产品介绍 This gene encodes the receptor for both luteinizing hormone and choriogonadotropin. This receptor belongs to the G-protein coupled receptor 1 family, and its activity is mediated by G proteins which activate adenylate cyclase. Mutations in this gene result in disorders of male secondary sexual character development, including familial male precocious puberty, also known as testotoxicosis, hypogonadotropic hypogonadism, Leydig cell adenoma with precocious puberty, and male pseudohermaphtoditism with Leydig cell hypoplasia. [provided by RefSeq]
Function : Receptor for lutropin-choriogonadotropic hormone. The activity of this receptor is mediated by G proteins which activate adenylate cyclase.
Subcellular Location : Cell membrane; Multi-pass membrane protein.
Tissue Specificity : Gonadal and thyroid cells.
DISEASE : Familial male precocious puberty (FMPP) [MIM:176410]: In FMPP the receptor is constitutively activated. Note=The disease is caused by mutations affecting the gene represented in this entry.
Luteinizing hormone resistance (LHR) [MIM:238320]: An autosomal recessive disorder characterized by unresponsiveness to luteinizing hormone, defective sexual development in males, and defective follicular development and ovulation, amenorrhea and infertility in females. Two forms of the disorder have been defined in males. Type 1 is a severe form characterized by complete 46,XY male pseudohermaphroditism, low testosterone and high luteinizing hormone levels, total lack of responsiveness to luteinizing and chorionic gonadotropin hormones, lack of breast development, and absent development of secondary male sex characteristics. Type 2, a milder form, displays a broader range of phenotypic expression ranging from micropenis to severe hypospadias. Note=The disease is caused by mutations affecting the gene represented in this entry.
Similarity : Belongs to the G-protein coupled receptor 1 family. FSH/LSH/TSH subfamily.
Contains 6 LRR (leucine-rich) repeats.
Contains 1 LRRNT domain.
Database links : UniProtKB/Swiss-Prot: P22888.4

抗体的生活习性:
(1)结合特异性抗原:抗体与其他免疫球蛋白分子区别,就在于抗体能与相应抗原发生特异性结合,在体内导致生理或病理效应;在体外产生各种直接或间接的可见的抗原抗体结合反应。抗体是靠其分子上的特殊的结合部位与抗原结合的。
(2)激活补体:抗体与相应抗原结合后,借助暴露的补体结合点去激活补体系统、激发补体的溶菌、溶细胞等免疫作用。
(3)结合细胞:不同类别的免疫球蛋白,可结合不同种的细胞,产生不同的疚,参与免疫应答。
(4)可通过胎盘及粘膜:免疫球蛋白G(IgG)能通过胎盘进入胎儿血流中,使胎儿形成自然被动免疫。免疫球蛋白A(IgA)可通过消化道及呼吸道粘膜,是粘膜局部抗感染免疫的主要因素。
(5)具有抗原性:抗体分子是一种蛋白质,也具有刺激机体产生免疫应答的性能。不同的免疫球蛋白分子,各具有不同的抗原性。
(6)抗体对理化因子的抵抗力与一般球蛋白相同:不耐热,60~70℃即被破坏。各种酶及能使蛋白质凝固变性的物质,均能破坏抗体的作用。抗体可被中性盐类沉淀。在生产上常可用硫酸铵或硫酸钠从免疫血清中沉淀出含有抗体的球蛋白,再经透析法将其纯化。
一抗和二坑的区别:
第一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。

抗体的生物素化标记实验要点:
1.如在反应混合液中有叠氮钠或游离氨基存在,会抑制标记反应。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最适条件;
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。
