Synthesis pass · prose summary of the discoveries below

DDR1 is a collagen-activated receptor tyrosine kinase that transduces extracellular matrix signals into diverse cellular responses including adhesion, migration, ECM remodeling, epithelial differentiation, and mechanotransduction. DDR1 exists as disulfide-linked dimers mediated by stalk-region cysteines (Cys303, Cys348); collagen binding to surface loops of the discoidin domain induces lateral association of pre-formed dimers, clustering, and trans-phosphorylation dependent on the transmembrane leucine zipper, followed by dynamin-mediated endocytosis (PMID:16774916, PMID:18065762, PMID:28590245, PMID:19007791). Downstream, DDR1 signals through phosphotyrosine-dependent recruitment of Shp-2 (at Y740), Nck2, and BCR, and activates NF-κB–NRF2, STAT3, Src–FAK, and Hippo–YAP pathways—the latter via liquid–liquid phase separation that sequesters LATS1 from MOB1 (PMID:16337946, PMID:29438985, PMID:36475898, PMID:36198801). The DDR1 extracellular domain independently organizes collagen fiber alignment to exclude T cell infiltration in tumors, while kinase-dependent signaling drives vascular remodeling after injury, kidney fibrosis, and intestinal barrier regulation (PMID:34732895, PMID:11254672, PMID:34941574, PMID:35905891).

2006 DDR1 forms ligand-independent dimers in the biosynthetic pathway and on the cell surface; the transmembrane leucine zipper (but not the GXXXG motif) is required for collagen-induced signaling, as leucine-zipper mutations abolish kinase activation while still permitting dimerization.
