Functions of the multi-interacting protein KIDINS220/ARMS in cancer and other pathologies

Abstract

Development of an organ and subsequently the whole system from an embryo is a highly integrated process. Although there are evidence that different systems are interconnected during developmental stages, the molecular understanding of this relationship is either not known or only to a limited extent. Nervous system development, amongst all, is maybe the most crucial and complex process. It relies on the correct distribution of specific neuronal growth factors and hormones to the specific receptors. Among the plethora of proteins that are involved in downstream signalling of neuronal growth factors, we find the Kinase-D Interacting Substrate of 220 kDa (KIDINS220), also known as Ankyrin-rich Repeat Membrane Spanning (ARMS) protein. KIDINS220 has been shown to play a substantial role in the nervous system and vascular system development as well as in neuronal survival and differentiation. It serves as a downstream regulator for many important neuronal and vascular growth factors such as Vascular Endothelial Growth Factor (VEGF), the neurotrophin family, glutamate receptors and ephrin receptors. Moreover, activation and differentiation of B- and T-cells, as well as tumour cell proliferation has also shown to be related KIDINS220. This review comprehensively summarises the existing research data on this protein, with a particular interest in its role in cancer and in other pathologies. This article is protected by copyright.
