Summary: Predicted to enable ionotropic glutamate receptor binding activity and protease binding activity. Involved in several processes, including positive regulation of cell-cell adhesion mediated by cadherin; positive regulation of cellular component organization; and positive regulation of dopaminergic synaptic transmission. Acts upstream of or within axonogenesis and regulation of Rho protein signal transduction. Located in caveola; external side of plasma membrane; and sarcolemma. Part of flotillin complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human FLOT1 (flotillin 1).

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.
