Summary: 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 peptidyl-serine phosphorylation; 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
