Predicted to enable protein-macromolecule adaptor activity and transmembrane transporter binding activity. Involved in several processes, including cytoplasmic microtubule organization; endoplasmic reticulum membrane organization; and regulation of release of sequestered calcium ion into cytosol. Located in junctional sarcoplasmic reticulum membrane and plasma membrane. Part of calcium channel complex and junctional membrane complex. Human ortholog(s) of this gene implicated in catecholaminergic polymorphic ventricular tachycardia and catecholaminergic polymorphic ventricular tachycardia 5. Orthologous to human TRDN (triadin).
