Anti-NYD-SP29 antibodies enable researchers to detect and measure the NYD-SP29 antigen in biological samples. This target is a reported synonym of the DNAI3 gene, which encodes dynein axonemal intermediate chain 3. This protein is known to function in the regulation of cell migration and osteoblast differentiation, among other biological roles. The human version of NYD-SP29 has a canonical amino acid length of 891 residues and a protein mass of 102.9 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and notably expressed in the fallopian tube and testis.
