Function: Adapter protein that binds F-actin and DNM1, and thereby plays a role in receptor-mediated endocytosis. Plays a role in the reorganization of the actin cytoskeleton, formation of cell projections, such as neurites, in neuron morphogenesis and synapse formation via its interaction with WASL and COBL. Does not bind G-actin and promote actin polymerization by itself. Required for the formation of organized podosome rosettes
By similarity. May act as a common effector of antigen receptor-signaling pathways in leukocytes. Acts as a key component of the immunological synapse that regulates T-cell activation by bridging TCRs and the actin cytoskeleton to gene activation and endocytic processes. Ref.13
Subunit structure: Interacts with SHANK2, SHANK3 and SYN1. Interacts with FGD1 and DNM1. Interacts with ANKRD54. Interacts with COBL. Interacts with WASL and WIPF1
By similarity. Interacts with MAP4K1 and PRAM1. Ref.1 Ref.14
