Purified recombinant Human Persephin protein
Expression System: E.coli
Bioactivity: Human Persephin induces RET phosphorylation using a concentration range of 0.1-1.0 ng/mL. Human Persephin binds to mammalian GFRa4 with the Kd of 100 pM. Other members of the GDNF family (Artemin, GDNF and Neurturin) do not bind to mammalian GFRa4. - Purity
- > 98 % pure
- Endotoxin Level
- < 0.1 ng per µg (1 EU/µg).

- Background
-
Persephin is a disulfide-linked homodimer neurotrophic factor structurally related to 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 GFR alpha (alpha1-alpha4) receptors. The GFRalpha4 was first identified in chicken and was later shown to be the preferential binding subunit for Persephin. Persephin promotes the survival of ventral midbrain dompaminergic neurons and motor neurons after sciatic nerve oxotomy, and like GNDF, promotes ureteric bud branching. However, in contrast to GDNF and Neurturin, Persephin does not support survival of peripheral neurons.
