Abstract excerpt
The multifunctional cytokine transforming growth factor (TGF) beta1 is secreted in a latent complex with its processed propeptide (latency-associated peptide [LAP]). TGFbeta1 must be functionally released from this complex before it can engage TGFbeta receptors. One mechanism of latent TGFbeta1 activation involves interaction of the integrins alpha v beta6 and alpha v beta8 with an RGD sequence in LAP; other...
