DNA molecules encoding murine son of sevenless (mSOS) gene and mSOS polypeptides

摘要

Isolated DNA molecules comprising a nucleotide sequence encoding murine son of sevenless gene 1 (mSOS1) polypeptide and comprising a nucleotide sequence encoding murine son of sevenless gene 2 (mSOS2) polypeptide are disclosed, as well as isolated mSOS1 polypeptide and isolated mSOS2 polypeptide, and diagnostic methods using the same.
