Anti-DEAH-box helicase 57 antibodies enable researchers to detect and measure the DEAH-box helicase 57 antigen in biological samples. This target is a reported synonym of the DHX57 gene, which encodes DExH-box helicase 57. This protein is a suspected ATP-binding RNA helicase. The human version of DEAH-box helicase 57 has a canonical amino acid length of 1386 residues and a protein mass of 155.6 kilodaltons, although 3 isoforms have been identified. DEAH-box helicase 57 is a member of the DEAD box helicase protein family.
