  1. Our previous studies showed existence of apoplast cam in the plant cell and cam had many extracellular functions. so it supposed cam may be one of important extracellular polypeptides and trigger the intracellular signal transduction by binding the receptor. in this study, radiolabelled ligand is used to investigate the binding characteristic of cam and a. thaliana protoplasts. and chemical crosslinking is employed to explore binding proteins in the membrane. at first, ( 35 ) ~ s - cam was produced using ( 35 ) ~ s - labeled amino acid mixture in e. coli. sds - page and autoradiograph indicated high - purified, high - specific radioactivity ( 35 ) ~ s - cam was obtained. electrophoresis of ( 35 ) ~ s - cam is the same as that of unlabeled cam with ca ~ ( 2 + ) or egta ; a quatitive of protoplasts was prepared by enzymolysis

    首先，用~ （ 35 ） s標記的氨基酸混合物喂養工程菌成功地制備了~ （ 35 ） s標記的擬南芥鈣調素（ ~ （ 35 ） s - cam ） ， ~ （ 35 ） s - cam純度高、放射活度高、 ca ~ （ 2 + ）與egta存在時的電泳行為與未標記cam相同，可作為一種高靈敏性的探針用於進行受體學分析實驗；用擬南芥種子誘導愈傷，通過酶解制備了大量原生質體。
  2. It was important glucoprotein modulating cell functions by combination to idiosyncrasy receptor on cell membrane, which inducing process of cascade signal magnifying, then passing signals into nucleus to induce the modulation of the serial gene expression and viarous physiological reaction, and inhence immunity and antivirus

    人-干擾素（ hu - - ifn ）是人體因病毒感染或其它誘生劑作用等所產生的一類非特異性抗病毒物質，是調節細胞功能的一類重要的糖蛋白。
  3. Plant defensin disrupts the cell membrane of phytopathogen differently from cema that contacts directly with the cell membrane. plant defensins are thought to interact with specific receptor harboring in the cell membrane

    由於對真菌，特別是絲狀真菌有很強的抑制作用，而對植物細胞沒有毒害作用，防禦素有望在植物抗病基因工程中得到廣泛應用。
  4. Rubber tree ( hevea brasiliensis ) is an important economic woody - crop in tropical areas. its latex is the unique source of crude rubber used in current industry. because of its special and important use, the rubber tree has been extensively planted in tropical areas. increase production is always the main target in rubber tree cultivation. since the ethrel was applied in increasing latex production in 1968 for the first time as a chemical stimulant, not only the latex production had been increased largely, but also a new set of rubber tapping system had been established, leading to a series of economic benefit. owing to ethrel " s extensive application, its side effects had been found more and more obviously, such as tapping dry, speeding up senescence, shortening the life span of rubber tree etc. in order to overcome the side effects and increase production more availably, for a long time, people had carried out lots of research work on cell level, membrane level, physiology and biochemistry of laticifer contents. but the mech anism why ethrel increased latex production was not yet understood completely. this study had cloned the ethylene receptor gene ( efrl ) from rubber tree, and researched the relationship between etrl expression in laticifers and ethrel stimulation on transcription level and protein translation level. the results were as follows : 1

    但是，由於乙烯利應用的普及，乙烯利刺激割膠引起橡膠樹發生死皮病及加速膠樹衰老，縮短膠樹壽命等副作用也越來越明顯。為了克服這些副作用，使乙烯利能更有效地刺激增產，長期以來，人們在細胞水平、膜水平和乳管細胞內含物的生理生化層面上進行了大量的研究，但仍未完全了解乙烯對膠樹的作用機制。本研究從分子水平入手，克隆橡膠樹的乙烯受體基因（ etr1 ） ，並在轉錄水平和蛋白質翻譯水平上研究etr1基因在乳管細胞中的表達及與乙烯刺激的關系，取得了以下結果： 1
  5. Resent studies demonstrate that, such as gabaar1 subunit of gaba receptor, ka2 and glur6 subunit of ka receptor, there are some functional regions in that of c terminus which can regulate these subunits targeting to the cell membrane surface. while little was known whether nmda receptor ' s nr2b subunit has the similar domains

    最近有一些研究報道，許多突觸受體如gaba （ b ）受體rl亞單位、 ka受體的kaz和glur6亞單位以及孤兒受體腿亞單位的胞內區，存在有影響受體運輸到細胞膜的功能區，但是尚未有對于nmda受體的nrz亞單位膜運輸的報道。
  6. A single molecule of rta is able to depurinate 1500 - 2000 ribosomes per minute. ricin b chain ( rtb ) is a galactose - specific lectin which binds to the receptors on cell surfaces, and may enhance rta translocation by forming a pore in the membrane of intracellular organelles. ricin enters the cells by receptor - mediated endocytosis

    內吞進入細胞的蓖麻毒素一部分返回到膜表面，一部分經早期內體至晚期內體，最後在溶酶體中降解，只有一小部分約5到達高爾基體，隨后逆轉運到粗面內質網，在那裡rta才和rtb解離，游離出有催化活性的rta 。
