General Information of Binding Target of SBP (BTS) (ID: ST00011)
BTS Name
Son of sevenless homolog 1
Synonyms
SOS-1
BTS Type
Protein
Gene Name
SOS1
Organism
Homo sapiens (Human)
Function
Promotes the exchange of Ras-bound GDP by GTP Probably by promoting Ras activation, regulates phosphorylation of MAP kinase MAPK3 in response to EGF Catalytic component of a trimeric complex that participates in transduction of signals from Ras to Rac by promoting the Rac-specific guanine nucleotide exchange factor (GEF) activity (By similarity).
