What the molecule is, where the sequence comes from, and what it binds. This page does not describe what TB-500 does.
Structure
What TB-500 is
Origin. A synthetic fragment of thymosin beta-4, a naturally occurring 43-residue protein.
Molecular target. The parent protein is an actin-sequestering protein; the fragment carries the actin-binding motif.
Both statements are facts about the molecule and can be checked against any reference database. Neither is a statement about an outcome, and this page makes none.

Grouped by structure
Signalling peptides
Short sequences that bind a receptor or a partner protein. Grouped by what the molecule is and what it binds, not by what anyone intends to do with it.
Compounds on this site are grouped by what the molecule is, not by what anyone intends to do with it. TB-500 sits with 10 other compounds in this group because of its structure and its target, and for no other reason.
Compared side by side: TB-500 vs Thymosin Alpha-1 and Semax vs TB-500.
