Recombinant human IKZF4 protein, also known as Aiolos, is a functionally engineered variant of the naturally occurring transcription factor belonging to the IKAROS family of zinc finger DNA-binding proteins. First identified in the 1990s, IKZF4 plays a pivotal role in immune regulation and lymphocyte development. Structurally, it contains N-terminal zinc finger motifs critical for DNA binding and homo-/heterodimerization with family members like IKZF1 (Ikaros), and a C-terminal domain involved in chromatin remodeling through interactions with histone deacetylases (HDACs).
IKZF4 is highly expressed in differentiated lymphocytes, particularly in T and B cells, where it modulates gene expression linked to immune activation, proliferation, and apoptosis. Dysregulation of IKZF4 has been implicated in autoimmune diseases, leukemia, and solid tumors, with overexpression observed in certain cancers correlating with poor prognosis. Its role in immune evasion mechanisms has recently drawn attention in immunotherapy research.
The recombinant form is typically produced in mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications, though prokaryotic systems are occasionally used for structural studies. Purification via affinity tags enables applications in biochemical assays, antibody production, and mechanistic studies exploring its interactions with target genes. As a research tool, recombinant IKZF4 facilitates investigations into transcriptional regulation pathways and therapeutic targeting of IKZF4-associated pathologies. Current challenges include clarifying context-dependent functional variations and developing selective modulators for clinical translation.
