Jph3 Gene Summary [Mouse]
Involved in several processes, including exploration behavior; regulation of neuronal synaptic plasticity; and regulation of ryanodine-sensitive calcium-release channel activity. Acts upstream of or within learning; locomotion; and neuromuscular process controlling balance. Located in endoplasmic reticulum membrane and plasma membrane. Part of junctional membrane complex. Is expressed in brain; ganglia; retina; spinal cord; and testis. Human ortholog(s) of this gene implicated in Huntington's disease-like 2. Orthologous to human JPH3 (junctophilin 3).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Jph3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
