Function:
Tyrosine kinase that functions as cell surface receptor for fibrillar collagen and regulates cell differentiation, remodeling of the extracellular matrix, cell migration and cell proliferation. Required for normal bone development. Regulates osteoblast differentiation and chondrocyte maturation via a signaling pathway that involves MAP kinases and leads to the activation of the transcription factor RUNX2. Regulates remodeling of the extracellular matrix by up-regulation of the collagenases MMP1, MMP2 and MMP13, and thereby facilitates cell migration and tumor cell invasion. Promotes fibroblast migration and proliferation, and thereby contributes to cutaneous wound healing.
Subunit:
Binds hydroxyproline-rich sequence motifs in fibrillar, glycosylated collagen, such as the GQOGVMGFO motif, where O stands for hydroxyproline. Interacts with SRC. Interacts (tyrosine phosphorylated) with SHC1.
Subcellular Location:
Cell membrane; Single-pass type I membrane protein.
Tissue Specificity:
Detected in osteocytes, osteoblastic cells in subchondral bone, bone lining cells, tibia and cartilage. Detected at high levels in heart and lung, and at low levels in brain, placenta, liver, skeletal muscle, pancreas, and kidney.
Post-translational modifications:
N-glycosylated.
Tyrosine phosphorylated in response to collagen binding. Phosphorylated by SRC; this is required for activation and subsequent autophosphorylation on additional tyrosine residues.
DISEASE:
Defects in DDR2 are the cause of spondyloepimetaphyseal dysplasia short limb-hand type (SEMD-SL) [MIM:271665]. A bone disease characterized by short-limbed dwarfism, a narrow chest with pectus excavatum, brachydactyly in the hands and feet, a characteristic craniofacial appearance and premature calcifications. The radiological findings are distinctive and comprise short long bones throughout the skeleton with striking epiphyses that are stippled, flattened and fragmented and flared, irregular metaphyses. Platyspondyly in the spine with wide intervertebral spaces is observed and some vertebral bodies are pear-shaped with central humps, anterior protrusions and posterior scalloping.
Similarity:
Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
Contains 1 F5/8 type C domain.
Contains 1 protein kinase domain.
