Summary: This gene encodes a secreted ligand of the GDNF (glial cell line-derived neurotrophic factor) subfamily and TGF-beta (transforming growth factor-beta) superfamily of proteins. The encoded preproprotein is proteolytically processed to generate the mature protein. This protein signals through the RET receptor tyrosine kinase and a GPI-linked coreceptor, and promotes survival of neuronal populations. This protein may play a role in cell death, and nervous system development and function. Elevated expression of this gene has been observed in oral squamous cell carcinoma.

What's a GeneRIF?

Results suggested that PSPN is a possible key regulator of oral squamous cell carcinoma (OSCC) progression via PSPN-RET-mitogen-activated protein kinase activation and that PSPN overexpression may have diagnostic potential for OSCC.
Title: Persephin: A potential key component in human oral cancer progression through the RET receptor tyrosine kinase-mitogen-activated protein kinase signaling pathway.
Results identify persephin, a GDNF family member, as a novel ligand for GFRalpha1/RET receptor complex.
Title: Persephin signaling through GFRalpha1: the potential for the treatment of Parkinson's disease.
No differences were found in the allelic frequencies of the variants or in the haplotype distribution between Hirschsprung's disease patients & controls, nor to any demographic/clinical parameters within the group of patients.

Title: Polymorphisms in the genes encoding the 4 RET ligands, GDNF, NTN, ARTN, PSPN, and susceptibility to Hirschsprung disease.
The results obtained suggest the involvement of NTN, PSP, and ART in processes subserving both the organization of this cortical region during development and the functional activity and maintenance of the mature human hippocampal neurons.
Title: Neurturin, persephin, and artemin in the human pre- and full-term newborn and adult hippocampus and fascia dentata.
Persephin/GFRalpha4 is unable to recruit RET protein into lipid rafts.
Title: PSPN/GFRalpha4 has a significantly weaker capacity than GDNF/GFRalpha1 to recruit RET to rafts, but promotes neuronal survival and neurite outgrowth.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
