RSU1 encodes a protein that is involved in the Ras signal transduction pathway, growth inhibition, and nerve-growth factor induced differentiation processes, as determined in mouse and human cell line studies. In mouse, the encoded protein was initially isolated based on its ability to inhibit v-Ras transformation. Multiple alternatively spliced transcript variants for this gene have been reported; one of these variants was found only in glioma tumors. [provided by RefSeq].
UniProtKB/Swiss-Prot: RSU1_HUMAN, Q15404

Function: Potentially plays a role in the Ras signal transduction pathway. Capable of suppressing v-Ras transformation in vitro
