Intermediate filaments, role in support

Written by Cindy Ma on Feb 13, 2020

Intermediate filaments are protein fibers that contribute to cellular structural and are often crucial in holding together tissues.

Intermediate filaments are part of the cytoskeleton found in animal cells are composed of a family of related proteins sharing common structural and sequence features. Intermediate filaments contribute to cellular structural elements and are often crucial in holding together tissues like skin. One protein that forms intermediate filaments is keratin, a fibrous protein found in hair, nails, and skin.

They play no role in movement or transport. They also do not form and dissemble quickly. You may think of them as playing the same role as springs in a mattress!

Key Point

  • Intermediate filaments are protein fibers that contribute to cellular structural and are often crucial in holding together tissues.

Key Terms

  • intermediate filaments: protein fibers that contribute to cellular structural elements and are often crucial in holding together tissues
  • cytoskeleton: network of protein fibers that help with cellular movement and maintaining its structure/shape
