Whole mount in situ hybridization showed that amphihmgb transcripts were present ubiquitously in the early embryos from zygote to neurula, but they decreased gradually in mesoderm and endoderm and neural tube with development, and became restricted to epidermal cells in the hatched larva. it appear s that hmgb plays a role in the mitosis and differentiation of embryonic cells. another amphioxus cdna, amphiubf80, encoding ubiquitin / ribosomal fused protein s27a, was isolated from the gut cdna library of b. belcheri tsingtauense
S004cdna序列編碼一個156個氨基酸殘基組成的蛋白質，與人的泛素蛋白ubf80具有較高的氨基酸序列同源性（ 145 / 156同源） ，且該蛋白具有泛素蛋白ubf80所共有的兩個結構域，即由72個氨基酸組成的泛素介導的蛋白降解結構域和由48個氨基酸組成的核糖體蛋白s27a結構域。 -
The exportation resistance of a device work device with what link after loading the resistance s the certain connections for should satisfying, in order to prevent mount to load the appearance produce the obvious influence. with each other connect to say to electronics equipments, for example after signal connect the enlarger, ex - class to connect class, only behind first - degree importation resistance before larger than first - degree exportation resistance 5 - 10 times are above, can think the resistance to match good ; connect the box come saying, electronics tube the machine should choose to use with for the enlarger its output to carry the mark to call the resistance the box for, but transistor enlarger then have noing this restrict, can take officing why resistance of equal or approximate box
一件器材的輸出阻抗和所連接的負載阻抗之間所應滿足的某種關系，以免接上負載后對器材本身的工作狀態產生明顯的影響。對電子設備互連來說，例如信號源連放大器，前級連后級，只要后一級的輸入阻抗大於前一級的輸出阻抗5 - 10倍以上，就可認為阻抗匹配良好對于放大器連接音箱來說，電子管機應選用與其輸出端標稱阻抗相等或接近的音箱，而晶體管放大器則無此限制，可以接任何阻抗的音箱。
