Amphiphysin is a protein that in humans is encoded by the AMPH gene.[5][6]
Function
This gene encodes a protein associated with the cytoplasmic surface of synaptic vesicles. A subset of patients with
stiff person syndrome who were also affected by breast cancer are positive for autoantibodies against this protein. Alternate splicing of this gene results in two transcript variants encoding different isoforms. Additional splice variants have been described, but their full length sequences have not been determined.[6]
Amphiphysin is a brain-enriched
tissue
and is involved in the formation and stabilization of the T-tubule network. In other tissues amphiphysin is likely involved in other membrane bending and curvature stabilization events.
Interactions
Amphiphysin has been shown to
interact with DNM1,[7][8][9][10][11] Phospholipase D1,[12] CDK5R1,[13] PLD2,[12] CABIN1[14] and SH3GL2.[7][15]
