亚单元:
Homohexamer; in absence of calcium (PubMed:24514027). Forms a homohexamer in absence of calcium and rearranges into a heterodimer in presence of calcium (PubMed:26489515, PubMed:24514027). Heterodimer; disulfide-linked; heterodimerizes with MICU2 (PubMed:24560927). The heterodimer formed with MICU2 associates with MCU at low calcium concentration and dissociates from MCU at high calcium level (PubMed:26387864). Component of the uniplex complex, composed of MCU, MCUB, MICU1, MICU2 and EMRE/SMDT1 (PubMed:24231807). Interacts (via polybasic region) with EMRE/SMDT1; the interaction is direct (PubMed:27099988). Interacts (via polybasic region) with MCU (via coiled coil domains); the interaction is direct and precedes formation of the heterodimer with MICU2 (PubMed:21685886, PubMed:23101630, PubMed:23178883, PubMed:24332854, PubMed:26387864). Interacts with SLC25A23 (PubMed:24430870). Interacts with CHCHD4/MIA40; which introduces the interchain disulfide bond with MICU2 (PubMed:26387864).
功能:
Key regulator of mitochondrial calcium uniporter (MCU) that senses calcium level via its EF-hand domains (PubMed:20693986, PubMed:23101630, PubMed:23747253, PubMed:24313810, PubMed:24332854, PubMed:24503055, PubMed:24560927, PubMed:26341627, PubMed:26903221, PubMed:27099988). MICU1 and MICU2 form a disulfide-linked heterodimer that stimulates and inhibits MCU activity, depending on the concentration of calcium. MICU1 acts both as an activator or inhibitor of mitochondrial calcium uptake (PubMed:26903221). Acts as a gatekeeper of MCU at low concentration of calcium, preventing channel opening (PubMed:26903221). Enhances MCU opening at high calcium concentration, allowing a rapid response of mitochondria to calcium signals generated in the cytoplasm (PubMed:24560927, PubMed:26903221). Regulates glucose-dependent insulin secretion in pancreatic beta-cells by regulating mitochondrial calcium uptake (PubMed:22904319). Induces T-helper 1-mediated autoreactivity, which is accompanied by the release of IFNG (PubMed:16002733).
亚细胞位置:
Mitochondrion inner membrane
Single-pass membrane protein
Mitochondrion intermembrane space
The topology is subject to discussion. According to some reports, localizes at the outer surface of the mitochondrion inner membrane (PubMed:20693986, PubMed:24332854). According to another publication, forms a intramembrane hairpin loop without crossing the membrane (PubMed:23747253). Recent studies rather suggest that it contains a transmembrane region that crosses the mitochondrial inner membrane, with the main part of the protein localized in the mitochondrial intermembrane space (PubMed:26387864, PubMed:26489515).

人钙吸收蛋白1,线粒体(MICU1)ELISA试剂盒原理?
双抗体夹心法:用纯化的抗体包被微孔板,制成固相抗体,往包被有固相抗体的微孔中依次加入标准品或受检样本、生物素化抗体、HRP标记的亲和素,经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值),计算样本浓度。
竞争法:用纯化的抗体包被微孔板,制成固相抗体,往包被有固相抗体的微孔中依次加入标准品或受检样本和生物素标记的目标分析物,受检标本中抗原与生物素标记抗原竞争结合有限的抗体。再加入HRP标记的亲和素,经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值),计算样本浓度。

人钙吸收蛋白1,线粒体(MICU1)ELISA试剂盒中需要使用的样品量是多少?
夹心法100μL/孔,竞争法50μL/孔。如样本浓度过高时,应对样本进行稀释,以使稀释后的样本符合试剂盒的检测范围,计算时再乘以相应的稀释倍数。
[6].
如何分析人钙吸收蛋白1,线粒体(MICU1)ELISA试剂盒数据?
建议标准曲线,并计算样本浓度。对于elisa的曲线拟合,一般建议采用4参数曲线拟合,4参数曲线拟合通常更适合免疫分析。推荐使用专业软件进行曲线拟合,例如curve expert 1.3。根据样本的OD值由标曲查出相应的浓度,再乘以稀释倍数;或用标准物的浓度与OD值计算出标曲的回归方程式,将样本的OD值代入方程式,计算出样本浓度,再乘以稀释倍数,即为样本的实际浓度。以下链接是curve expert 1.3软件拟合曲线的方法。
