背景信息

Cerebellar degeneration-related protein 2-like (CDR2L) is a neuronal protein primarily expressed in the cerebellum, sharing structural and functional similarities with CDR2. a well-characterized antigen in paraneoplastic neurological disorders. CDR2L contains conserved domains, including zinc finger motifs, suggesting potential roles in RNA binding or transcriptional regulation. It has garnered attention due to its association with autoimmune cerebellar degeneration, particularly in paraneoplastic syndromes where cross-reactive immune responses target cerebellar neurons.

In such cases, malignancies (e.g., breast or ovarian cancers) trigger autoantibodies against tumor antigens that molecularly mimic CDR2L, leading to cerebellar dysfunction. Recombinant CDR2L is widely used in research and diagnostics to detect these autoantibodies, aiding in the diagnosis of paraneoplastic cerebellar degeneration. Despite this, the precise physiological function of CDR2L remains unclear. Studies suggest it may contribute to cerebellar development or synaptic plasticity, though knockout models show no overt phenotypes, hinting at functional redundancy with related proteins.

Current research focuses on clarifying its pathological role in autoimmune-mediated damage and exploring therapeutic strategies to block harmful immune responses without compromising tumor surveillance. The protein’s dual relevance to neurology and oncology underscores its clinical and scientific significance.
