Extended Data Fig. 7: Export factors bind to the flexible or protruding regions of rRNA and connect different domains of rRNAs.
From: Nuclear export of pre-60S particles through the nuclear pore complex
a, Mex67-Mtr2-1 connects the ___domain IV and ___domain VI through interactions with ES27 and H101ES41. b, Mex67-Mtr2-2 simultaneously interacts with 5S RNA, H38 from ___domain II and the L1 stalk from ___domain V. c, The ___domain I, ___domain III and the 5.8S RNA are bridged by Mex67-Mtr2-3. d-e, Nmd3 is enclosed by ___domain II, ___domain IV and ___domain V through extensive interactions with H38, H68, H75, H80-81, H89 and H93. f, Ecm1 connects scaffolds ___domain II, ___domain IV and ___domain V by binding to H75, H62, H66, H67 and L1 stalk. g, Tma16 bridges the ___domain II, ___domain V and 5S RNA to prevent the pre-maturation of the CP and P0 stalk. h, Alb1 links the 5.8S RNA, ___domain I and ___domain VI through interactions with H2, H19, H24, H25, H94 and H98. i, Bud20 is clamped between the H61-H63 from ___domain IV and H96 from ___domain VI. j, Arx1 is sandwiched by the flexible ES27 from ___domain IV, H12 and H24 from ___domain I and H59 from ___domain III. Export factors and rRNAs are shown in surface and cartoon representation, respectively. Different export factors and rRNA domains are color coded.
