Anti-CD307c antibodies enable researchers to detect and measure the CD307c antigen in biological samples. This target is a reported synonym of the FCRL3 gene, which encodes Fc receptor like 3. This protein is known to function in receptor-mediated signaling pathways and MAPK cascade signaling pathways, among other biological roles. The human version of CD307c has a canonical amino acid length of 734 residues and a protein mass of 80.9 kilodaltons, although 7 isoforms have been identified. It is reported to be localized in the cell membrane of cells.
