Summary: Enables mitogen-activated protein kinase kinase kinase binding activity; phosphoprotein binding activity; and syntaxin binding activity. Involved in several processes, including insulin receptor signaling pathway; negative regulation of endothelial cell proliferation; and positive regulation of peptidyl-tyrosine phosphorylation. Located in several cellular components, including caveola; lipid droplet; and nuclear inner membrane. Part of protein-containing complex. Biomarker of high grade glioma and obesity. Human ortholog(s) of this gene implicated in low tension glaucoma and primary open angle glaucoma. Orthologous to human CAV2 (caveolin 2). [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.
