Anti-CHASM antibodies enable researchers to detect and measure the CHASM antigen in biological samples. This target is a reported synonym of the SMTNL1 gene, which encodes smoothelin like 1. This protein is known to function in cytoskeleton organization and the regulation of transcription, among other biological roles. The human version of CHASM has a canonical amino acid length of 494 residues and a protein mass of 53 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. CHASM is a member of the Smoothelin protein family.
