TGFb_propeptide

TGFb_propeptide
PFAM accession number:PF00688
Interpro abstract (IPR001111):

TGF-beta is secreted as a latent complex, consisting of the TGF-beta dimer non-covalently bound to LAP (latency associated peptide) plus a latent TGF-beta binding protein (LTBP). After post-translational processing, TGF-beta binds non-covalently to LAP, a homodimer formed from the propeptide region of TGF-beta, to confer latency [(PUBMED:9150447)]. Latent TGF-beta can then be targeted to the extracellular matrix (ECM) by LTBP. The LAP dimer is usually disulfide-bound to LTBP [(PUBMED:15611103)].

This entry represents the propeptide region of TGF-beta that forms LAP.

This is a PFAM domain. For full annotation and more information, please see the PFAM entry TGFb_propeptide
