Anti-C3orf34 antibodies enable researchers to detect and measure the C3orf34 antigen in biological samples. This target is a reported synonym of the CEP19 gene, which encodes centrosomal protein 19. This protein is known to function in cilium assembly, among other biological roles. The human version of C3orf34 has a canonical amino acid length of 163 residues and a protein mass of 19.2 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the testis, hippocampus, cerebral cortex, cerebellum, and caudate. C3orf34 is a member of the CEP19 protein family.
