Annotation description:Immunoblotting of rat brain subcellular fractions indicates the presence of RhoB in synaptosomes.
11/01/2021 Dnyanada: The paper detects RhoB in the crude synaptic vesicle fraction (Sy) and the membrane-bound compartment fraction (Sy Mb) of the rat brain using a polyclonal antibody against RhoB. The quality of the images used in the additional literature field (PMID: 20203211) isn't optimal; and the juxtaposition with synaptophysin & colocalisation with PSD95 isn't robust to qualify the annotation to the SynGO term 'postsynapse'.
Based on this, the generic term "synapse" was chosen.

Additional literature:Fig 3. Immunocytochemical labelling of cultured corticohippocampal neurons dually labelled for RhoB with synaptophysin or PSD95. RhoB signals show apposition with synaptophysin and colocalisation of RhoB with PSD95, indicating postsynaptic localisation of RhoB. @ PMID:20203211
