The CNTFR gene encodes the ciliary neurotrophic factor receptor alpha (CNTFRα), a critical component of the CNTF receptor complex. CNTFRα is essential for signaling by ciliary neurotrophic factor (CNTF) and cardiotrophin-1 (CT-1), which are major neurotrophic factors supporting motor neuron survival and function. This GPI-anchored receptor lacks a transmembrane domain and must associate with signaling receptor subunits (gp130 and LIFR) to mediate intracellular signaling.
The CNTFR gene is located on chromosome 9p13.3 and consists of 10 exons spanning approximately 8 kb of genomic DNA. The gene encodes a protein of 389 amino acids with a molecular weight of approximately 45 kDa.
CNTFR has multiple transcript variants:
CNTFRα contains several functional domains:
CNTFRα forms a tripartite receptor complex:
Upon CNTF binding, the receptor complex activates:
| Pathway | Primary Effect |
|---|---|
| JAK/STAT3 | Gene transcription, survival |
| MAPK/ERK | Differentiation, growth |
| PI3K/Akt | Survival, anti-apoptotic |
| PLCγ | Calcium signaling |
CNTFR is highly expressed in:
| Approach | Status | Target |
|---|---|---|
| CNTF protein | Phase III (ALS) | CNTFR complex |
| AAV-CNTFR | Preclinical | Motor neurons |
| CT-1 mimetics | Discovery | CNTFR/gp130 |
