According to Reactome, this protein belongs to the following pathways:
Adherens junctions interactions  REACT_19195  
Cell-extracellular matrix interactions  REACT_20649  
Formation of annular gap junctions  REACT_11049  
Gap junction degradation  REACT_11035  
Interaction between L1 and Ankyrins  REACT_22266

Note 
In vertebrates 3 main groups of actin isoforms, alpha, beta and gamma have been identified. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins coexist in most cell types as components of the cytoskeleton and as mediators of internal cell motility.
