SOS2 (son of sevenless homolog 2) is a human paralog of the Drosophila SOS gene. Drosophila SOS was originally identified as a gene that functioned downstream of the sevenless gene in the Ras/MAP kinase signaling pathway. SOS and its paralogs, SOS1 and SOS2, function as guanine nucleotide exchange factors that act on Ras-GTPases to cause release of GDP in exchange for GTP. Although targeted disruption of SOS1 results in embryonic lethality, disruption of SOS2 does not have any effects on mouse development, growth, or fertility.
Alternative names for
SOS2 Antibody include SOS2 antibody, SOS-1 antibody, son of sevenless ortholog 2 antibody.
