Short name: ADD2

Overlapping homologous superfamilies

Family relationships



Adducin is a cytoskeletal protein that regulates the assembly of the spectrin-actin subcortical membrane network [PMID: 7642559]. Adducin is present as a heterotetramer formed by two alpha subunits non covalently linked to two beta or, alternatively, to two gamma subunits depending on the cell type. Each subunit is comprised of three regions: a NH2-terminal protease-resistant globular head region, a short connecting subdomain, and a protease-sensitive tail region. Adducin is a substrate for protein kinase A and C (PKA, PKC) and tyrosine kinase phosphorylation and is involved in calcium cycling control, cell-to-cell contact, signal transduction, and cell motility [PMID: 11895774].

This entry represents the beta-adducin. The protein is involved in synaptic plasticity in the hippocampus, and may have a role in stabilising dentritic spines once drug- or experience-dependent remodeling has occurred [PMID: 23106536].
