Protein Structure

UniProt Annotation

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 (By similarity). {ECO:0000250}.

Subcellular Localization

Secreted.

Disease Associations

Tissue Specificity

Osteoblast and brain. {ECO:0000269PubMed:1701634, ECO:0000269PubMed:1768439}.
