Chromosomal localization of two genes encoding human ras exchange factors: SOS1 maps to the 2p22-->p16 region and SOS2 to the 14q21-->q22 region of the human genome.
The human SOS1 and SOS2 genes encode proteins that control GDP-->GTP exchange on ras proteins and are involved in signal transduction by tyrosine kinase receptors. In situ hybridization shows that SOS1 maps to 2p22-->p16 and SOS2 to 14q21-->q22 in the human genome.
