Entrez Gene Summary for IKZF1 Gene

  • This gene encodes a transcription factor that belongs to the family of zinc-finger DNA-binding proteins associated with chromatin remodeling. The expression of this protein is restricted to the fetal and adult hemo-lymphopoietic system, and it functions as a regulator of lymphocyte differentiation. Several alternatively spliced transcript variants encoding different isoforms have been described for this gene. Most isoforms share a common C-terminal domain, which contains two zinc finger motifs that are required for hetero- or homo-dimerization, and for interactions with other proteins. The isoforms, however, differ in the number of N-terminal zinc finger motifs that bind DNA and in nuclear localization signal presence, resulting in members with and without DNA-binding properties. Only a few isoforms contain the requisite three or more N-terminal zinc motifs that confer high affinity binding to a specific core DNA sequence element in the promoters of target genes. The non-DNA-binding isoforms are largely found in the cytoplasm, and are thought to function as dominant-negative factors. Overexpression of some dominant-negative isoforms have been associated with B-cell malignancies, such as acute lymphoblastic leukemia (ALL). [provided by RefSeq, May 2014]

GeneCards Summary for IKZF1 Gene

IKZF1 (IKAROS Family Zinc Finger 1 (Ikaros)) is a Protein Coding gene. Diseases associated with IKZF1 include pancytopenia due to ikzf1 mutations and lymphoblastic leukemia. Among its related pathways are Calcineurin-regulated NFAT-dependent transcription in lymphocytes and Lymphocyte Signaling. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and protein heterodimerization activity. An important paralog of this gene is IKZF2.

UniProtKB/Swiss-Prot for IKZF1 Gene

  • Transcription regulator of hematopoietic cell differentiation (PubMed:17934067). Binds gamma-satellite DNA (PubMed:17135265, PubMed:19141594). Plays a role in the development of lymphocytes, B- and T-cells. Binds and activates the enhancer (delta-A element) of the CD3-delta gene. Repressor of the TDT (fikzfterminal deoxynucleotidyltransferase) gene during thymocyte differentiation. Regulates transcription through association with both HDAC-dependent and HDAC-independent complexes. Targets the 2 chromatin-remodeling complexes, NuRD and BAF (SWI/SNF), in a single complex (PYR complex), to the beta-globin locus in adult erythrocytes. Increases normal apoptosis in adult erythroid cells. Confers early temporal competence to retinal progenitor cells (RPCs) (By similarity). Function is isoform-specific and is modulated by dominant-negative inactive isoforms (PubMed:17135265, PubMed:17934067).

    • Heterodimer formed by the various isoforms; this modulates transcription regulator activity (PubMed:17135265, PubMed:17934067). Heterodimer with other IKAROS family members. Interacts with IKZF4 AND IKZF5 (PubMed:10978333). Component of the chromatin-remodeling NuRD repressor complex which includes at least HDAC1, HDAC2, RBBP4, RBBP7, IKZF1, MTA2, MBD2, MBD3, MTA1L1, CHD3 and CHD4. Interacts directly with the CHD4 component of the NuRD complex. Component of the BAF (SWI/SNF) gene activator complex which includes ACTB, ARID1A, ARID1B, IKZF1, ARID1A, ARID1B, SMARCA2, SMARCA4 and at least one BAF subunit. Interacts directly with the SMARCA4 component of the BAF complex (By similarity). Interacts with SUMO1; the interaction sumoylates IKAROS, promoted by PIAS2 and PIAS3. Interacts with PIAS2 (isoform alpha); the interaction promotes sumoylation and reduces transcription repression. Interacts, to a lesser extent, with PIAS3. Interacts with PPP1CC; the interaction targets PPP1CC to pericentromeric heterochromatin, dephosphorylates IKAROS, stabilizes it and prevents it from degradation. Interacts with IKZF3 (By similarity).

Post-translational modifications for IKZF1 Gene

  • Phosphorylation controls cell-cycle progression from late G(1) stage to S stage. Hyperphosphorylated during G2/M phase. Dephosphorylated state during late G(1) phase. Phosphorylation on Thr-140 is required for DNA and pericentromeric location during mitosis. CK2 is the main kinase, in vitro. GSK3 and CDK may also contribute to phosphorylation of the C-terminal serine and threonine residues. Phosphorylation on these C-terminal residues reduces the DNA-binding ability. Phosphorylation/dephosphorylation events on Ser-13 and Ser-295 regulate TDT expression during thymocyte differentiation. Dephosphorylation by protein phosphatase 1 regulates stability and pericentromeric heterochromatin location. Phosphorylated in both lymphoid and non-lymphoid tissues (By similarity). Phosphorylation at Ser-361 and Ser-364 downstream of SYK induces nuclear translocation.
  • Polyubiquitinated.
  • Sumoylated. Simulataneous sumoylation on the 2 sites results in a loss of both HDAC-dependent and HDAC-independent repression. Has no effect on pericentromeric heterochromatin location. Desumoylated by SENP1 (By similarity).
  • Modification sites at PhosphoSitePlus
  • Ubiquitination at Lys157, Lys286, Lys301, Lys378, and Lys460
