About Thymosin Beta-4

Sequesters G-actin monomers via its WH2 domain, regulating actin dynamics and cell migration. Upregulates metalloproteinases and growth factors for tissue remodeling. Promotes cardiomyocyte survival and angiogenesis post-injury.

The full-length 43-amino acid thymosin beta-4 protein — the parent molecule from which TB-500 (fragment 17-23) and Ac-SDKP (N-terminal cleavage product) are derived. Involved in actin sequestration, wound healing, cardiac repair, and hair follicle activation.
