Zinc finger protein Eos (Ikzf4)

DNA-binding protein which binds to the 5'GGGAATRCC-3' Ikaros-binding sequence. Interacts with SPI1 and MITF to repress transcription of the CTSK and ACP5 promoters via recruitment of corepressors SIN3A and CTBP2.

May be involved in the development of central and peripheral nervous systems. Essential for the inhibitory function of regulatory T-cells (Treg).
