Background: LAP (TGF-beta 1)

The TGF-beta family includes several related proteins (70 - 80% sequence homology) from mammalian, avain 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 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.
