摘要：A structural profile-based computational screen was used to identify neuropoietin (NP), a new cytokine. The np gene is localized in tandem with the cardiotrophin-1 gene on mouse chromosome 7. NP shares structural and functional features with ciliary neurotrophic factor (CNTF), cardiotrophin-1, and cardiotrophin-like cytokine. It acts through a membrane receptor complex comprising CNTF receptor-{alpha} component (CNTFR{alpha}), gp130, and leukemia inhibitory factor receptor to activate signal transducer and activator of transcription 3 signaling pathway. NP is highly expressed in embryonic neuroepithelia. Strikingly, CNTFR{alpha
