产品介绍 UAP56 belongs to the DEAD box family of RNA-dependent ATPases that mediate ATP hydrolysis during pre-mRNA splicing. UAP56 is an essential splicing factor required for association of U2 small nuclear ribonucleoprotein with pre-mRNA, and also plays an important role in mRNA export from the nucleus to the cytoplasm.

Function : [FUNCTION] Component of the THO subcomplex of the TREX complex. The TREX complex specifically associates with spliced mRNA and not with unspliced pre-mRNA. It is recruited to spliced mRNAs by a transcription-independent mechanism. Binds to mRNA upstream of the exon-junction complex (EJC) and is recruited in a splicing- and cap-dependent manner to a region near the 5' end of the mRNA where it functions in mRNA export. The recruitment occurs via an interaction between ALYREF/THOC4 and the cap-binding protein NCBP1. DDX39B functions as a bridge between ALYREF/THOC4 and the THO complex. The TREX complex is essential for the export of Kaposi's sarcoma-associated herpesvirus (KSHV) intronless mRNAs and infectious virus production. The recruitment of the TREX complex to the intronless viral mRNA occurs via an interaction between KSHV ORF57 protein and ALYREF/THOC4. Splice factor that is required for the first ATP-dependent step in spliceosome assembly and for the interaction of U2 snRNP with the branchpoint. Has both RNA-stimulated ATP binding/hydrolysis activity and ATP-dependent RNA unwinding activity. Even with the stimulation of RNA, the ATPase activity is weak. Can only hydrolyze ATP but not other NTPs. The RNA stimulation of ATPase activity does not have a strong preference for the sequence and length of the RNA. However, ssRNA stimulates the ATPase activity much more strongly than dsRNA. Can unwind 5' or 3' overhangs or blunt end RNA duplexes in vitro. The ATPase and helicase activities are not influenced by U2AF2 and ALYREF/THOC4.

Subunit : Homodimer, and heterodimer with DDX39A. Component of the THO complex, which is composed of THOC1, THOC2, THOC5, THOC6 and THOC7. Together with THOC3, ALYREF/THOC4 and DDX39B, THO forms the transcription/export (TREX) complex. Component of the spliceosome. Interacts directly with U2AF2. Interacts directly with ALYREF/THOC4 and is necessARy for ALYREF/THOC4 recruitment to spliced mRNA. Interacts with RBM8A, RNPS1 and SRRM1. Interacts with FYTTD1/UIF and THOC1. Interacts with human cytomegalovirus/HHV-5 protein UL69. Interacts with MX1.

抗体的生物素化标记实验要点：

1. ATP-依赖的RNA解旋酶p47抗体说明书 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。

抗体的鉴定：

1）ATP-依赖的RNA解旋酶p47抗体说明书 抗体的效价鉴定：不管是用于诊断还是用于,制备抗体的目的都是要求较高效价。不同的抗原制备的抗体,要求的效价不一。鉴定效价的方法很多,包括有试管凝集反应,琼脂扩散试验,酶联免疫吸附试验等。常用的抗原所制备的抗体一般都有约成的鉴定效价的方法,以资比较。如制备抗抗体的效价,一般就采用琼脂扩散试验来鉴定。

2）抗体的特异性鉴定：抗体的特异性是指与相应抗原或近似抗原物质的识别能力。抗体的特异性高,它的识别能力就强。衡量特异性通常以交叉反应率来表示。交叉反应率可用竞争抑制试验测定。以不同浓度抗原和近似抗原分别做竞争抑制曲线,计算各自的结合率,求出各自在IC50时的浓度,并按公式计算交叉反应率。 

如果所用抗原浓度IC50浓度为pg/管,而一些近似抗原物质的IC50浓度几乎是无穷大时,表示这一抗血清与其他抗原物质的交叉反应率近似为0,即该血清的特异性较好。

3）抗体亲和力：是指抗体和抗原结合的牢固程度。亲和力的高低是由抗原分子的大小,抗体分子的结合位点与抗原决定簇之间立体构型的合适度决定的。有助于维持抗原抗体复合物稳定的分子间力有氢键,疏水键,侧链相反电荷基因的库仑力,范德华力和空间斥力。亲和力常以亲和常数K表示,K的单位是L/mol。抗体亲和力的测定对抗体的筛选,确定抗体的用途,验证抗体的均一性等均有重要意义。
