Summary: Predicted to enable ionotropic glutamate receptor binding activity and protease binding activity. Involved in anterograde dendritic transport; regulation of myoblast differentiation; and regulation of postsynaptic membrane neurotransmitter receptor levels. Located in acrosomal membrane and caveola. Part of flotillin complex. Is active in glutamatergic synapse. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system. Orthologous to human FLOT2 (flotillin 2).

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.
