Pleiotrophin (P63089)

Uniprot ID P63089
Protein Name Pleiotrophin
Gene Name Ptn
Species Mus musculus (Mouse)
Signal peptide(a) Y Secretome P(b) 0.453
Function Secreted growth factor that induces neurite outgrowth and which is mitogenic for fibroblasts, epithelial, and endothelial cells. Binds anaplastic lymphoma kinase (ALK) which induces MAPK pathway activation, an important step in the anti-apoptotic signaling of PTN and regulation of cell proliferation. Binds to cell-surface target proteins via their chondroitin sulfate groups. Down-regulates PTPRZ1 activity. .

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
