产品介绍
KB02-SLF 是一种基于 PROTAC 的核 FKBP12 降解剂 (molecular glue)。KB02-SLF 通过共价修饰 DCAF16 (E3 ligase) 促进 FKBP12 降解,并可以提高生物系统中蛋白质降解的持久性。KB02-SLF 由 SLF 与泛素 E3 连接酶配体 (KB02) 通过 linker 连接而成。

产品描述

KB02-SLF is a PROTAC-based nuclear FKBP12 degrader (molecular glue). KB02-SLF promotes nuclear FKBP12 degradation by covalently modifying DCAF16 (E3 ligase) and can improve the durability of protein degradation in biological systems. SLF binds ubiquitin E3 ligase ligand KB02 via a linker to form KB02-SLF[1].

KB02-SLF (2 µM; 4-72 hours; HEK293T cells) treatment promotes a substantial reduction in nuclear FKBP12 that is sustained across a 4-72 h time frame[1].Cell imaging studies confirms the selective loss of nuclear-localized FKBP12 in KB02-SLF-treated cells. KB02-SLF promotes the loss of FKBP12_NLS across a concentration of ~0.5-5µM, but shows varied reductions in activity at higher concentrations. The degradation of FKBP12_NLS induced by KB02-SLF is mediated by DCAF16[1].
