![]() | ![]() タイトル: Capture, mutual inhibition and release mechanism for aPKC-Par6 and its multisite polarity substrate Lgl. 著者: Christopher P Earl / Mathias Cobbaut / André Barros-Carvalho / Marina E Ivanova / David C Briggs / Eurico Morais-de-Sá / Peter J Parker / Neil Q McDonald / ![]() ![]() 要旨: The mutually antagonistic relationship of atypical protein kinase C (aPKC) and partitioning-defective protein 6 (Par6) with the substrate lethal (2) giant larvae (Lgl) is essential for regulating ...The mutually antagonistic relationship of atypical protein kinase C (aPKC) and partitioning-defective protein 6 (Par6) with the substrate lethal (2) giant larvae (Lgl) is essential for regulating polarity across many cell types. Although aPKC-Par6 phosphorylates Lgl at three serine sites to exclude it from the apical domain, aPKC-Par6 and Lgl paradoxically form a stable kinase-substrate complex, with conflicting roles proposed for Par6. We report the structure of human aPKCι-Par6α bound to full-length Llgl1, captured through an aPKCι docking site and a Par6 contact. This complex traps a phospho-S663 Llgl1 intermediate bridging between aPKC and Par6, impeding phosphorylation progression. Thus, aPKCι is effectively inhibited by Llgl1 while Llgl1 is captured by aPKCι-Par6. Mutational disruption of the Lgl-aPKC interaction impedes complex assembly and Lgl phosphorylation, whereas disrupting the Lgl-Par6 contact promotes complex dissociation and Lgl phosphorylation. We demonstrate a Par6-regulated substrate capture-and-release model requiring binding by active Cdc42 and the apical partner Crumbs to drive complex disassembly. Our results suggest a mechanism for mutual regulation and spatial control of aPKC-Par6 and Lgl activities. | ||||||||||||
