Background Information

Patients with paraneoplastic cerebellar degeneration (PCD) carry a characteristic antibody called anti-Yo. On Western blot analysis of Purkinje cells and tumor tissue from CD patient, the anti-Yo sera react with at least 2 antigens, a major species of 62 kD called CDR62 or CDR2 [PMID:18045792]. CDR2 is partly characterized, as CDR2 through its leucine zipper motif has been demonstrated to interact with c-myc, with cell cycle-related proteins and with a protein kinase, indicating that CDR2 is involved in signal transduction and gene transcription. Furthermore, CDR2 has been found to attenuate hypoxic response in renal cell carcinoma, and recent data suggest a role for CDR2 and c-myc in mitosis in cycling cells [PMID:21080165].
