微丝( f - actin )是由肌动蛋白单体( g - actin )聚合形成的,它参与了真核细胞中复杂的细胞骨架网状蛋白体系的形成。 - Talin is a important f - actin binding protein , two functions of intact talin are the control of actin filament length and the cross - linking of actin polymers . the binding of f - actin to talin significantly increases actin filament stiffness
Talin是一个重要的f - actin结合蛋白,它可以控制微丝的长度,并且同actin聚合体发生交联, f - actin和talin发生的结合可以显著地增加微丝骨架的强度。 - In this study , in order to examine the dynamics of tip [ ca2 + ] i together with the dynamics of tip - localized f - actin in vivo , a kind of double labeled material was constructed . the ca2 + and actin microfilaments of arabidopsis pollen tubes were labeled by cameleon and gfp - mtalin respectively
本研究以拟南芥花粉管为材料,通过转基因技术,将分别标记ca ~ ( 2 + )和微丝的两种荧光蛋白cameleon与gfp - mtalin在花粉管中同时表达,实现活体花粉管中ca ~ ( 2 + )与微丝的同时标记。 - The his - tagged peacl - gfp purified from the supernatants could polymerize into green fluorescent filamentous structures with diameter , length and shape being identical to that of muscle f - actins , which could be labeled by tritc - phalloidin ( a specific agent for staining actin microfilaments ) , and were identified as having a 9 nm diameter by negative staining , corresponding with that of the muscle f - actins ( 7 - 10 nm ) . under polymerization conditions , his - tagged peacl - gfp polymerized with kinetics similar to those of skeleton muscle actin , that is , an obvious lag nucleation period at the beginning of polymerization and an s - like typical polymerization curve could be obtained . the critical concentration is 0 . 75 umol / l near to that of chicken muscle actin ( 0 . 56 umol / l ) under the same condition
荧光标记结合荧光显微观察表明:从可溶性上清中纯化的his - taggedpeac1 - gfp聚合形成的微丝不仅可以直接在荧光显微镜下观察,也可被微丝的特异标记物鬼笔环肽所标记,而且其直径、长度以及形态上与已知的聚合肌动蛋白荧光丝一致;电镜负染的结果进一步证实其直径为9nm ,与传统微丝直径相当( 7 ? 10nm ) ;聚合曲线有明显的停滞期,为典型的s型聚合曲线,聚合临界浓度为0 . 75 mol l ,这一结果与已有报道相似。
