Protein Structure

UniProt Annotation

Function

DNA-binding protein that 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. {ECO:0000269PubMed:10218586, ECO:0000269PubMed:17403896}.

Subcellular Localization

Nucleus.

Disease Associations

Tissue Specificity

Expressed mainly in the brain. Up-regulated in long term cultured astrocytes. Down-regulated during osteoclast differentiation. {ECO:0000269PubMed:10218586, ECO:0000269PubMed:17403896}.
