Background: Isthmin 1/ISM1

Isthimin 1 (ISM1) is adhesion antiangiogenic molecule found in skin, muscosal tissues and immuneregulatory cells (1). Mature mouse ISM1 contains two key domains, a central 45 aa TSP type 1 domain followed by a C-terminal 164 aa AMOP domain, the latter of which is responsible for much of the antiangiogenic function (2). ISM1 was originally characterized in Xenopus, and mouse ISM1 shares a 77% similarity with its frog counterpart. Much greater conservation is seen across mammalian species, with mouse ISM1 sharing 92% and 98% aa sequence identity with human and rat ISM1, respectively. ISM shares various roles in developing embryos, from craniofacial patterning (3) to development of the lung tissues as well as tissue homeostasis in adults (4). In the vascular system, Isthmin 1 has been described as an angiogenesis inhibitor. It inhibits angiogenesis in vitro and in vivo, as well as during tumor progression (5). A dual function of Isthmin 1 has also been described where it exerts pro-survival effect on endothelial cells when immobilized, whereas soluble Isthmin 1 induced endothelial cell apoptosis (6). Our in-house bioassay has showed that ISM-1 can support cortical neuron neurite outgrowth.
