Anti-EGFR-RS antibodies enable researchers to detect and measure the EGFR-RS antigen in biological samples. This target is a reported synonym of the RHBDF1 gene, which encodes rhomboid 5 homolog 1. This protein is known to function in cell migration and cell proliferation, among other biological roles. The human version of EGFR-RS has a canonical amino acid length of 855 residues and a protein mass of 97.4 kilodaltons. It is reported to be localized in the ER and Golgi of cells. EGFR-RS is a member of the Peptidase S54 protein family.
