RasGrf1 na RasGrf2 nibintu byiganjemo inyamaswa z’inyamabere za guanine nucleotide zo guhana zishobora gukora Ras cyangwa Rho GTPase yihariye.Ingirabuzimafatizo za RasGrf zigaragara cyane muri sisitemu yo hagati yo hagati, nubwo imvugo yihariye yinzige ishobora no kugaragara ahandi.RasGrf1 ni gene igaragazwa na papa, gene yacapuwe igaragazwa nyuma yo kuvuka.Ibinyuranye, RasGrf2 ntabwo yacapishijwe kandi yerekana uburyo bwagutse bwo kwerekana.Isoforms zitandukanye kuri genes zombi nazo zirashobora kugaragara mubice bitandukanye bya selile.Poroteyine za RasGrf zigaragaza imiterere ya modular igizwe na domaine nyinshi zirimo CDC25H na DHPH zifite intego yo guteza imbere ivunjisha rya GDP / GTP, ku ntego za Ras cyangwa Rho GTPase.Indangarugero zitandukanye ningirakamaro kugirango zisobanure ibikorwa byazo byo guhanahana amakuru no guhindura umwihariko wibikorwa byabo kugirango uhuze ibimenyetso bitandukanye byo hejuru bigana ku ntego zitandukanye zo hasi no gusubiza.Nubwo bahuje ibitsina, RasGrf1 na RasGrf2 berekana intego zitandukanye zihariye hamwe ninshingano zidahuzagurika mubikorwa bitandukanye byerekana ibimenyetso bijyanye no gukura kwakagari no gutandukana kimwe nibyishimo bya neuronal hamwe nibisubizo cyangwa plastike ya synaptic.Mugihe RasGrfs zombi zishobora gukoreshwa na reseptor ya glutamate, reseptor ya G-protein ihujwe cyangwa impinduka ziterwa na calcium yo mu nda, gusa RasGrf1 ivugwa ko izakorwa na LPA, cAMP, cyangwa agonist-ikora Trk hamwe na reseptor ya urumogi.Isesengura ryimbeba zitandukanye za knockout ryerekanye uruhare rwihariye rwa RasGrf1 mubikorwa byo kwibuka no kwiga, gufotora, kugenzura imikurire ya nyuma yo kuvuka nubunini bwumubiri hamwe na pancreatic β-selile imikorere na glucose homeostasis.Kuri RasGrf2, uruhare rwihariye mukwirakwiza lymphocyte, T-selile yerekana ibisubizo hamwe na lymphomagenezi byasobanuwe.
