产物介绍产补肠办驳谤辞耻苍诲:
The protein encoded by this gene is a guanine nucleotide exchange factor (GEF) similar to the Saccharomyces cerevisiae CDC25 gene product. Functional analysis has demonstrated that this protein stimulates the dissociation of GDP from RAS protein. The studies of the similar gene in mouse suggested that the Ras-GEF activity of this protein in brain can be activated by Ca2+ influx, muscarinic receptors, and G protein beta-gamma subunit. Mouse studies also indicated that the Ras-GEF signaling pathway mediated by this protein may be important for long-term memory. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Mar 2009]
Function:
Promotes the exchange of Ras-bound GDP by GTP.
Subunit:
Homooligomer and heterooligomer with RASGRF2. Interacts with USP8, thereby regulating its stability.
Post-translational modifications:
Phosphorylated by PLK2, leading to ubiquitination and degradation by the proteasome.
Ubiquitinated and degraded following phosphorylation by PLK2 By similarity).
Phosphorylated by SRC and LCK. Phosphorylation by LCK increases its capacity to stimulate the GDP/GTP exchange on Ras, whereas its phosphorylation by SRC seems not to have an effect on stimulation activity.
Similarity:
Contains 1 DH (DBL-homology) domain.
Contains 1 IQ domain.
Contains 1 N-terminal Ras-GEF domain.
Contains 2 PH domains.
Contains 1 Ras-GEF domain.
Gene ID:
5923
Phospho-RASGRF1 (Ser916)抗体(antibody,
Ab)是由效应B细胞(效应**B细胞)分泌,机体用于抵御外来物质,如病毒,**等抗原,结构呈“驰”字型的球状蛋白质,仅仅存在于脊椎动物的血液和B**细胞膜表面。凡是能够跟抗体结合的物质,均被称作抗原,因此对于抗抗体(能够结合抗体的抗体)来说,抗体本身也是一种抗原物质。
Phospho-RASGRF1 (Ser916)抗体普通抗体重链和轻链的结构
重链结构:普通的**球蛋白具有2条重链(H链),分子量约为50kD,有μ、δ、γ、ε和α五种重链亚型,对应的**球蛋白名称分别为IgM、IgG、IgA、IgD和IgE。
轻链结构: 普通**球蛋白具有2条轻链(L链),分子质量约25kDa,有κ链和λ链两种亚型,这两种轻链决定了Ig的亚型类别(IgG1,IgG2,IgG3,IgG4)。一个天然的Ig分子两条轻链总是相同的,但在同一个体内可存在分别带有κ或λ链的抗体分子。不同种属生物体内两型轻链的比例不同,正常人血清**球蛋白κ链:λ链约为2:1,而在小鼠的比例为20:1。
2.2抗体Fab段和Fc段
滨驳骋经木瓜蛋白酶酶切后裂解为2个完全相同的Fab段和1个Fc段,每个Fab段都为单价,可与抗原结合但不会再发生凝集反应;经胃蛋白酶酶切后裂解为1个完整F(ab)2片段和碎片化的Fc片段,F(ab’)2片段为双价,可同时结合两个抗原表位。Fab段为抗原结合片段(fragment of antigen binding,Fab),相当于抗体分子的两个臂,由一个完整的轻链和重链的VH和CH1结构域组成。Fc段为可结晶段(fragment crystallizable,Fc)相当于Ig的CH2和CH3结构域,是Ig与效应分子或者细胞相互作用的部位。Fab段包含完整的可变区,以及恒定区的CH1区域。Fc段仅指Ig恒定区CH2和CH3的区域,相当于Y字结构下面那一部分。
