The RASGRP family is composed of RASGRP1\u20134 proteins and activates the small GTPases, RAS and RAP. Among them, RASGRP2 has different characteristics from other RASGRPs in that it targets small GTPases and its localizations are different. Many studies related to RASGRP2 have been reported in cells of the blood cell lineage. Furthermore, RASGRP2 has also been reported to be associated with Huntington\u2019s disease, tumors, and rheumatoid arthritis. In addition, we also recently reported RASGRP2 expression in vascular endothelial cells, and clarified the involvement of xenopus Rasgrp2 in the vasculogenesis process and multiple signaling pathways of RASGRP2 in human vascular endothelial cells with stable expression of RASGRP2. Therefore, this article outlines the existing knowledge of RASGRP2 and focuses on its expression and role in vascular endothelial cells, and suggests that RASGRP2 functions as a protective factor for maintaining healthy blood vessels.<\/jats:p>","DOI":"10.3390\/ijms222011129","type":"journal-article","created":{"date-parts":[[2021,10,15]],"date-time":"2021-10-15T13:35:47Z","timestamp":1634304947000},"page":"11129","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["The Role of RASGRP2 in Vascular Endothelial Cells\u2014A Mini Review"],"prefix":"10.3390","volume":"22","author":[{"given":"Jun-ichi","family":"Takino","sequence":"first","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, Hiroshima International University, 5-1-1 Hirokoshingai, Kure, Hiroshima 737-0112, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shouhei","family":"Miyazaki","sequence":"additional","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, Hiroshima International University, 5-1-1 Hirokoshingai, Kure, Hiroshima 737-0112, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Nagamine","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hiroshima International University, 5-1-1 Hirokoshingai, Kure, Hiroshima 737-0112, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takamitsu","family":"Hori","sequence":"additional","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, Hiroshima International University, 5-1-1 Hirokoshingai, Kure, Hiroshima 737-0112, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"10995","DOI":"10.1074\/jbc.R800061200","article-title":"Specificity in Ras and Rap signaling","volume":"284","author":"Raaijmakers","year":"2009","journal-title":"J.
