Anti-Ccdc42b antibodies enable researchers to detect and measure the Ccdc42b antigen in biological samples. This target is a reported synonym of the CFAP73 gene, which encodes cilia and flagella associated protein 73. This protein is known to function in spermatid development, among other biological roles. The human version of Ccdc42b has a canonical amino acid length of 308 residues and a protein mass of 35.9 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the nasopharynx, fallopian tube, and bronchus. Ccdc42b is a member of the CFAP73 protein family.
