Inositol 1,4,5-trisphosphate receptor binding protein is a ubiquitous protein involved in the Ca2+ signalling processes in a variety of organisms [1]
Structure
The specific type of inositol 1,4,5-trisphosphate receptor (InsP3R)protein discussed here is the mouse type one InsP3R, also called InsP3R1. This polypeptide contains three major regions: the amino terminal inositol 1,4,5-trisphosphate (InsP3) binding region, the central modulatory region, and the carboxy-terminus channel region.1 The protein forms an L-shaped structure composed of two asymmetric domains perpendicular to each other.[1] The N-terminal domain is made up of 12 β-strands and 2 single-turn helices.[1] These components form a barrel. The C-terminal end is quite different, consisting of a bundle made of eight α-helices.[1] The interface of the two domains is lined with basic residues and forms the receptor site for InsP3.[1]
