Predicted to enable several functions, including calmodulin binding activity; protein domain specific binding activity; and protein phosphatase 1 binding activity. Predicted to be involved in actin cytoskeleton organization; negative regulation of transcription, DNA-templated; and positive regulation of vasoconstriction. Predicted to act upstream of or within several processes, including peptidyl-serine phosphorylation; response to activity; and vasoconstriction. Predicted to be located in contractile fiber and nucleus. Predicted to be part of filamentous actin. Predicted to be active in I band; M band; and microtubule organizing center. Orthologous to human SMTNL1 (smoothelin like 1). [provided by Alliance of Genome Resources, Apr 2022]
