摘要

肝素亲和调节肽(Heparin affin regulatory peptide, HARP),又称多肽(Pleiotrophin, PTN),是一种对肝素具有高亲和力的多肽,与Midkine (MK)具有约50%的序列同源性。根据这种结构同源性,这两个分子构成了一个新的肝素结合蛋白家族。HARP和MK的生物学特性在很大程度上仍然是一个有争议的话题。这两种蛋白质都被描述为神经突生长促进剂,而直到最近,有丝分裂活性一直存在争议。本文综述了有关HARP的研究进展,重点介绍了其有丝分裂特性的最新研究进展。

Biochemical and mitogenic properties of the heparin-binding growth factor HARP

Heparin affin regulatory peptide (HARP), also called Pleiotrophin (PTN), is a polypeptide that displays a high affinity for heparin and that shares approximately 50% sequence homology with Midkine (MK). According to this structural homology, these two molecules constitute a new family of heparin-binding proteins. The biological properties of HARP and MK remain largely a subject of debate. Both proteins have been described as neurite outgrowth promoting agents whereas until recently the mitogenic activity has been controversial. The aim of this review is to summarize the information on HARP with special focus on the recent data relating to its mitogenic properties.
