IKZF3 Antibody – Rabbit Polyclonal

This gene encodes a member of the Ikaros family of zinc-finger proteins. Three members of this protein family (Ikaros, Aiolos and Helios) are hematopoietic-specific transcription factors involved in the regulation of lymphocyte development. This gene product is a transcription factor that is important in the regulation of B lymphocyte proliferation and differentiation. Both Ikaros and Aiolos can participate in chromatin remodeling. Regulation of gene expression in B lymphocytes by Aiolos is complex as it appears to require the sequential formation of Ikaros homodimers, Ikaros/Aiolos heterodimers, and Aiolos homodimers. Several alternative transcripts encoding different isoforms have been described, as well as some non-protein coding variants. [provided by RefSeq, Apr 2012]

Aiolos: a transcription factor of the ikaros C2H2-type zinc-finger protein family. Plays an important role in the regulation of lymphocyte differentiation. Deletions in Aiolos have been observed in a subset of pre-B-cell acute lymphoblastic leukemia (B-ALL) cases. 6 isoforms of the human protein are produced by alternative splicing.
