Anti-SWS antibodies are protein reagents that detect specific antigens. The SWS antigen is another term for the human protein G protein subunit alpha q, encoded by the GNAQ gene. The protein is known to function in GPCR signaling pathways and protein stabilization, among other biological roles. Canonically, it has an amino acid length of 359 residues and a mass of 42.1 kilodaltons. Its subcellular localization is in the nucleus, Golgi, and cell membrane and it is reported to be highly expressed in the ovary, prostate, testis and colon. The SWS protein is a member of the G-alpha protein family.
