Background
Details
The antibody reacts specifically with the N-terminus of synaptopodin/SYNPO, a prolin-rich actin-binding protein with 2 binding sites for actin. Synaptopodin belongs to actin-binding pro-teins, it has first been localized in podocytes and a subset of telencephalic postsynaptic densities. In human tissue synaptopodin has a molecular weight of 73.7 kD and pI of 9.38 (calculated from sequence data); in mouse the corre-sponding data are 74 kD, pI 9.27. In SDS-PAGE the antigen appears as 100 kD polypeptide in brain and 110 kD polypeptide in kidney (attributed to posttransla-tional modifications). In Western blot analysis the antibody also reacts with a 44 kD degradation fragment of synaptopodin.
The antibody recognizes differentiated podocytes (glomerular visceral epithelial cells) in vivo and in vitro (weaker additional reaction with arterial endothelial cells), co-localization with alpha-actinin.
Reacts with a subset of exclusively telencephalic synapses. Differentiation-dependent expression during postnatal maturation of murine brain. Differentiation-dependent expression in cultured hippocampal neurons.
