Name :
Human CNTFR/CNTFRA Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant
Description :
CNTFR or CNTFRa (Ciliary neurotrophic factor receptor subunit alpha) is a GPI-anchored surface glycoprotein of the type I cytokine receptor family, type 3 subfamily. CNTFR consists of an extracellular region with 1 Ig-like C2-type (immunoglobulin-like) domain, 2 fibronectin type III (FN3) domains and a juxtamembrane WSXWS motif, in addition to a transmembrane (TM) domain, and a cytoplasmic tail. The WSXWS motif is necessary for proper protein folding and efficient intracellular transport and cell-surface receptor binding. CNTF is one of the cytokines including IL6, LIF, OSM, CNTF, IL11 and CT1 that utilize the common signaling transducer IL6ST/gp130 for initiating signal transmission. Binding of CNTF to CNTFR recruits the transmembrane components of the co-receptors, IL6ST/gp130 and leukemia inhibitory factor receptor (LIFR), facilitating signal transduction. The CNTF signaling pathway plays a critical role in neuronal cell survival, differentiation and gene expression. Single nucleotide polymorphisms in the CNTFR gene may be associated with variations in muscle strength, as well as early onset of eating disorders.
