WebApr 7, 2024 · GRB2 associates with son of sevenless homolog 1 (SOS1), a RasGEF ubiquitously expressed in mammalian cells, to mediate RAS activation6,8. Interestingly, another study conducted in BaF3 and 32D myeloid cell lines stably expressing Y177F BCR-ABL1 demonstrated that although GRB2 binding was abolished, RAS activation was not … WebSon of sevenless homolog 1 (SOS1) is a gene that encodes a protein that functions as a guanine nucleotide exchange factor for Ras proteins. The protein regulates RAS proteins by mediating the exchange of GTP to GDP. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed ...

WebActivation of the sevenless protein-tyrosine kinase is required for the proper specification of R7 photoreceptors in the Drosophila eye. The activation of a Ras protein, p21Ras1, is a crucial early event in the signaling pathway, and constitutive activation of p21Ras1 is sufficient to induce all of the effects of sevenless action.
