Pleiotrophin(PTN) also known asheparin-binding brain mitogen(HBBM) orheparin-binding growth factor 8(HBGF-8) orneurite growth-promoting factor 1(NEGF1) orheparin affinity regulatory peptide(HARP) orheparin binding growth associated molecule(HB-GAM) is aproteinthat in humans is encoded by thePTNgene.Pleiotrophin is an 18-kDagrowth factorthat has a high affinity forheparin. It is structurally related tomidkineandretinoic acid induced heparin-binding protein. 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.
A synthesized peptide derived from human PTOV1.
A synthesized peptide derived from human PTP1B, corresponding to a region within N-terminal amino acids.
A synthetic peptide from human PTP1B
This gene encodes a member of a small class of prenylated protein tyrosine phosphatases (PTPs), which contain a PTP domain and a characteristic C-terminal prenylation motif. The encoded protein is a cell signaling molecule that plays regulatory roles in a variety of cellular processes, including cell proliferation and migration. The protein may also be involved in cancer development and metastasis. This tyrosine phosphatase is a nuclear protein, but may associate with plasma membrane by means of its prenylation motif. Pseudogenes related to this gene are located on chromosomes 1, 2, 5, 7, 11 and X.
A synthesized peptide derived from human PTP4A1/PRL1, corresponding to a region within C-terminal amino acids.
A synthesized peptide derived from human PTP4A2, corresponding to a region within the internal amino acids.
The protein encoded by this gene belongs to a small class of the protein tyrosine phosphatase (PTP) family. PTPs are cell signaling molecules that play regulatory roles in a variety of cellular processes. PTPs in this class contain a protein tyrosine phosphatase catalytic domain and a characteristic C-terminal prenylation motif. This PTP has been shown to primarily associate with plasmic and endosomal membrane through its C-terminal prenylation.
