Family of carrier proteins

The latent TGF-beta binding proteins (LTBP) are a family of carrier proteins.

LTBP is a family of secreted multidomain proteins that were originally identified by their association with the latent form of transforming growth factors. They interact with a variety of extracellular matrix proteins and may play a role in the regulation of TGF beta bioavailability.
