Amphiphysin is a nerve terminal-enriched protein thought to be involved in synaptic vesicle endocytosis. One of three amphiphysin homologs, amphiphysin II may interact with amphiphysin I in order to regulate synaptic vesicle endocytosis. During clathrin-mediated endocytosis, amphiphysin has been reported to bind to a component of the clathrin coat, clathrin assembly protein 2. Mutations in the expression of amphiphysin II may be causal to defects in the endocytosis pathway. Expression of amphiphysin II has been observed in neurons along with some endocrine cell types and spermatocytes.

The antibody is raised against human amphiphysin II, but recognizes both amphiphysin I and Amphiphysin II (see Molecular Weight Notes).

Western Blot Analysis: 1:1,000 dilution of this antibody detected Amphiphysin II in 10 µg of mouse brain tissue lysate.

It is well established (Ramjaun, 1997) that both Amphiphysin I and II run substantially slower on SDS-PAGE with a larger apparent molecular weight than the predicted molecular weights.
