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. {ECO:0000269PubMed:11375938, ECO:0000269PubMed:11723120, ECO:0000269PubMed:11884411, ECO:0000269PubMed:15509586, ECO:0000269PubMed:19681157}.

Subcellular Localization

Cell membrane; Single-pass type I membrane protein.

Disease Associations

Note=Defects in Ddr2 are the cause of the smallie (sli) phenotype. Smallie mice show distinct dwarfing, with reduced body mass and reduced bone mineral content. Mice also have mild craniofacial deformities, such as protuberant eyes and snub noses. Smallie mice have a reduced life span, with about half of them dying within 6 months. Matings between male and female smallie mice do not yield any offspring. The levels of circulating steroid hormones remain at a level corresponding to prepubertal wild-type mice. Adult testes exhibit much reduced numbers of spermatids with atrophy of spermatogonia, Sertoli and Leydig cells. Ovaries show an absence of corpora lutea.

Tissue Specificity

Widely expressed. Detected in lung, ovary, skin and in testis Leydig cells (at protein level). Widely expressed. Detected at high levels in heart, lung, skeletal muscle, central nervous system (CNS) and kidney, and at lower levels in brain and testis. Detected in chondrocytes in tibia growth plates of young mice. {ECO:0000269PubMed:11375938, ECO:0000269PubMed:18483174, ECO:0000269PubMed:19681157}.
