|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. CATALYTIC ACTIVITY: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. ENZYME REGULATION: Present in an inactive state in the absence of collagen binding and phosphorylation by SRC. Tyrosine phosphorylation enhances the affinity for ATP and the catalytic activity. 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. TISSUE SPECIFICITY: Detected in osteocytes, osteoblastic cells in subchondral bone, bone lining cells, tibia and cartilage (at protein level). Detected at high levels in heart and lung, and at low levels in brain, placenta, liver, skeletal muscle, pancreas, and kidney. INDUCTION: Up-regulated during osteoblast differentiation (in vitro). Up-regulated in cartilage from osteoarthritis patients. DISEASE: Spondyloepimetaphyseal dysplasia short limb-hand type (SEMD-SL) OMIM: 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. Note=The disease is caused by mutations affecting the gene represented in this entry.|
