The spindle-associated antisense RNA ARHGEF17-AS1 functionally contributes to mitotic spindle integrity.
- Open access
ARHGEF17-AS1 is essential for mitotic spindle integrity, regulating spindle organization through interactions with RPS3, dynein, and RNF10 during mitosis.
- Why it matters: Understanding how long non-coding RNAs influence mitotic progression is crucial, as few have been shown to directly affect the mitotic spindle, impacting cell division fidelity.
- What they did: The study identified ARHGEF17-AS1 as a metaphase-enriched antisense RNA that localizes to the spindle, interacts with RPS3 and dynein, and influences RPS3 recruitment and ubiquitination at spindle poles, using molecular interaction analyses and depletion experiments.
- The result: Depleting ARHGEF17-AS1 disrupts spindle microtubule organization, delays mitosis, and reduces RPS3 and RNF10 levels, highlighting its key role in maintaining proper spindle structure and progression.
