An ATIPical family of angiotensin II AT2 receptor-interacting proteins

Trends Endocrinol Metab. 2010 Nov;21(11):684-90. doi: 10.1016/j.tem.2010.08.009.


AT2, the second subtype of angiotensin II receptors, is a major component of the renin-angiotensin system involved in cardiovascular and neuronal functions. AT2 belongs to the superfamily of G protein-coupled receptors, but its intracellular signaling pathways have long remained elusive. Over the past few years, efforts to characterize this atypical receptor have led to the identification of novel molecular scaffolds that directly bind to its intracellular tail. The present review focuses on a family of AT2 receptor-interacting proteins (ATIPs) involved in neuronal differentiation, vascular remodeling and tumor suppression. Recent findings that ATIPs and ATIP-related proteins associate with microtubules suggest that they might constitute a novel family of multifunctional proteins regulating a wide range of physiopathological functions.
