Target intelligence / Profile preview

IKAROS family zinc finger 3 (IKZF3)

Target
IKZF3
Molecular classification
Transcription factor, Zinc finger protein
01

Overview

IKZF3 encodes a hematopoietic-specific transcription factor belonging to the Ikaros family of zinc-finger proteins. It plays a crucial role in regulating B lymphocyte proliferation, differentiation, and maturation. The protein is also involved in chromatin remodeling and regulates gene expression in B lymphocytes through complex dimerization patterns. Dysregulation or mutation of IKZF3 has been associated with hematological malignancies, primary immunodeficiency disorders, and autoimmune diseases.
