Fig. 6: Schemetic model for the specific TGF-β1 signal of the myeloid lineage cells designated by LRRC33 and integrin αVβ8.
From: Specificity of TGF-β1 signal designated by LRRC33 and integrin αVβ8

The three key residues that determine the specific cell-surface L-TGF-β1 presentation by LRRC33 are labeled. The cognate residues of L-TGF-β2 and L-TGF-β3 are also indicated with the major discriminative ones colored in red.
