ZNFN1A1 (DNA-binding Protein Ikaros, Ikaros Family Zinc Finger Protein 1, Lymphoid Transcription Factor LyF-1, IKZF1, IK1, IKAROS, LYF1)

Ikaros family proteins, characterized by the presence of N-terminal zinc finger DNA-binding domain and C-terminal dimerization domain, belong to the Kruppel transcription factor superfamily. Ikaros family includes Ikaros, Aiolos, Helios, and possibly EOS and Pegasus. They can form homodimers as well as heterdimers with other members of the Ikaros family. Due to differential splicing, multiple isoforms can be generated and some behave in a dominant negative manner upon dimerization. Ikaros, also known as IKZF1 (Ikaros family zinc finger protein 1) and LYF-1 (Lymphoid transcription factor 1), is expressed abundantly in blood cells. Genetic studies in mice demonstrate that Ikaros is important for the normal development of B, T, natural killer, and dendritic cells, and that it functions as a tumor suppressor. Imbalanced expression of different Ikaros isoforms as well as deletions of Ikaros are associated with hematologic malignancies in humans.\n\nApplications:\nSuitable for use in ELISA and Western Blot.
