Anti-SYN47 antibodies are protein reagents that detect specific antigens. The SYN47 antigen is another term for the human protein homer scaffold protein 1, encoded by the HOMER1 gene. The protein is known to function in chemical synaptic transmission and the transport of ions, among other biological roles. Canonically, it has an amino acid length of 354 residues and a mass of 40.3 kilodaltons. Its subcellular localization is in the cytoplasm and it is expressed in the kidney, hippocampus, cerebral cortex, cerebellum, and caudate. The SYN47 protein is a member of the Homer protein family. Other alias names for SYN47 include HOMER, HOMER1A, and HOMER1B.
