概括

我们开发了一个高通量蛋白质组学平台,以发现新的分子降解剂 (MGD). 这个平台为MGDs确定了新的蛋白质标,扩大了超越传统药物标的治疗可能性.

科学领域:

蛋白质组学是指蛋白质组学.
药物发现药物发现药物发现
分子生物学分子生物学

背景情况:

分子粘合剂降解剂 (MGDs) 劫持了针对蛋白质降解的无处不在蛋白质蛋白质系统,为无法使用的目标提供了潜在的潜力.
由于缺乏合理的设计和低通量查方法,发现新型MGDs受到阻碍.

研究的目的:

开发一个高通量蛋白质组学平台,以高效地发现MGD.
通过不偏的查来识别新型MGD及其蛋白质基质 (新基质).

主要方法:

使用了一个无标签,数据独立的获取质谱 (DIA-MS) 平台,用于集成蛋白质组学和无处不在的蛋白质组学.
选了100个大脑细胞 (CRBN) 招募配体.
根据全球蛋白质组学指导,进行结构降解关系分析.

主要成果:

确定了广泛的新型MGD和以前未被描述的新基质.
发现了强效和选择性的基于基利胺的降解剂,针对KDM4B,G3BP2和VCL.
发现这些新基质没有经典的CRBNβ-hairpin降解.

结论:

公正的高通量蛋白质组学是MGD药物发现的强大方法.
CRBN新基质的景观比以前由经典免疫调节药物 (IMiDs) 定义的要大得多.

Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...
