Function

Key calcium ion sensor involved in the Ca(2+)-triggered synaptic vesicle-plasma membrane fusion. Plays a role in the sarcolemma repair mechanism of both skeletal muscle and cardiomyocytes that permits rapid resealing of membranes disrupted by mechanical stress (By similarity). {ECO:0000250}.

Subcellular Localization

Cell membrane, sarcolemma; Single-pass type II membrane protein. Cytoplasmic vesicle membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Cell membrane. Note=Colocalizes, during muscle differentiation, with BIN1 in the T-tubule system of myotubules and at the site of contact between two myotubes or a myoblast and a myotube. Wounding of myotubes led to its focal enrichment to the site of injury and to its relocalization in a Ca(2+)-dependent manner toward the plasma membrane. Colocalizes with AHNAK, AHNAK2 and PARVB at the sarcolemma of skeletal muscle. Detected on the apical plasma membrane of the syncytiotrophoblast. Reaches the plasmma membrane through a caveolin-independent mechanism. Retained by caveolin at the plasmma membrane (By similarity). Colocalizes, during muscle differentiation, with CACNA1S in the T-tubule system of myotubules (By similarity). Accumulates and colocalizes with fusion vesicles at the sarcolemma disruption sites (By similarity). {ECO:0000250}.

Disease Associations

Limb-girdle muscular dystrophy 2B (LGMD2B) [MIM:253601]: An autosomal recessive degenerative myopathy characterized by weakness and atrophy starting in the proximal pelvifemoral muscles, with onset in the late teens or later, massive elevation of serum creatine kinase levels and slow progression. Scapular muscle involvement is minor and not present at onset. Upper limb girdle involvement follows some years after the onset in lower limbs. {ECO:0000269PubMed:10196377, ECO:0000269PubMed:11134403, ECO:0000269PubMed:14678801, ECO:0000269PubMed:15469449, ECO:0000269PubMed:16010686, ECO:0000269PubMed:16100712, ECO:0000269PubMed:16705711, ECO:0000269PubMed:16996541, ECO:0000269PubMed:17287450, ECO:0000269PubMed:18306167, ECO:0000269PubMed:18853459, ECO:0000269PubMed:9731526}. Note=The disease is caused by mutations affecting the gene represented in this entry.Miyoshi muscular dystrophy 1 (MMD1) [MIM:254130]: A late- onset muscular dystrophy involving the distal lower limb musculature. It is characterized by weakness that initially affects the gastrocnemius muscle during early adulthood. {ECO:0000269PubMed:10196377, ECO:0000269PubMed:11134403, ECO:0000269PubMed:11468312, ECO:0000269PubMed:12796534, ECO:0000269PubMed:15116377, ECO:0000269PubMed:15469449, ECO:0000269PubMed:15477515, ECO:0000269PubMed:15515206, ECO:0000269PubMed:16010686, ECO:0000269PubMed:16100712, ECO:0000269PubMed:17287450, ECO:0000269PubMed:18306167, ECO:0000269PubMed:18853459, ECO:0000269PubMed:9731526, ECO:0000269Ref.25}. Note=The disease is caused by mutations affecting the gene represented in this entry.Distal myopathy with anterior tibial onset (DMAT) [MIM:606768]: Onset of the disorder is between 14 and 28 years of age and the anterior tibial muscles are the first muscle group to be involved. Inheritance is autosomal recessive. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Expressed in skeletal muscle, myoblast, myotube and in the syncytiotrophoblast (STB) of the placenta (at protein level). Ubiquitous. Highly expressed in skeletal muscle. Also found in heart, brain, spleen, intestine, placenta and at lower levels in liver, lung, kidney and pancreas. {ECO:0000269PubMed:10196375, ECO:0000269PubMed:11532985, ECO:0000269PubMed:11959863, ECO:0000269PubMed:15318348, ECO:0000269PubMed:16896923, ECO:0000269PubMed:17185750, ECO:0000269PubMed:17363620, ECO:0000269PubMed:17554076, ECO:0000269PubMed:24239457}.
