Summary: Predicted to enable actin filament binding activity and ankyrin binding activity. Predicted to be involved in actin cytoskeleton organization and modification of postsynaptic actin cytoskeleton. Predicted to act upstream of or within hemopoiesis; plasma membrane organization; and porphyrin-containing compound biosynthetic process. Is active in glutamatergic synapse and postsynapse. Human ortholog(s) of this gene implicated in hereditary spherocytosis and hereditary spherocytosis type 2. Orthologous to human SPTB (spectrin beta, erythrocytic).

What's a GeneRIF?

suggest that betaI-spectrin is a synaptic protein that can modulate both the morphological and functional dynamics of dendritic spines, perhaps via interaction with actin and Rac3.

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.
