Question: what are the other 2 protines?

So your cytoskeleton is composed of 3 different proteins – actin, intermediate filaments and microtubules. Actin is the most highly expressed and is the one I’m the most interested in – they all work together to keep the cell stable and supported, but help it perform other functions such as endo / exocytosis – which help it take in different proteins it needs 🙂
