Overview
ACTN1 a cytoskeletal protein of the spectrin superfamily. An actin-binding protein with multiple roles in different cell types. A nonmuscle isoform structurally similar to the erythroid beta spectrin gene. Note: This description may include information from UniProtKB.
Protein type: Cytoskeletal protein; Motility/polarity/chemotaxis
Cellular Component: extracellular space; focal adhesion; dendritic spine; extracellular region; pseudopodium; fascia adherens; Z disc; cytosol; ruffle; cell projection; cytoskeleton; cytoplasm; plasma membrane; nucleus
Molecular Function: integrin binding; actin filament binding; protein domain specific binding; protein binding; double-stranded RNA binding; calcium ion binding; vinculin binding
Biological Process: regulation of apoptosis; focal adhesion formation; actin crosslink formation; actin filament bundle formation; platelet activation; extracellular matrix organization and biogenesis; platelet degranulation; negative regulation of cell motility; blood coagulation
Reference #:  P12814 (UniProtKB)
Alt. Names/Synonyms: actinin 1 smooth muscle; actinin, alpha 1; ACTN1; alpha-actinin 1; Alpha-actinin cytoskeletal isoform; Alpha-actinin-1; FLJ40884; FLJ54432; Non-muscle alpha-actinin-1
