Figure 3. Structure and binding partners of Nog1.
a, The NTD of Nog1 inserts directly into the two strands of H89. GD, GTPase domain. b, Superimposition of the NTD of Nog1 with H89 in its mature conformation, displaying a steric clash in the terminal tip of the NTD of Nog1. c, Structural comparison of H89 in the pre-60S and mature conformations. d, The CTE of Nog1 interacts with multiple assembly factors (Tif6, Rlp24, Arx1) and r-proteins (L3, L31, L22, L19, L35) in an arc region of the pre-60S particle. The overview is shown in the left thumbnail. The position and direction of polypeptide tunnel exit is denoted by a black diamond. e, The last C-terminal portion of Nog1 goes into the polypeptide tunnel and interacts with L4, L17, and L39 (see also Extended Data Fig. 6).
