Which protein is responsible for 'severing' actin filaments to promote cytoplasmic fluidity?
Show answer and explanation
Correct answer: Gelsolin
Gelsolin is an actin-binding protein that severs F-actin filaments in a calcium-dependent manner. By breaking the filaments, it caps the newly formed plus ends and helps transition the cytoplasm from a gel state to a sol state.
