Anti-Rlp49 antibodies enable researchers to detect and measure the Rlp49 antigen in biological samples. This target is a reported synonym of the RCN3 gene, which encodes reticulocalbin 3. This protein is known to function in protein transport, among other biological roles. The human version of Rlp49 has a canonical amino acid length of 328 residues and a protein mass of 37.5 kilodaltons. It is reported to be localized in the ER of cells. Rlp49 is a member of the CREC protein family.
