Background: LAP (TGF-beta 1)

The TGF‑ beta family includes several related proteins (70‑80% sequence homology) from mammalian, avian, or Xenopus systems that are now designated TGF‑ beta 1, TGF‑ beta 2, TGF‑ beta 1.2, TGF‑ beta 3, TGF‑ beta 4, and TGF‑ beta 5. These proteins are secreted by cells in the form of an inactive complex, referred to as latent TGF-beta, that consists of TGF‑ beta associated non-covalently with a Latency-associated peptide (LAP). These two proteins are synthesized as a single pro-peptide that is cleaved in a post Golgi compartment prior to secretion. Different TGF‑ beta family members are naturally associated with their own distinct LAPs.
