Recombinant Human Pleiotrophin/PTN Protein Summary

Description
A single non-glycosylated polypeptide chain containing 136 amino acids corresponding to Pleiotrophin/PTN Source: E. coli

Uniprot ID: P21246

Amino Acid Sequence: GKKEKPEKKV KKSDCGEWQW SVCVPTSGDC GLGTREGTRT GAECKQTMKT QRCKIPCNWK KQFGAECKYQ FQAWGECDLN TALKTRTGSL KRALHNAECQ KTVTISKPCG KLTKPKPQAE SKKKKKEGKK QEKMLD
Details of Functionality
Pleiotrophin/PTN protein is fully biologically active when compared to standard. The biological activity was measured by its ability to enhance neurite outgrowth of E16E18 rat embryonic cortical neurons, when neurons were plated on 96 well culture plates that had been precoated with 100 ul/well of a solution of 5-10 ug/ml rHuPTN.

Background

Pleiotrophin, also named heparinbinding brain mitogen (HBBM), is belonging to the heparinbinding proteins family and is encoded by the PTN gene in humans. Pleiotrophin is expressed in an activitydependent manner in the hippocampus. Pleiotrophin expression is low in other areas of the adult brain, but it can be induced by ischemic insults. The cell surfaceexpressed nucleolin is a low affinity receptor for PTN binding to cells and it is also implicated in PTN entry into cells by an active process. Human pleiotrophin shares above 98 % amino acid sequence identity with bovine, rat and murine.
