The disease is caused by variants affecting the gene represented in this entry. Function RASM_HUMAN Serves as an important signal transducer for a novel upstream stimuli in controlling cell proliferation. Activates the MAP kinase pathway. Publication Abstract from PubMed M-RAS plays a crucial role in the RAF-MEK signaling pathway. When activated by GTP, M-RAS forms a complex with SHOC2 and PP1C, initiating downstream RAF-MEK signal transduction. In this study, the crystal structure of the GDP-bound human M-RAS protein is presented with two forms of crystal packing. Both the full-length and truncated human M-RAS structures aligned well with the high-confidence section of the AlphaFold2-predicted structure with low r.m.s.d., except for the Switch regions. Despite high sequence similarity to the available mouse M-RAS structure, the full-length human M-RAS structure exhibits unique crystal packing. This inactive human M-RAS structure could offer novel insights for the design of selective compounds targeting M-RAS.
