GARP (LRRC32) is a transmembrane protein that binds latent-TGF-β1 and tethers it on the Treg surface.
and has been proved to promote the activation and secretion of transforming growth factor β (TGF-β).
The expression of GARP is highly on the surface activated Tregs and increases the suppressive function of Tregs.
Additionally, GARP can bind to latent transforming growth factor β (TGF-β), thus promoting secretion and activation of TGF-β.
TGF-β plays a critical rule for homeostasis and function of Tregs.
Notably, it has been also observed that fibroblasts and endothelial cell lines that express GARP/latent TGF-β1 complexes do not activate TGF-β1.
However, it cannot be excluded that specific stimuli are required to trigger TGF-β1 activation from complexes on the surface of these cell types.
特徴
Human LRRC32&TGFB1 Heterotrimer protein, His Tag&Tag Free (the molar ratio of LRRC32 & TGF-beta 1 equals 1:2) is produced by co-expression of LRRC32 and TGF-beta 1, which has a calculated MW of 68.0 kDa (LRRC32), 28.5 (LAP) and 14.8 kDa (mature TGF-beta 1) respectively.
LRRC32 is fused with a polyhistidine tag at the C-terminus and TGF-beta 1 contains no tag.
The reducing (R) Heterotrimer protein migrates as 70 kDa (LRRC32), 38-45 kDa (LAP) and 14 kDa (mature TGF-beta 1) due to glycosylation respectively.
