ROR2 (receptor tyrosine kinase-like orphan receptor 2), also known as NTRKR2 (neurotrophic tyrosine kinase, receptor-related 2), is a single-pass type I transmembrane glycoprotein that belongs to the ROR subfamily of the tyrosine protein kinase family. The ROR subfamily members, ROR1 and ROR2, are tyrosine kinase receptors important in regulating skeletal and neuronal development, cell migration and cell polarity. Each ROR member contains 1 FZ (frizzled) domain, 1 Ig (immunoglobulin)-like C2-type domain, and 1 kringle domain in the extracellular region and 1 protein kinase domain in the cytoplasmic region. ROR2 is expressed at high levels during early embryonic development. The expression levels drop strongly around day 16 and there are only very low levels in adult tissues.  ROR2 may be involved in the early formation of the chondrocytes and required for cartilage and growth plate development. ROR2 exists as a homodimer on the cell surface and may mediate a signaling pathway that promotes osteogenesis and bone formation. Mutations in the ROR2 gene can cause brachydactyly type B, a skeletal disorder characterized by hypoplasia/aplasia of distal phalanges and nails. In addition, mutations in this gene can cause the autosomal recessive form of Robinow syndrome, which is characterized by skeletal dysplasia with generalized limb bone shortening, segmental defects of the spine, brachydactyly, and a dysmorphic facial appearance. ROR2 appears to possess dual roles as a tumor suppressor or activator depending on tumor type.
