2+) redistribution on apoptosis are
