Anti-family with sequence similarity 154, member A antibodies enable researchers to detect and measure the family with sequence similarity 154, member A antigen in biological samples. This target is a reported synonym of the SAXO1 gene, which encodes stabilizer of axonemal microtubules 1. This protein is known to function in protein stabilization, among other biological roles. The human version of family with sequence similarity 154, member A has a canonical amino acid length of 474 residues and a protein mass of 54.6 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the fallopian tube and testis. Other names for this target antigen include 4930500O09Rik and family with sequence similarity 154, member A.
