Anti-smoothelin like 2 antibodies are used in the immunodetection of the protein encoded by the SMTNL2 gene. In humans, the canonical protein has a reported length of 461 amino acid residues and a mass of 50.2 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Smoothelin protein family, it is known to be involved with cytoskeleton organization. Other names for this target antigen include smoothelin-like protein 2.
