(A) A model of human Bicoid interacting 3 domain containing RNA methyltransferase (BCDIN3D)-tRNAHis complex structure. Human BCDIN3D structure was modeled using SWISS-MODEL (Biasini et al., 2014), based on the structure of the catalytic domain of methylphosphate capping enzyme (MePCE) (Jeronimo et al., 2007) as a template model. tRNA was manually docked onto the surface of the modeled BCDIN3D and the 5′-terminal of tRNA can enter the catalytic SAM binding site. BCDIN3D measures the length of the acceptor helix of tRNA. (B) A potential association between methylation of tRNAHis and breast cancer. tRNAHis might have unknown functions, beyond its established function in protein synthesis.
