[2025-10-01T16:30:24.051334] [PI reasoning] **Identifying intermediate filaments**

I need to clarify that vimentin, keratin, and desmin are indeed intermediate filament proteins. Tubulin, on the other hand, is a microtubule protein made of dimers. The question asks which of these isn't a monomeric intermediate filament. So, my answer is tubulin. I could include citations to support this, and it might be useful to search for articles about the distinction between tubulin and intermediate filaments. This seems like a straightforward inquiry!
