Summary: Enables GTPase activity and protein-membrane adaptor activity. Acts upstream of or within several processes, including Ras protein signal transduction; forebrain astrocyte development; and modulation of chemical synaptic transmission. Located in membrane. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and limb. Used to study several diseases, including Noonan syndrome 3; arteriovenous malformations of the brain; gastrointestinal system cancer (multiple); pancreatic carcinoma (multiple); and reproductive organ cancer (multiple). Human ortholog(s) of this gene implicated in several diseases, including Noonan syndrome (multiple); cardiofaciocutaneous syndrome (multiple); gastrointestinal system cancer (multiple); hematologic cancer (multiple); and lung cancer (multiple). Orthologous to human KRAS (KRAS proto-oncogene, GTPase). [provided by Alliance of Genome Resources, Dec 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.
