Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables several functions, including calmodulin binding activity; protein domain specific binding activity; and protein phosphatase 1 binding activity. Involved in negative regulation of DNA-templated transcription and positive regulation of vasoconstriction. Acts upstream of or within several processes, including muscle organ morphogenesis; response to activity; and vasoconstriction. Located in I band; M band; and nucleus. Is expressed in several structures, including aorta; diaphragm; genitourinary system; intestine; and skeletal muscle. Orthologous to human SMTNL1 (smoothelin like 1).
