Ionotropic glutamate receptors are categorized into NMDA receptors and kainate/AMPA receptors, both of which contain glutamate-gated, cation-specific ion channels. Kainate/AMPA receptors are co-localized with NMDA receptors in many synapses and consist of seven structurally related subunits designated GluR-1 to -7. The kainate/AMPA receptors are primarily responsible for the fast excitatory neuro-transmission by glutamate, whereas the NMDA receptors are functionally characterized by a slow kinetic and a high permeability for Ca2+ ions. The NMDA receptors consist of five subunits: epsilion 1, 2, 3, 4 and one zeta subunit. The zeta subunit is expressed throughout the brainstem, whereas the four epsilon subunits display limited distribution.Function : Ionotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L-glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist.Subunit : Homotetramer or heterotetramer of pore-forming glutamate receptor subunits. Tetramers may be formed by the dimerization of dimers. Interacts with EPB41L1 via its C-terminus (By similarity). Found in a complex with GRIA1, GRIA2, GRIA3, CNIH2, CNIH3, CACNG2, CACNG3, CACNG4, CACNG5, CACNG7 and CACNG8. Interacts with CACNG5 and PRKCGSubcellular Location : Cell membrane; Multi-pass membrane protein. Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein. Cell projection, dendrite. Note=Interaction with CNIH2, CNIH3 and PRKCG promotes cell surface expressionPost-translational modifications : Palmitoylated. Depalmitoylated upon glutamate stimulation. Cys-611 palmitoylation leads to Golgi retention and decreased cell surface expression. In contrast, Cys-837 palmitoylation does not affect cell surface expression but regulates stimulation-dependent endocytosis.Similarity : Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIA4 subfamily.Database links : UniProtKB/Swiss-Prot: P48058.2一抗和二坑的区别:
Anti-phospho-GluA4 (Ser862)抗体抗体就是平常所说的抗体,即能和抗原特异性结合。
第二抗体是能和抗体结合的,即抗体的抗体。主要用于检测抗体的存在。
一抗是针对抗原的抗体,二抗是针对一抗的抗体。即抗体也可以充当抗原刺激机体产生抗体。也就是说,抗原进入机体刺激机体免疫系统产生免疫应答,由B细胞可以产生与相应抗原发生特异性结合的特殊蛋白质。
一抗二抗都是一种可以特异结合别的物质的基团,而且一抗可以至少结合两种其他基团(底物和二抗)。
一抗:可以特异结合底物,就是识别出我们想要检测的东西。一抗和底物结合与否用肉眼是看不出来的。
二抗:可以和一抗结合,并带有可以被检测出的标记(如带荧光、放射性、化学发光或显色基团),作用是检测一抗。 如果一抗自己带有可以被检测出的标记(如带荧光、放射性、化学发光或显色基团),则不需要二抗。但这样成本很高,因为一种一抗只识别一种底物。所以如今的设计一般是二抗带上可检测标记,再来检测一抗。而一抗识别底物。这样,当一抗结合到底物上,就可以通过二抗检测出来。 抗体的制备过程:
1. 免疫原的制备
普通的大分子蛋白,通过分子克隆构建载体并在大肠杆菌中进行诱导表达获得重组蛋白,纯化鉴定后可直接作为免疫原。
小分子蛋白或化合物等分子量小,需要偶联载体对该分子进行改造才能使其成为具有免疫原性的抗原,常见偶联载体如BSA、OVA、HAS等。
2. 免疫动物
常用于制备抗血清的动物有豚鼠、家兔、鸡、大小鼠等,大量生产时需要用到狗、绵羊、山羊等。
3. 免疫血清的收集
一般家兔、绵羊、山羊可采用静动脉采血,家兔、豚鼠、大鼠、鸡可采用心脏采血,家兔、山羊、绵羊可采用静脉采血。
4. 免疫血清的纯化与鉴定
得到的抗血清需要进一步的纯化,利用偶联了抗原的亲和柱进行层析,具有GX,特异性强,纯度高的特定。接着要鉴定纯化蛋白的含量、相对分子的质量、纯度以及特异性。
5. 免疫血清的保存
建议分装后进行保存。抗体一般比较稳定,在-80℃ ~-20 ℃可以保存约5年而不会影响效价,而真空干燥保存时间可以更久。保存前需经CJ并添加防腐剂。抗体的生物素化标记实验要点:
1.如在反应混合液中有或游离氨基存在,会YZ标记反应。因此,蛋白质在反应前要对 0.1mol/L碳酸氢钠缓冲液或0.5mol/L硼酸缓冲液充分透析;
2.所用的NHSB及待生物素化蛋白质之间的分子比按蛋白质表面的ε-氨基的密度会有所不同,选择不当则影响标记的效率,应先用几个不同的分子比来筛选Z适条件;
3.用NHSB量过量也是不利的,抗原的结合位点可能因此被封闭,导致抗体失活;
4.由于抗体的氨基不易接近可能造成生物素化不足,此时可加入去污剂如 Triton x-100, Tween20等;
5.当游离ε-氨基(赖氨酸残基的氨基)存在于抗体的抗原结合位点时,或位于酶的催化位点时,生物素化会降低或损伤抗体蛋白的结合力或活性;
6.生物素还可能与不同的功能基团,如羰基、氨基、巯基、异咪唑基及苯酚基,也可与糖基共价结合;
7.交联反应后,应充分透析,否则,残余的生物素会对生物素化抗体与亲和素的结合产生竞争作用;
8.在细胞的荧光标记实验中,中和亲和素的本底低,但由于链霉亲和素含有少量正电荷,故对某些细胞可导致高本底。
