Anti-RMP antibodies enable researchers to detect and measure the RMP antigen in biological samples. This target is a reported synonym of the GNA12 gene, which encodes G protein subunit alpha 12. This protein is known to function in cell differentiation and GPCR signaling pathways, among other biological roles. The human version of RMP has a canonical amino acid length of 381 residues and a protein mass of 44.3 kilodaltons. It is reported to be localized in the cell membrane and cytoplasm of cells and widely expressed in many tissue types. RMP is a member of the G-alpha protein family.
