Cytoskeleton
Cytoskeleton — The internal framework of protein filaments and tubules that gives cells their shape and enables movement, reorganized by actin-binding peptides like thymosin beta-4.
What Is the Cytoskeleton?
The cytoskeleton is the network of protein filaments (actin, microtubules, intermediate filaments) that provides cell structure, enables motility, and drives intracellular transport. TB-500 (Thymosin Beta-4) promotes wound healing by sequestering G-actin and promoting actin polymerization, directly linking peptide biology to cytoskeletal dynamics.
Peptide Context
- TB-500: Binds G-actin, promoting F-actin polymerization for cell migration and wound closure
- Phalloidin: Cyclic peptide toxin from Amanita mushrooms. Binds and stabilizes F-actin. Used as actin stain
- Jasplakinolide: Cyclic depsipeptide that stabilizes actin filaments and induces actin polymerization
Frequently Asked Questions
