  • Experimental Validation Results for Aurora B Antibody (YA594)
    Western blot analysis of extracts from Hela (lane 1) and Jurkat (lane 2) using Aurora B antibody. Proteins were transferred to a PVDF membrane and blocked with 5% nonfat powdered milk in PBST for 2 hour at room temperature. The primary antibody (1/1000) and loading control antibody (GAPDH, 1/3000) was diluted with 5% nonfat powdered milk in PBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (1/8,000) was incubated for 45min at room temperature.

Background

  • Function

    Aurora B (AURKB) is a mitotic serine/threonine kinase and the enzymatic core of the chromosomal passenger complex (CPC)， which includes INCENP, Survivin, and Borealin[1]. Mechanistically, the CPC guides Aurora B through mitosis to control chromosome alignment, histone modification, kinetochore-microtubule error correction, spindle checkpoint signaling, and cytokinesis[1][2]. Therefore, Aurora B activity supports faithful chromosome segregation by releasing incorrect kinetochore-microtubule attachments, while reduced activity increases chromosome missegregation and aneuploid-cell generation[2]. In disease models, Aurora B deregulation or overexpression appears in several tumors, and studies in hepatocellular carcinoma, oral squamous cell carcinoma, prostate carcinoma, and glioblastoma connect Aurora B activity with recurrence, prognosis, tumor growth, or mitotic disruption[3][4][5][6]. Compared with related isoforms, Aurora A localizes to spindle poles and regulates mitotic entry, centrosome maturation, and spindle assembly, whereas Aurora B localizes with the CPC from inner centromeres to the spindle midzone and midbody[7]. Aurora C can act as a chromosomal passenger protein and complement Aurora B in mitotic cells, but Aurora B shows preferential INCENP binding and earlier M-phase expression[8]. For experimental applications, Aurora B or pan-Aurora inhibitors such as VX-680, AMG900, and danusertib help dissect metaphase-anaphase transition, cytokinetic initiation, mitotic progression, and cancer-cell proliferation[6][9][10].

  • Expression


    Tissue_specificity:It is highly expressed in the thymus. It is also expressed in the spleen, lungs, testes, colon, placenta, and fetal liver. It is expressed in the S phase and G2/M phase, and its expression is upregulated in M phase cancer cells; it is not expressed in normal liver, but is highly expressed in metastatic liver.

    Induction:Expression is cell cycle-regulated, with a low in G1/S, an increase during G2 and M. Expression decreases again after M phase

  • Isoforms & Post-Translational Modification

    Q96GD4 has 5 isomers: Q96GD4-1: 39311 Da (predicted); Q96GD4-2: 35302 Da (predicted); Q96GD4-3: 16211 Da (predicted); Q96GD4-4: 34760 Da (predicted); Q96GD4-5: 39467 Da (predicted).
    The phosphorylation of Thr-232 requires the binding to INCENP and occurs by means of an autophosphorylation mechanism (PubMed:14722118). Thr-232 phosphorylation is indispensable for the AURKB kinase activity (PubMed:14722118, PubMed:26829474);Acetylated at Lys-215 by KAT5 at kinetochores, increasing AURKB activity and promoting accurate chromosome segregation in mitosis;Ubiquitinated by different BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase complexes (PubMed:17543862, PubMed:19995937). Ubiquitinated by the BCR(KLHL9-KLHL13) E3 ubiquitin ligase complex, ubiquitination leads to removal from mitotic chromosomes and is required for cytokinesis (PubMed:17543862). During anaphase, the BCR(KLHL21) E3 ubiquitin ligase complex recruits the CPC complex from chromosomes to the spindle midzone and mediates the ubiquitination of AURKB (PubMed:17543862). Ubiquitination of AURKB by BCR(KLHL21) E3 ubiquitin ligase complex may not lead to its degradation by the proteasome (PubMed:19995937). Deubiquitinated by USP35; inhibiting CDH1-mediated degradation of AURKB (PubMed:29449677)
