Summary: Predicted to enable identical protein binding activity. Involved in positive regulation of protein localization to plasma membrane and positive regulation of voltage-gated calcium channel activity. Acts upstream of or within skeletal muscle fiber development. Located in cytoplasmic side of plasma membrane and cytosol. Part of voltage-gated calcium channel complex. Is expressed in limb musculature; somite; and tongue. Human ortholog(s) of this gene implicated in Native American myopathy. Orthologous to human STAC3 (SH3 and cysteine rich domain 3).

Testicular STAC3 regulates Leydig cell steroidogenesis through potentiating mitochondrial membrane potential and StAR processing.
Title: Testicular STAC3 regulates Leydig cell steroidogenesis through potentiating mitochondrial membrane potential and StAR processing.
RyR1 Ca2+ release by CaV1.1 depends on Stac3 being bound to critical domain residues in the II-III loop.
Title: Stac proteins associate with the critical domain for excitation-contraction coupling in the II-III loop of Ca(V)1.1.
we provide evidence that endogenous STAC3 incorporates into triads in the absence of the DHPR in myotubes and muscle fibers of dysgenic mice. This finding demonstrates that STAC3 interacts with additional triad proteins and is consistent with its proposed role in directly or indirectly linking the DHPR with the RyR1
Title: STAC3 incorporation into skeletal muscle triads occurs independent of the dihydropyridine receptor.
Thus, the C1 domain of STAC3 is responsible for its stable incorporation into the voltage-sensor (CaV1.1) of excitation-contraction-coupling complex, whereas the SH3 domain containing the Native American myopathy mutation site may be involved in low-affinity functional interactions in excitation-contraction-coupling.
Title: STAC3 stably interacts through its C1 domain with Ca(V)1.1 in skeletal muscle triads.
These data together confirm a critical role of STAC3 in excitation-contraction coupling but also suggest that STAC3 may have additional functions in skeletal muscle, at least in the hindlimb muscle.
Title: Defective excitation-contraction coupling is partially responsible for impaired contractility in hindlimb muscles of Stac3 knockout mice.
Stac3 is directly involved in conformational coupling between CaV1.1 and RyR1.
Title: Stac3 has a direct role in skeletal muscle-type excitation-contraction coupling that is disrupted by a myopathy-causing mutation.
STAC3 is important to myofiber hypertrophy, myofiber-type composition, contraction, and excitation-induced calcium release from the sarcoplasmic reticulum in the postnatal skeletal muscle.
Title: The SH3 and cysteine-rich domain 3 (Stac3) gene is important to growth, fiber composition, and calcium release from the sarcoplasmic reticulum in postnatal skeletal muscle.
Stac3 may play a role in preventing precocious myoblast differentiation during skeletal muscle development

Stac3 gene plays a critical role in skeletal muscle development and function in mice.

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.
