However, whether VEGFR2 is regulated by additional coreceptors is not clear. To investigate whether SCUBE2 (signal peptide-CUB-EGF domain-containing protein 2), a peripheral membrane protein expressed in vascular endothelial cells (ECs) known to bind other signaling receptors, functions as a VEGFR2 coreceptor and to verify the role of SCUBE2 in the VEGF-induced angiogenesis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Approach and Results\u2014<\/jats:title>\n            <jats:p>\n              SCUBE2 lentiviral overexpression in human ECs increased and short hairpin RNA knockdown inhibited VEGF-induced EC growth and capillary-like network formation on Matrigel.

Coimmunoprecipitation and ligand-binding assays showed that SCUBE2 forms a complex with VEGF and VEGFR2, thus acting as a coreceptor to facilitate VEGF binding and augment VEGFR2 signal activity. SCUBE2 knockdown or genetic knockout suppressed and its overexpression promoted the VEGF-induced activation of downstream proangiogenic and proliferating signals, including VEGFR2 phosphorylation and mitogen-activated protein kinase or AKT activation.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Endothelial SCUBE2 may be a novel coreceptor for VEGFR2 and potentiate VEGF-induced signaling in adult angiogenesis.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/atvbaha.116.308546","type":"journal-article","created":{"date-parts":[[2016,11,14]],"date-time":"2016-11-14T11:06:44Z","timestamp":1479121604000},"page":"144-155","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":43,"title":["Endothelial SCUBE2 Interacts With VEGFR2 and Regulates VEGF-Induced Angiogenesis"],"prefix":"10.1161","volume":"37","author":[{"given":"Yuh-Charn","family":"Lin","sequence":"first","affiliation":[{"name":"From the Institute of Biomedical Sciences, Academia Sinica, Taipei, Taiwan (Y.-C.L., S.R.R., R.K., R.-B.Y.);
