▁protein ▁has ▁ 3 4 1 ▁am ino ▁acid ▁resid ues ▁with ▁a ▁mole cular ▁weight ▁of ▁ 3 9 ▁ 3 6 6 . ▁The ▁MR 1 ▁protein ▁is ▁able ▁to ▁bind ▁to ▁mole cules ▁derived ▁from ▁b acter ial ▁rib of la vin ▁b ios yn thesis , ▁and ▁then ▁present ▁it ▁to ▁m uc os al ▁associated ▁invariant ▁T ▁cells ▁for ▁activation . ▁Within ▁cells , ▁MR 1 ▁is ▁mostly ▁stored ▁inside ▁the ▁end op las mic ▁ret icul um , ▁where ▁the ▁binding ▁of ▁b acter ial ▁rib of la vin - related ▁mole cules ▁to ▁MR 1 ▁occurs , ▁causing ▁it ▁to ▁be ▁sent ▁to ▁the ▁cell ▁surface ▁for ▁presentation . ▁A ▁T - cell ▁re ceptor ▁for ▁the ▁MR 1 ▁surface ▁coat ▁protein ▁shows ▁potential ▁for ▁cancer ▁treatment . ▁In ▁ 2 0 2 0 , ▁scient ists ▁worked ▁with ▁MR 1 ▁prote ins ▁and ▁they ▁discovered ▁that ▁they ▁killed ▁all ▁of ▁the ▁cancer ▁types ▁they ▁tested ▁on . ▁ ▁References ▁ ▁Further ▁reading ▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ ▁ ▁Category : H uman ▁prote ins <0x0A> </s> ▁Th i ago ▁Silva ▁( born ▁ 1 9 8 4 ) ▁is ▁a ▁Brazil ian ▁footballer . ▁ ▁Th i ago ▁Silva ▁may ▁also ▁refer ▁to : ▁ ▁Th i ago ▁Silva ▁( fig h ter ) ▁( born ▁ 1 9 8 2 ), ▁Brazil ian ▁kick box er ▁and ▁mixed ▁mart ial ▁artist ▁ ▁Th i ago ▁Silva ▁( football er , ▁born ▁ 1 9 8 3 ), ▁Brazil
