Anti-Galpha 12 antibodies are protein reagents that detect specific antigens. The Galpha 12 antigen is another term for the human protein G protein subunit alpha 12, encoded by the GNA12 gene. The protein is known to function in cell differentiation and GPCR signaling pathways, among other biological roles. Canonically, it has an amino acid length of 381 residues and a mass of 44.3 kilodaltons. Its subcellular localization is in the cell membrane and cytoplasm and it is widely expressed in many tissue types. The Galpha 12 protein is a member of the G-alpha protein family. Other alias names for Galpha 12 include HG1M1, NNX3, and RMP.
