生物学与医学研究中,"gain-of-function"(增强型功能)与"loss-of-function"(丧失型功能)是描述基因或蛋白质变异对生物体影响的术语。Gain-of-function变异导致基因或蛋白质功能增强或出现新功能,可能改变蛋白质表达水平、活性或时间、位置表达。此类变异可引发异常现象,如细胞增殖增加、代谢率提升或信...
Gain-of-function 指的是当一个基因或蛋白质发生变异后,导致其功能增强或出现新的功能。这可能包括增加...
在芒果病毒漫谈系列中,我们专门介绍过一类膜分子——B细胞相关分子是,B7基因家族(漫谈病毒07.B细胞相关分子做生信,从B7基因家族说起)。董晨团队2018年在Immunity发表题为“Co-inhibitory Molecule B7 Superfamily Member 1 Expressed by Tumor-Infifiltrating Myeloid Cells Induces Dysfunction of Anti-tumor CD8+ T C...

损失函数(loss function也叫作cost function)是用来估量你模型的预测值f(x)与真实值Y的不一致程度,它是一个非负实值函数,通常使用L(Y, f(x))来表示,损失函数越小,模型的鲁棒性就越好。损失函数是经验风险函数的核心部分,也是结构风险函数重要组成部分。模型的结构风险函数包括了经验风险项和正则项,通常可以表示...
(Dominance)的主要类别与机制,以及通常与其相关的突变类型。 Loss of function 功能丧失 Haploinsufficiency 单倍剂量不足 单倍剂量不足: 指一个等位基因突变后,另一个等位基因能正常表达,但这只有正常水平50%的蛋白质不足以维持细胞正常的生理功能。 即杂合突变即可产生症状 ...

Fig. 3: Gain-of-function and dominant-negative mutations are milder than loss-of-function mutations. a Comparison of predicted | ΔΔG | values for gnomAD variants and pathogenic ClinVar mutations from AD genes classified as dominant negative (DN), gain of function (GOF) and haploin...
Rice paddies are a major source of methane emissions. To meet the food demand of the growing population and to cope with global warming, reducing greenhouse gases and enhancing yields are critical. Here we demonstrate that a loss-of-function rice allele,gs3, mitigates methane emissions from meth...
