Ikaros Transcription Factor (IKZF1)

Target
IKZF1
Molecular classification
Transcription factor, Zinc finger protein, DNA-binding protein
01

Overview

Ikaros (IKZF1) is a zinc-finger DNA-binding protein and transcription factor crucial for hematopoiesis and immune cell development, especially in B cells and CD4+ T cells. It functions as both a transcriptional activator and repressor through cofactor interactions and chromatin modification. Dysfunction is linked to leukemia, particularly B-cell ALL, and other immune disorders. It regulates the expression of key genes involved in immune cell differentiation and cytokine production.

Other names
Ikaros family zinc finger protein 1
