This study presents the high-resolution crystal structure of the intracellular domain of T<scene name='10/1060550/Fig_02/1'>GFβR1 in complex with the competitive inhibitor SB505124</scene>. Our findings provide detailed insights into this complex's molecular interactions and structural configuration, elucidating the mechanisms by which SB505124 inhibits TGFβR1 activity. These insights are significant for understanding the regulation of TGF-β signaling, a pathway critically involved in cancer biology.
