Anti-LDS2 antibodies are protein reagents that detect specific antigens. The LDS2 antigen is another term for the human protein transforming growth factor beta receptor 2, encoded by the TGFBR2 gene. The protein is known to function in pathways of aging and the apoptotic pathway, among other biological roles. Canonically, it has an amino acid length of 567 residues and a mass of 64.6 kilodaltons. Its subcellular localization is in the cell membrane and is secreted. The LDS2 protein is a member of the TKL Ser/Thr protein kinase protein family.
