Summary
Enables GDP binding activity; GMP binding activity; and LRR domain binding activity. Involved in several processes, including cardiac muscle cell proliferation; positive regulation of NF-kappaB transcription factor activity; and response to corticosteroid. Predicted to be located in cytoplasm and cytoplasmic side of plasma membrane. Predicted to be active in plasma membrane. Used to study bronchiolo-alveolar adenocarcinoma; endometrial adenocarcinoma; hepatocellular adenoma; hepatocellular carcinoma; and renal fibrosis. Biomarker of muscular atrophy. 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, 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.
