Biological Significance
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 GFRa (a1-a4) receptors. The GFRa4 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.
Bioactivity
The ED50 was determined by its ability to stimulate proliferation of human thyroid carcinoma cells (TT cells) is 1 x 10^7 units/mg.
Endotoxin Levels
Endotoxin level is less than 0.1 ng per ug (1 EU/ug).
Expression System
E Coli
Preparation and Storage
Store at 4 degree C until reconstitution. Following reconstitution aliquot and freeze at -20 degree C for long term storage. Avoid repeated freeze/thaw cycles.

NCBI Description

The protein encoded by this gene is a neurotrophic factor, belonging to the GDNF family. Neurotrophic factors are important for the proper development and maintenance of the nervous system. These factors promote neuronal survival and can prevent the neuronal degeneration associated with injury, toxin exposure, or neurodegenerative disease. The encoded protein has amino acid similarity to its other family members, glial cell line-derived neurotrophic factor and neurturin. This gene product promotes the survival of ventral midbrain dopaminergic neurons in culture and prevents their degeneration after 6-hydroxydopamine treatment in vivo. [provided by RefSeq, Jul 2008]

Product Notes

The PSPN pspn (Catalog #AAA539566) is an Active Protein produced from Human and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Persephin can be used in a range of immunoassay formats including, but not limited to, User optimized. Researchers should empirically determine the suitability of the PSPN pspn for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Region of Persephin protein correspond ing to amino acids ALAGSCRLWS LTLPVAELGL GYASEEKVIF RYCAGSCPQE ARTQHSLVLA RLRGRGRAHG RPCCQPTSYA DVTFLDDQHH WQQLPQLSAA ACGCGG. It is sometimes possible for the material contained within the vial of "Persephin, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
