Target Information

Receptor-tyrosine-kinase-like orphan receptor 1 (ROR1) is a tumor-associated surface protein predominantly expressed during embryogenesis, where it is involved in organ morphogenesis, nervous system development, and neural progenitor cell maintenance and survival. It is virtually absent from normal pediatric and adult tissues except for low-level expression in immature B cell precursors (hematogones) and adipocytes. ROR1 is notably overexpressed in several B lymphoid and epithelial malignancies, including chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), acute lymphoblastic leukemia (ALL), marginal zone lymphoma, and lung adenocarcinoma.

First identified during PCR-based cloning of a human neuroblastoma cell line, ROR1 was classified as an orphan receptor due to its elusive ligand. Wnt-5a has since been suggested as a candidate ligand, and ROR1 functions as a pseudokinase, promoting proliferation and resistance to apoptosis in cancer cells through interaction with Wnt-5a and TCL1-mediated AKT co-activation. ROR1 is expressed as a glycoprotein containing extracellular immunoglobulin (Ig)-like, Frizzled, and Kringle domains, as well as an intracellular tyrosine kinase domain.
