- DNA-binding protein Ikaros
- Ikaros family zinc finger protein 1
背景信息 IKAROS, also known as IKZF1, is a transcription factor that is important for the regulation of lymphopoiesis and also the development of the immune system. It has also been linked to adult and fetal erythroid differentiation in humans. IKAROS has been shown to induce local chromatin accessibility during CD4+ T cell differentiation and therefore, activating Th2 expression. 产品信息 格式 Affinity Purified 控制 - HeLa cell lysate

UniProt汇总 FUNCTION: Transcription regulator of hematopoietic cell differentiation. Binds gamma-satellite DNA. Binds with higher affinity to gamma satellite A. 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 (terminal 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).
SUBUNIT STRUCTURE: Heterodimer with other IKAROS family members. Interacts with IKZF4 AND IKZF5 By similarity. 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 (By similarity).
SUBCELLULAR LOCATION: Nucleus. Note: In resting lymphocytes, distributed diffusely throughout the nucleus. Localizes to pericentromeric heterochromatin in proliferating cells. This localization requires DNA binding which is regulated by phosphorylation / dephosphorylation events (By similarity).
Isoform Ik2: Nucleus. Note: In resting lymphocytes, distributed diffusely throughout the nucleus. Localizes to pericentromeric heterochromatin in proliferating cells. This localization requires DNA binding which is regulated by phosphorylation / dephosphorylation events (By similarity).
Isoform Ik6: Cytoplasm (By similarity).
TISSUE SPECIFICTY: Abundantly expressed in thymus, spleen and peripheral blood Leukocytes and lymph nodes. Lower expression in bone marrow and small intestine.
DOMAIN: The N-terminal zinc-fingers 2 and 3 are required for DNA binding as well as for targeting IKFZ1 to pericentromeric heterochromatin (By similarity).
The C-terminal zinc-finger domain is required for dimerization (By similarity).
PTM: Phosphorylation controls cell-cycle progression from late G1 stage to S stage. Hyperphosphorylated during G2/M phase. Dephosphorylated state during late G1 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).
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).
Polyubiquitinated (By similarity).
INVOLVEMENT IN DISEASE: Note=Defects in IKZF1 are frequent occurrences (28.6%) in acute lymphoblasic leukemia (ALL). Such alterations or deletions lead to poor prognosis for ALL.
SEQUENCE SIMILARITIES: Belongs to the Ikaros C2H2-type zinc-finger protein family.
Contains 6 C2H2-type zinc fingers.产品使用声明 质量保证 Evaluated by Western Blot in HeLa cell lysate.
