促凋亡调节蛋白BNIP3抗体产品介绍 Apoptosis-inducing protein that, which can overcome BCL2 suppression. May play a role in repartitioning calcium between the two major intracellular calcium stores in association with BCL2.
Function : Apoptosis-inducing protein that can overcome BCL2 suppression. May play a role in repartitioning calcium between the two major intracellular calcium stores in association with BCL2. Involved in mitochondrial quality control via its interaction with SPATA18/MIEAP: in response to mitochondrial damage, participates to mitochondrial protein catabolic process (also named MALM) leading to the degradation of damaged proteins inside mitochondria. The physical interaction of SPATA18/MIEAP, BNIP3 and BNIP3L/NIX at the mitochondrial outer membrane regulates the opening of a pore in the mitochondrial double membrane in order to mediate the translocation of lysosomal proteins from the cytoplasm to the mitochondrial matrix. Plays an important role in the calprotectin (S100A8/A9)-induced cell death pathway.
Subunit : Homodimer. Binds to BCL2. Interacts with BNIP3L and ACAA2. Also can interact with adenovirus E1B 19 kDa protein or Epstein-Barr virus BHRF1. Interacts (via BH3 domain) with SPATA18 (via coiled-coil domains).
Subcellular Location : Mitochondrion. Mitochondrion membrane. Coexpression with the EIB 19-kDa protein results in a shift in NIP3 localization pattern to the nuclear envelope. Colocalizes with ACAA2 in the mitochondria.
Similarity : Belongs to the NIP3 family.
BNIP3蛋白在缺氧条件下可诱导细胞发生细胞凋亡。BNIP3促细胞凋亡线粒体途径根据有无caspase的参与而具有不同的作用机制,也是研究的热点。BNIP3还可诱导细胞自噬。BNIP3全称为Bcl2/腺病毒E1B19kD相互作用蛋白3。(Bcl2/adenovirusE1B19kDainteractingprotein3,BNIP3),是新近发现的BH3only亚家族成员之一,也是低氧敏感的凋亡基因。在化学性低氧诱导细胞凋亡的过程中,ATP是BNIP3导致细胞凋亡的关键性因素之一。单独ATP下降不诱导细胞凋亡,但ATP下降到一定程度能促进BNIP3向线粒体转位,从而诱导了BNIP3相关的凋亡。这可能是低氧诱导BNIP3表达导致细胞凋亡的重要机制之一。
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。促凋亡调节蛋白BNIP3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。
