产物介绍产补肠办驳谤辞耻苍诲:
The Ras-related superfamily of guanine nucleotide binding proteins includes the R-Ras, Rap, Ral/Rec and Rho/Rab subfamilies all of which are thought to play an important role in either endocytosis or in biosynthetic protein transport. The process of transporting newly synthesized proteins from the endoplasmic reticulum (ER) to various stacks of the Golgi complex and to secretory vesicles involves the movement of carrier vesicles and requires Rab protein function. Rab proteins are also an integral part of endocytic pathways. Rab 20 (Ras-related protein Rab-20) is a 234 amino acid protein that localizes to the golgi apparatus and belongs to the Rab subfamily of small GTPases. Expressed in normal and cancerous pancreatic tissue, Rab 20 plays an important role in apical endocytosis and recycling and may be involved in the development of exocrine pancreatic adenocarcinomas
Function:
Plays a role in apical endocytosis/recycling. Plays a role in the maturation and acidification of phagosomes that engulf pathogens, such as S.aureus and M.tuberculosis. Plays a role in the fusion of phagosomes with lysosomes.
Subcellular Location:
Golgi apparatus. Cytoplasmic vesicle, phagosome. Cytoplasmic vesicle, phagosome membrane; Lipid-anchor; Cytoplasmic side (By similarity). Note=Highly enriched on apical endocytic structures in polarized epithelial cells of kidney proximal tubules (By similarity). Recruited to phagosomes containing S.aureus or M.tuberculosis.
Tissue Specificity:
Low or absent expression in normal pancreas and stronger expression in 15 of 18 exocrine pancreatic adenocarcinomas (at protein level).
Similarity:
Belongs to the small GTPase superfamily. Rab family.

搁础叠20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。
搁础叠20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。
