当Wolynes注意到,两种广泛使用的细胞生物学教材对于跨膜蛋白如何折叠有*不同的意见时,受到启发研究膜蛋白。他说:“其中一本教材,列出所有规则,说:‘这是证据表明,它是动力学控制的。’另外一本教材指出:‘这是证据表明,它是热力学控制的。’它们以那种方式被写入教材,好像是确定。我想说我仍然不确定,但我认为我们的工作更多地指出,折叠是热力学(平衡)控制的,至少一次蛋白质是停留在膜中。”
Kim和Schafer修改了Wolynes实验室使用的一种蛋白质折叠算法,被称为联想记忆、水介导的结构和能量模型(AWSEM),来解释膜蛋白所*的外界影响,包括将部分折叠蛋白质插入膜的易位子机制和膜本身。
利用这种算法,他们成功地确定,热力学漏斗在膜蛋白折叠中似乎仍然占据上风,如同它们为球状蛋白质所做的。
Kim称:“我们有来自许多不同实验室的膜蛋白结构数据库,我们能了解在它们之间转换的参数。这些参数两个残基(珠)应该相互作用的多么强烈,并考虑周围的环境。这可让我们能够从原始序列做出预测。”
随着越来越多的结构变得可用,研究人员希望调整AWSEM膜算法。Wolynes说:“我不认为我们已经了解膜的相互作用。”这表明大部分的漏斗形折叠发生在蛋白质进入膜之后,很少是因为疏水性(动力学)相互作用,疏水性相互作用在球状蛋白质折叠中发挥了更大的作用。他说:“我的直觉是,那将是正确的。”
Wolynes说:“本文的意义在于,现在我们有一种运算法则,可根据原始的基因组序列,相当好地预测膜蛋白结构。这对于解释新一代的实验结果将非常的有用。”
从受精卵到成年人,人类细胞需要经历的分裂次数可以说是天文数字。每一次分裂时,母细胞都必须将DNA精确分配给两个子细胞。而着丝粒的完整性是细胞成功分裂的关键。着丝粒是染色体上的一个特殊DNA区域,是纺锤丝微管的附着之处,也是姐妹染色单体在分开前相互连接的地方。分离染色体的微管要识别着丝粒,需要该区域富含一种关键的蛋白——CENP-A。在细胞进行DNA复制准备分裂的时候,需要确保新旧DNA链的着丝粒区域填充有足够的CENP-A。在此之前人们只知道着丝粒在G1期填充CENP-A,但并不了解这一过程的具体调控机制。

Wolynes was inspired to study membrane proteins when he noted that the two widely used textbooks on cell biology have compley different opinions about how the transmembrane proteins fold. He said: "One of the textbooks lists all the rules, saying: 'This is evidence that it is kinetically controlled.'" Another textbook states: 'This is evidence that it is thermodynamically controlled.' ' It seems to be absoluy certain that the text was written in that way, and I would like to say that I am still not sure, but I think our work more often states that the folding is thermodynamically (equilibrium) controlled, at least once the protein is stuck in the film "
Kim and Schafer modified a protein folding algorithm used by Wolynes Lab called associative memory, water-mediated structure and energy model (AWSEM) to account for the external effects unique to membrane proteins, including the insertion of partially folded proteins Membrane translocation mechanism and membrane itself.
Using this algorithm, they succeeded in determining that the thermodynamic funnels still seem to hold the upper hand in membrane protein folding as they do for globular proteins.
"We have a database of membrane protein structures from many different laboratories and we know the parameters that switch between them." These parameters specify how strongly two residues (beads) should interact and take into account the surrounding environment This allows us to make predictions from the original sequence. "
As more and more structures become available, researchers hope to adapt the AWSEM membrane algorithm. Wolynes said: "I do not think we have understood the membrane interactions." This shows that most of the funnel-shaped folds occur after the proteins enter the membrane, seldom because of hydrophobic (kinetic) interactions, hydrophobic interactions in the globular Protein folding has played a greater role. He said: "My intuition is that it will be right."
Wolynes says: "What this article means is that now we have an algorithm that fairly predicts the membrane protein structure based on the original genome sequence, which is very useful to explain the new generation of experiments."
From fertilized eggs to adults, the number of divisions human cells need to go through can be said to be astronomical. Each division, the mother cell must be precisely allocated to two daughter cells. The integrity of the centromere is the key to successful cell division. Centromeres are a special DNA region on chromosomes, where spindle microtubules attach themselves and where sister chromatids are connected before they are separated. Microtubules that separate chromosomes recognize centromeres and require this region to be enriched with a key protein, CENP-A. When the cell is ready for DNA replication, it is necessary to ensure that the centromeric regions of the new and old DNA strands are filled with sufficient CENP-A. Before that, people only knew that centromere filled CENP-A in G1 phase, but did not understand the specific regulation mechanism of this process.
