Nim1-related kinases regulate septin organization and cytokinesis by modulating Hof1 at the cell division site
· 2026-09-09 · 原文
The septin scaffold recruits and organizes actomyosin ring (AMR) components; thus, ensuring faithful cytokinesis. The septin-associated kinases – Elm1, Gin4, Hsl1, and Kcc4 are thought to stabilize and regulate the septin architecture at the bud neck, but the underlying mechanisms remain largely unknown. Here, we present a comprehensive, quantitative analysis of these four septin-associated kinases and reveal major roles for Elm1 and Gin4 in septin stability and architectural transitions during the cell cycle. We find that Elm1 and Gin4 play a previously overlooked role in AMR organization and constriction during cytokinesis. We report that the Gin4 kinase interacts directly with the AMR component and F-BAR protein Hof1 via its C-terminal membrane-binding kinase associated-1 (KA1) domain,
