CC -!- FUNCTION: Adapter protein that binds to and probably organizes the
CC subcellular localization of a variety of membrane proteins. May link
CC various receptors to the actin cytoskeleton and the extracellular
CC matrix via the dystrophin glycoprotein complex. Plays an important role
CC in synapse formation and in the organization of UTRN and acetylcholine
CC receptors at the neuromuscular synapse. Binds to phosphatidylinositol
CC 4,5-bisphosphate (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Monomer and homodimer. Interacts with the other members of the
CC syntrophin family SNTB1 and SNTB2; SGCG and SGCA of the dystrophin
CC glycoprotein complex; NOS1; GRB2; the sodium channel proteins SCN4A and
CC SCN5A; F-actin and calmodulin (By similarity). Interacts with
CC dystrophin protein DMD and related proteins DTNA and UTRN and with
CC MAPK12, TGFA and GA. Interacts with MYOC; regulates muscle hypertrophy
CC (By similarity). Interacts with DTNB (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:Q61234}.
CC -!- INTERACTION:
CC Q13424; O95477: ABCA1; NbExp=2; IntAct=EBI-717191, EBI-784112;
CC Q13424; P25100: ADRA1D; NbExp=11; IntAct=EBI-717191, EBI-489993;
CC Q13424; Q63538: Mapk12; Xeno; NbExp=5; IntAct=EBI-717191, EBI-783937;
CC -!- SUBCELLULAR LOCATION: Cell membrane, sarcolemma {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC {ECO:0000250}. Cell junction {ECO:0000250}. Cytoplasm, cytoskeleton
CC {ECO:0000250}. Note=In skeletal muscle, it localizes at the cytoplasmic
CC side of the sarcolemmal membrane and at neuromuscular junctions.
CC {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q13424-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q13424-2; Sequence=VSP_056827;
CC -!- TISSUE SPECIFICITY: High expression in skeletal muscle and heart. Low
CC expression in brain, pancreas, liver, kidney and lung. Not detected in
CC placenta.
CC -!- DOMAIN: The PH 1 domain mediates the oligomerization in a calcium
CC dependent manner, and the association with the phosphatidylinositol
CC 4,5-bisphosphate. {ECO:0000250}.
CC -!- DOMAIN: The PDZ domain binds to the last three or four amino acids of
CC ion channels and receptor proteins. The association with dystrophin or
CC related proteins probably leaves the PDZ domain available to recruit
CC proteins to the membrane (By similarity). {ECO:0000250}.
CC -!- DOMAIN: The SU domain binds calmodulin in a calcium-dependent manner.
CC {ECO:0000250}.
CC -!- PTM: Phosphorylated by CaM-kinase II. Phosphorylation may inhibit the
CC interaction with DMD (By similarity). {ECO:0000250}.
CC -!- DISEASE: Long QT syndrome 12 (LQT12) [MIM:612955]: A heart disorder
CC characterized by a prolonged QT interval on the ECG and polymorphic
CC ventricular arrhythmias. They cause syncope and sudden death in
CC response to exercise or emotional stress, and can present with a
CC sentinel event of sudden cardiac death in infancy.
CC {ECO:0000269|PubMed:18591664, ECO:0000269|PubMed:19684871}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- SIMILARITY: Belongs to the syntrophin family. {ECO:0000305}.
