TB-500 5 mg

Description

TB-500, or Thymosin Beta-4, is a synthetic analog of the endogenous Thymosin beta 4 protein, which is considered ubiquitously present in cells. The peptide belongs to a widespread family of 16 related molecules considered to exhibit a high degree of sequence conservation and localization in the majority of tissues and circulating cells.

Thymosin Beta-4 is speculated to encompass a unique peptide sequence, LKKTETQ, found between the 16th and 24th amino acids. This sequence is thought to assist in actin binding potentially. Actins are proteins believed to be vital to the cell’s cytoskeleton. They appear to maintain the cell’s structural framework and are considered by experts to be crucial for primary cellular activities, such as movement.

It is hypothesized that Thymosin Beta-4 associates with actin by attaching to globular actin (G-actin), the monomeric form of actin, before it forms filamentous actin (F-actin). This suggested interaction between Thymosin Beta-4 and G-actin might impede the polymerization process, a mechanism known as actin sequestration. This interference might potentially increase the concentration of G-actin.
