摘要肌動蛋白在真核生物中廣泛存在,由肌動蛋白參與形成的動態微絲骨架系統是細胞生命活動的基礎。Studies revealed that p - catenin dissociated from ccc and translocated into free catenin pool in cytosol after it has been phosphorylated at tyrosine or serine residues, and in this situation, the ccc has been disrupted and cell adhesion function disturbed. a large amount of the free p - catenins in the cytosol can be degraded by the tumor suppressor apc, and the remains translocate into nucleus and bind to transcriptional factor tcf / lef in the nucleus and then promote cell proliferation related gene or anti - apoptosis gene transcription
當-連環蛋白酪氨酸或絲氨酸殘基磷酸化后,就與ajs發生解離而游離到細胞漿中,此時細胞的粘附功能也發生障礙,游離到胞漿中的-連環蛋白,一部分被抑癌因子apc降解,一部分則轉移到細胞核內,與核內的轉錄因子tcf lef結合,啟動與細胞增殖有關的基因轉錄。The full orp encodes a 487 - amino acid protein with a calculated molecule weight of 53. 484 kda and an isoelectric point of 6. 75. at the primary sequence level, it shared high homology with clr, so was named clr - like serine protease, clsp. the clsp sequence has been submitted to genbank / embl ( genbank accession number af178985 )
該蛋白在核酸和氨基酸水平上與人補體組分cl :表現高度同源,故將其命名為補體cl :樣絲氨酸蛋白酶(旦lr一like旦erineprotease , clsp ) ,該基因已經在ge心ank登錄(登錄號為af17s985 ) 。Actin is a high - conserved protein with a wb of 43kd, aniversally exists in eucaryotic cell. f - actin is polymerized by g - actin which participates the formation of the netlike protein system of the complex skeleton in the eucaryotic cell
微絲( f - actin )是由肌動蛋白單體( g - actin )聚合形成的,它參與了真核細胞中復雜的細胞骨架網狀蛋白體系的形成。Global or filament actin was visualized in cytoplasm and nucleus of tobacco pollen mother cells, under immunoelectron microscope
免疫電鏡觀察發現,花粉母細胞中的細胞質及核中存在線狀和粒狀的肌動蛋白微絲。In this paper, the effect of nuclear actin on the process of chromosome construction has been studied by utilizing the precise natural synchrous plasmodium of physarum polycephalum, sds - polyacryl amide gel electrophoresis ( sds - page ), western blotting, the cell - free system and optics microscopy. the major results and conclusions are as follows : 1
本實驗以多頭絨泡菌原質團為材料,採用同步化培養、細胞核提取、 sds - page 、免疫印跡、非細胞體系構建、光學顯微鏡觀察等方法,研究了有絲分裂前期核內肌動蛋白對染色體構建的影響。Actin, the major component of the dynamic microfilaments system, exists in nearly all eukaryotic cells, and plays an essential role in living activities
肌動蛋白在真核生物中廣泛存在,由肌動蛋白參與形成的動態微絲骨架系統是細胞生命活動的基礎。The kinase catalytic domain is 264 amino acids in length and contains all of 11 conserved subdomains and 15 invariant amino acid residues essential fo r eukaryotic serine / threonine protein kinases
激酶區長264個氨基酸殘基,具有所有11個保守的亞結構域和15個對于真核生物絲氨酸蘇氨酸蛋白激酶所必需的保守的氨基酸殘基。Many cell signal transduction pathways have been discovered in the regulation of apoptotic induction and reduction. mito - gen - activated protein kinase ( mapk ) is a group of particular ser / thr protein kinases which are activated when its conservative thr and tyr residues are both phosphorylated by upstream mapk kinases
絲裂原活化蛋白激酶( mapk )是一群特殊的絲蘇氨酸蛋白激酶,它通過其上游mapkk使其保守的蘇氨酸和酪氨酸殘基雙磷酸化而活化,活化的mapk可轉移到核內,參與基因表達調控。Cultured epithelial cell undergoing division. this cell is in prophase of mitosis. microtubules are shown in green, actin is in red and mitotic chromosomes are colored blue
以上兩圖為正處于有絲分裂前期的動物上皮細胞。綠色的是微絲,紅色為肌動蛋白,染色質高度螺旋成為粗短的染色體(藍色) ,核膜核仁逐漸解體,染色體不規則地分佈於細胞內。It possess high homology with those of ck2 ( casein kinase 2 ) a subunits from various species. it is now well established that protein kinase ck2 is a pleiotropic and abiquitous serine or threonine kinase, which is highly conserved during evolution. we obtained the complete cdna sequence of ck2 a via 5 " race
酪蛋白激酶ck2是目前發現的普遍存在於真核生物中的絲氨酸蘇氨酸型蛋白激酶,進化上具有高度的保守性並參與了多種生理功能的調控,因而克隆它的基因具有重要意義。As cyclin b is the mark protein representing the process of prophase, we infered that cytochalasin b destroyed the polymerization of the nuclear actin and directly affected the process of prophase. nuclear actin played an important role in the process of the chromosome construction
因為cyclinb是有絲分裂前期進程的標志性蛋白,所以我們認為細胞鬆弛素b破壞細胞核內肌動蛋白聚合后,直接影響了有絲分裂前期的進程,進而悅明核內肌動蛋白在有絲分裂前期染色體構建過程中起著重要作用。分享友人
