Summary: Enables several functions, including ionotropic glutamate receptor binding activity; modification-dependent protein binding activity; and molecular condensate scaffold activity. Involved in several processes, including aggrephagy; brown fat cell proliferation; and positive regulation of long-term synaptic potentiation. Acts upstream of or within negative regulation of transcription by RNA polymerase II. Located in several cellular components, including aggresome; sperm midpiece; and vacuole. Is active in intracellular non-membrane-bounded organelle. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; limb; and sensory organ. Used to study Paget's disease of bone. Human ortholog(s) of this gene implicated in Paget's disease of bone; Paget's disease of bone 3; distal myopathy with rimmed vacuoles; frontotemporal dementia and/or amyotrophic lateral sclerosis 3; and neurodegeneration with ataxia, dystonia, and gaze palsy, childhood-onset. Orthologous to human SQSTM1 (sequestosome 1). [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.
