Summary: Enables guanyl-nucleotide exchange factor activity and protein kinase binding activity. Involved in cell surface receptor signaling pathway and nervous system development. Acts upstream of or within several processes, including cell surface receptor protein tyrosine kinase signaling pathway; circulatory system development; and regulation of T cell activation. Predicted to be located in cytoplasm and neuronal cell body. Predicted to be part of GTPase complex. Predicted to be active in plasma membrane. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; hemolymphoid system gland; and retina. Used to study Noonan syndrome 4. 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.
