Introduction

Ciliary neutrophic factor (CNTF) is a nerve growth factor belonging to the interleukin-6 family of neuropoietic cytokines. Other members of this family include leukaemie inhibitory factor (LIF), IL-6, IL-11 and oncostatin M (Wang 2012).

Structure

Overview

CNTF is a roughly 22.7 kDa protein consisting of a single polypeptide chain of 200 amino acid residues. Like with many other cytokines, the tertiary structure of CNTF consists of four anti-parallel α-helices (A-D), where helices A-B and C-D are connected by two cross-over loops and helices B-C by one short loop.
