特異性：Recognizes differentiated podocytes (glomerular visceral epithelial cells) in vivo and in vitro (weaker additional reaction with arterial endothelial cells), co-localization with alpha-actinin. Does not react with parietal cells. Reacts with a subset of exclusively telencephalic synapses. Differentiation-dependent expression during postnatal maturation of rat brain. Differentiation-dependent expression in cultured hippocampal neurons. Reacts specifically with synaptopodin, a prolin-rich actin-binding protein with 2 binding sites for actin. Cross-reacts with human, bovine, rat, mouse, guinea pig and gerbil. Does not cross-react with rabbit, frog or chicken.
