Ana1/Cep295 regulates centriole elongation via Cep135 and microtubules.

Ana1/Cep295 promotes centriole elongation in fly spermatocytes through interactions with Cep135 and microtubules, leading to overelongation.

• Why it matters: Understanding how centrioles elongate is crucial because they are vital for centrosome and cilium formation, yet the mechanisms behind their length regulation are not fully known.
• What they did: Researchers investigated Ana1/Cep295's role by examining its interactions with Cep135 and microtubules, demonstrating that Ana1 directly promotes elongation via these two mechanisms.
• The result: Both interactions contribute to centriole overelongation, revealing that Ana1 coordinates multiple pathways to regulate centriole length during spermatogenesis.
