Snta1 - syntrophin, alpha 1

Enables PDZ domain binding activity. Predicted to be involved in several processes, including negative regulation of peptidyl-cysteine S-nitrosylation; regulation of ion transmembrane transport; and ventricular cardiac muscle cell action potential. Predicted to act upstream of or within neuromuscular junction development and regulation of vasoconstriction by circulating norepinephrine. Located in neuromuscular junction and sarcolemma. Biomarker of status epilepticus. Human ortholog(s) of this gene implicated in long QT syndrome; long QT syndrome 12; and sudden infant death syndrome. Orthologous to human SNTA1 (syntrophin alpha 1).
