Summary: Predicted to enable protein-macromolecule adaptor activity. Involved in several processes, including cytoplasmic microtubule organization; myotube differentiation; 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).

Acute aerobic exercise regulation of myocardial calcium homeostasis involves CASQ1, CASQ2, and TRDN.
Title: Acute aerobic exercise regulation of myocardial calcium homeostasis involves CASQ1, CASQ2, and TRDN.
findings show that Trisk 32 not only co-localizes with, but directly contributes to, the regulation of Ca(2+) release via IP(3) receptors
Title: Trisk 32 regulates IP(3) receptors in rat skeletal myoblasts.
Trisk 95 negatively regulates ryanodine receptor function by suppressing localized calcium release events and global calcium signals in cultured muscle cells.
Title: Altered expression of triadin 95 causes parallel changes in localized Ca2+ release events and global Ca2+ signals in skeletal muscle cells in culture.
proteasome inhibition led to an accumulation of two new modified forms of triadin-1 that were seen with triadin-1 only when it is not glycosylated on Asn(75).
Title: Inefficient glycosylation leads to high steady-state levels of actively degrading cardiac triadin-1.
Calsequestrin (CASQ2) stabilizes sarcoplasmic reticulum Ca2+ release by inhibiting the RyR2 channel through interaction with triadin (Trd).
Title: Protein protein interactions between triadin and calsequestrin are involved in modulation of sarcoplasmic reticulum calcium release in cardiac myocytes.
the level of Trisk 95 and not Trisk 51 is important on regulating the calcium release complex, and an excess of this protein can lead to an inhibition of the physiological function of the complex
Title: Triadin (Trisk 95) overexpression blocks excitation-contraction coupling in rat skeletal myotubes.
In conclusion, the RyR-interacting molecule T95, recently shown to inhibit the excitation-contraction coupling, has also the ability to interfere with the skeletal muscle Ca2+ signalling by depressing thapsigargin-dependent Ca2+ release and influx.
Title: Retrograde regulation of store-operated calcium channels by the ryanodine receptor-associated protein triadin 95 in rat skeletal myotubes.
The expression of Trdn was studied during muscle development in a novel three-dimensional muscle-neuronal coculture system.
Title: Expression of Trisk 51, agrin and nicotinic-acetycholine receptor epsilon-subunit during muscle development in a novel three-dimensional muscle-neuronal co-culture system.
TRD enhances cardiac excitation-contraction coupling by directly stimulating the RyR2. Interaction of TRD with RyR2 may involve amino acids 200 to 224 in C-terminal domain of TRD.
Title: Triadin overexpression stimulates excitation-contraction coupling and increases predisposition to cellular arrhythmia in cardiac myocytes.
could be involved in the set up and maintenance of a precise sarcoplasmic reticulum structure.
Title: Triadins are not triad-specific proteins: two new skeletal muscle triadins possibly involved in the architecture of sarcoplasmic reticulum.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
