Gq protein is a type of heterotrimeric g protein which is made up of, . gq protein which have been discovered recently exist in many invertebrate photoreceptor cells
Gq蛋白是最近幾年發現的存在於許多無脊椎動物的感光細胞內的一種g蛋白類型，是由、 、三個亞基組成。 -
Our previous work verified that heterotrimeric g protein was involved in regulation of pollen germination, tube growth and in the transmembrane mechanism of extracellular cam signal. in the present study, we provide further evidence that plc signaling pathway was presented in lily pollen and involved in extracellular cam signal transduction mechanism in pollen by molecular, biochemical and physiological approaches. these evidence included : the pip _ ( 2 ) - dependent plc activity was also detected in purified lily pollen protoplasts
為了給上述信號轉導過程提供進一步的證據，本文以百合花粉為材料，從plc活性的測定、 plc基因的克隆及其與花粉萌發的關系、以及plc活性被g蛋白和cam調控等方面，為肌醇磷脂系統參與花粉萌發和細胞外鈣調素的信號轉導過程進一步提供了分子生物學和生物化學的證據。 -
It was found that plc activity was stimulated by both exogenous purified calmodulin and heterotrimeric g protein agonist cholera toxin. while, the stimulated effect on plc activity caused by exogenous calmodulin was inhibited by heterotrimeric g protein antagonist pertussis toxin, and plc antagonist u - 73122 inhibited the effect caused by cholera toxin. we also measure the free ca ~ ( 2 + ) level in germinating pollen grains, and found that exogenous purified calmodulin was able to increase the free ca ~ ( 2 + ) level, and their effects on ca ~ ( 2 + ) level were inhibited by u - 73122
實驗中，利用[ ~ 3h ] pip _ 2和花粉原生質體共同孵育的體系，檢測出了百合花粉細胞具有依賴pip _ 2的plc活性；利用該體系還檢測出外源鈣調素可促進plc的活性，其中10 ~ （ - 9 ） m的鈣調素可使plc的活性提高三倍；異三聚體g蛋白的激活劑ctx可以激活plc的活性，而其抑制劑ptx可明顯抑制plc活性；外源鈣調素的這種作用可以被ptx抑制；而plc抑制劑u - 73122抑制ctx對plc的激活效應。 -
Recent researches implicate that raplgap may interact with different type of alpha subunit in heterotrimeric g protein and suggest a cellular cross - talk between small g proteins and heterotrimeric g protein
最近研究發現，某些g亞單位可與rap1gap結合而調節rap1gap的活性或影響異源三聚體g蛋白的信號轉導。 -
All of above main results suggested that ga was involved in pollen germination and tube grown by regulating cytosilic free calcium level, whereas gp was not, and extracellular cam might regulate pollen germination and tube growth through ga. the heterotrimeric g proteins had participated in several other development processes in arabidopsis
從野生型和突變體花粉細胞中游離鈣離子水平對外源鈣調素的反應能力看， g蛋白參與了花粉萌發過程中外源鈣調素的跨膜信號轉導，且進一步通過其下游的鈣信使來調控。 -
Northern blot and rt - pcr analysis verified that the expression level of ldplcl was induced in germinating pollen, whereas ldplc2 expression level did not change during pollen germinating process. the interaction between heterotrimeric g proteins and plc was detected in a yeast two - hybrid system
Northern和rt - pcr分析，發現隨著花粉的萌發， ldplc2的轉錄活性提高，而ldplc1博士學位論文在萌發前後的轉錄水平沒有變化，推測至少ldplcz參與了對花粉萌發的調控。
