The gene was so named because the Sos protein that it encoded was found to operate downstream of the sevenless gene in Drosophila melanogaster in a Ras/MAP kinase pathway. [1] When sevenless is mutated or otherwise dysfunctional during development of the fly's ultraviolet light -sensitive compound eye , the seventh, central photoreceptor (R7 ...

Son of sevenless (SOS1) is an important GEF in the cell growth-regulatory MAPK/ERK pathway. SOS1 binds GRB2 at the plasma membrane after EGF receptor activation. SOS1 activates the small G protein Ras. [17]
RhoGEF domain describes two distinct structural domains with guanine nucleotide exchange factor (GEF) activity to regulate small GTPases in the Rho family.Rho small GTPases are inactive when bound to GDP but active when bound to GTP; RhoGEF domains in proteins are able to promote GDP release and GTP binding to activate specific Rho family members, including RhoA, Rac1 and Cdc42.

Sevenless (sev) is a gene in the fruit fly Drosophila melanogaster that encodes a receptor tyrosine kinase protein essential to the development of the R7 photoreceptor cells in the Drosophila embryonic eye. [1]
