| Annotation description: | Figure 2: STORM imaging showed MDGA2 (the endogenous protein was replaced by recombinant tagged counterparts) co-localizes with Homer1c in cultured rat hippocampal neurons at DIV10 and DIV14. Related supplementary figures show validation of shRNA and rescue MDGA constructs in neuronal cultures. Authors note that "AP-MDGA1 and AP-MDGA2 displayed a fairly uniform distribution at DIV 10 and 14, filling the whole dendritic shaft without specific accumulation at synapses, similarly to the negative control GFP-GPI (Figure 2A and C)". MDGAs are GPI-anchored membrane molecules, hence "anchored component of ... membrane" term was selected. |
