有丝分裂检验点蛋白BubR1抗体产品介绍
Function : Essential component of the mitotic checkpoint. Required for normal mitosis progression. The mitotic checkpoint delays anaphase until all chromosomes are properly attached to the mitotic spindle. One of its checkpoint functions is to inhibit the activity of the anaphase-promoting complex/cyclosome (APC/C) by blocking the binding of CDC20 to APC/C, independently of its kinase activity. The other is to monitor kinetochore activities that depend on the kinetochore motor CENPE. Required for kinetochore localization of CENPE. Negatively regulates PLK1 activity in interphase cells and suppresses centrosome amplification. Also implicated in triggering apoptosis in polyploid cells that exit aberrantly from mitotic arrest. May play a role for tumor suppression.
Subunit : Interacts with CENPE, CENPF, mitosin, PLK1 and BUB3. Part of a complex containing BUB3, CDC20 and BUB1B. Interacts with anaphase-promoting complex/cyclosome (APC/C). Interacts with CASC5.
Subcellular Location : Cytoplasm. Nucleus. Chromosome, centromere, kinetochore. Cytoplasm, cytoskeleton, centrosome.
Tissue Specificity : Highly expressed in thymus followed by spleen. Preferentially expressed in tissues with a high mitotic index.
Post-translational modifications : Proteolytically cleaved by caspase-3 in a cell cycle specific manner. The cleavage might be involved in the durability of the cell cycle delay. Caspase-3 cleavage is associated with abrogation of the mitotic checkpoint. The major site of cleavage is at Asp-610.
Acetylation at Lys-250 regulates its degradation and timing in anaphase entry.
Ubiquitinated. Degraded by the proteasome.
Sumoylated with SUMO2 and SUMO3. The sumoylation mediates the association with CENPE at the kinetochore.
Autophosphorylated in vitro. Intramolecular autophosphorylation is stimulated by CENPE. Phosphorylated during mitosis and hyperphosphorylated in mitotically arrested cells. Phosphorylation at Ser-670 and Ser-1043 occurs at kinetochores upon mitotic entry with dephosphorylation at the onset of anaphase.
DISEASE : Note=Defects in BUB1B are associated with tumor formation.
Premature chromatid separation trait (PCS) [MIM:176430]:Consists of separate and splayed chromatids with discerniblecentromeres and involves all or most chromosomes of a metaphase. Itis found in up to 2% of metaphases in cultured lymphocytes fromapproximately 40% of normal individuals. When PCS is present in 5%or more of cells, it is known as the heterozygous PCS trait and hasno obvious phenotypic effect, although some have reported decreasedfertility. Inheritance is autosomal dominant. Note=The disease iscaused by mutations affecting the gene represented in this entry.
Mosaic variegated aneuploidy syndrome 1 (MVA1)[MIM:257300]: A severe developmental disorder characterized bymosaic aneuploidies, predominantly trisomies and monosomies,involving multiple different chromosomes and tissues. Affectedindividuals typically present with severe intrauterine growthretardation and microcephaly. Eye anomalies, mild dysmorphism,variable developmental delay, and a broad spectrum of additionalcongenital abnormalities and medical conditions may also occur. Therisk of malignancy is high, with rhabdomyosarcoma, Wilms tumor andleukemia reported in several cases. Note=The disease is caused bymutations affecting the gene represented in this entry. MVA1 iscaused by biallelic mutations in the BUB1B gene.
Similarity : Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. BUB1 subfamily.
Contains 1 BUB1 N-terminal domain.
Contains 1 protein kinase domain.
Database links : UniProtKB/Swiss-Prot: O60566.3
纯度：在实验的任何阶段，确定抗体溶液纯度的最简单方法是取一部分样本进行SDS-PAGE电泳。凝胶可用考马斯亮蓝染色(灵敏度为0.1—0.5ug/带)或银染(灵敏度1～l0ug/带)。
定量：如果抗体还不纯，有一个快捷的定量方法，即通过SDS-PAGE电泳分离出轻、重链，然后和已知的标准染色带比较。如果需要分析许多样本，用免疫测定法对抗体定量较容易。如果抗体是经过纯化的，可通过测蛋白总量代替上述两种方法，有一简单的方法，即紫外吸收法。有丝分裂检验点蛋白BubR1抗体的量可通过测280nm处的吸收值来测(10D大致相当于0.75mg/m1的纯化抗体)。
抗原结合活性：一般说来，纯化方法不会引起抗原结合活性的改变。用蛋白G或蛋白A树脂很少导致抗体活性丧失。然而，如果最终抗体产物的作用不如原来所预料的好，检测抗体纯化过程所丢失的活性就极为重要。用一系列滴定法比较纯化的抗体和其原材料的活性，以标定每一步中的总抗体量，这将有助于较好的估计通过纯化所丢失的活性。
