Summary: Enables SH3 domain binding activity and epidermal growth factor receptor binding activity. Involved in several processes, including Ras protein signal transduction; neurotrophin TRK receptor signaling pathway; and positive regulation of signal transduction. Located in neuronal cell body. Is active in glutamatergic synapse and postsynaptic density. Used to study brain ischemia. Human ortholog(s) of this gene implicated in Noonan syndrome; Noonan syndrome 4; atrial heart septal defect; gingival fibromatosis; and pulmonary valve stenosis. Orthologous to human SOS1 (SOS Ras/Rac guanine nucleotide exchange factor 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
