일반 설명
Persephin is a disulfide-linked homodimer neurotrophic factor structurally related to glial cell line-derived neurotrophic factor (GDNF), artemin, and neurturin. These proteins belong to the cysteine-knot family of growth factors that assume stable dimeric structures. Persephin signals through a multicomponent receptor system, composed of RET and one of four GFRa (a1-a4) receptors. The GFRa4 was first identified in chicken and was later shown to be the preferential binding subunit for Persephin. The gene coding for persephin is localized on human chromosome 19p13.3.[1] Recombinant human persephin is a disulfide-linked homodimer, composed of two 10.3kDa polypeptide chains (192 total amino acid residues). Each chain contains seven conserved cysteine residues, one of which (Cys 63) is used for inter-chain disulfide bridging and the others are involved in intramolecular ring formation known as the cysteine knot configuration.

Glial cell line-derived neurotrophic factor (GDNF) family ligands (GFL) are potent survival factors and regulators for central and peripheral neurons. GFLs bind to specific glycosyl phosphatidylinositol (GPI)-anchored co-receptors (GFRalpha1-alpha4), but signal through a common c-Ret receptor. Both GPI-anchored and soluble

Members of the GDNF protein family signal through receptors consisting of a GPI-linked GFRalpha subunit and the transmembrane tyrosine kinase Ret. Here we characterize the mouse Gfra4 and show that it undergoes developmentally regulated alternative splicing in several tissues. The
