Summary: This gene encodes the beta subunit of the adducin family. Adducins, encoded by alpha, beta and gamma genes, are heteromeric proteins that crosslink actin filaments with spectrin at the cytoskeletal membrane. This protein, primarily found in the brain and hematopoietic cells, is regulated by phosphorylation and calmodulin interactions as it promotes spectrin assembly onto actin filaments, bundles actin and caps barbed ends of actin filaments. In mouse, deficiency of this gene can lead to mild hemolytic anemia and impaired synaptic plasticity. Mutations of this gene in mouse serve as a pathophysiological model for hereditary spherocytosis and hereditary elliptocytosis. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Dec 2012]

Study shows that a single injection of 3 pharmacologically distinct psychoactive drugs can modify spines in the nucleus accumbens within a day. beta-adducin is necessary for these effects. Study suggests that fine regulation of DARPP-32 phosphorylation is a major factor in mediating common effects on beta-adducin of various drugs with distinct or even opposite modes of action.
Title: Acute drug-induced spine changes in the nucleus accumbens are dependent on β-adducin.
Sez6l2 is one of the auxiliary subunits of the AMPA receptor and acts as a scaffolding protein to link GluR1 to ADD. Furthermore, Sez6l2 overexpression upregulates ADD phosphorylation, whereas siRNA-mediated downregulation of Sez612 prevents ADD phosphorylation, suggesting that Sez6l2 modulates AMPA-ADD signal transduction.
Title: Sez6l2 regulates phosphorylation of ADD and neuritogenesis.
Darpp32 interaction with beta-adducin may be the molecular pathway by which environmental changes may rapidly alter responsiveness of striatal neurons involved in the reward system.
Title: DARPP-32 interaction with adducin may mediate rapid environmental effects on striatal neurons.
Calcium plays a role in regulating the expression and function of beta-adducin to sustain normal organization of the spectrin-based cytoskeleton and the differentiation properties in keratinocytes through the calmodulin/EGFR/cadherin signaling pathway.
Title: β-Adducin siRNA disruption of the spectrin-based cytoskeleton in differentiating keratinocytes prevented by calcium acting through calmodulin/epidermal growth factor receptor/cadherin pathway.

Title: Chorein, the protein responsible for chorea-acanthocytosis, interacts with β-adducin and β-actin.
betaAdd-knockout mice show increased dendritic spine density in nucleus accumbens and elevated locomotor activity in response to cocaine.
Title: Constitutive knockout of the membrane cytoskeleton protein beta adducin decreases mushroom spine density in the nucleus accumbens but does not prevent spine remodeling in response to cocaine.
mice lacking beta-Adducin fail to assemble new synapses upon enhanced plasticity and exhibit diminished long-term hippocampal memory upon environmental enrichment.
Title: β-Adducin is required for stable assembly of new synapses and improved memory upon environmental enrichment.
These results strongly suggest coordinated expression and phosphorylation of alpha-, beta-, and gamma-adducins as key mechanism underlying synaptic plasticity, motor coordination performance and learning behaviors.
Title: beta-adducin (Add2) KO mice show synaptic plasticity, motor coordination and behavioral deficits accompanied by changes in the expression and phosphorylation levels of the alpha- and gamma-adducin subunits.
Analysis of 3 new alleles reveals previously unknown consequences of red blood cell (RBC) spectrin deficiency, resulting in markedly reduced RBC membrane spectrin content, decreased band 3, and absent beta-adducin.
Title: Analysis of novel sph (spherocytosis) alleles in mice reveals allele-specific loss of band 3 and adducin in alpha-spectrin-deficient red cells.

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.
