thumb|325x325px|Junctophilin-3Junctophilin-3 (JPH3) is a protein residing in humans that is encoded by the JPH3 gene. The gene is approximately 97 kilobases long and is located at chromosomal position 16q24.2. Junctophilin proteins are associated with the formation of junctional membrane complexes, which link the plasma membrane with the endoplasmic reticulum in excitable cells. JPH3 is localized to the brain and is associated with motor coordination and memory neurons.

The protein contains 748 residues and is composed of a C-terminal hydrophobic segment that spans the endoplasmic/sarcoplasmic reticulum membrane and a cytoplasmic domain that displays specific affinity for the plasma membrane, as well as several membrane occupation and recognition nexus repeats involved in plasma membrane binding through interactions with phospholipids.
