Anti-PEGASUS antibodies enable researchers to detect and measure the PEGASUS antigen in biological samples. This target is a reported synonym of the IKZF5 gene, which encodes IKAROS family zinc finger 5. This protein is known to function in the regulation of transcription, among other biological roles. The human version of PEGASUS has a canonical amino acid length of 419 residues and a protein mass of 46.5 kilodaltons. It is reported to be localized in the nucleus of cells. PEGASUS is a member of the Ikaros C2H2-type zinc-finger protein family.
