Synapsin I, a pre-synaptic marker Synapsin-I, also called Synapsin 1/Syn1, is an ~80 kDa protein (predicted mol. wt. 74.1 kDa) which belongs to the Synapsin family (Synapsin I, Synapsin II, Synapsin III). Synapsins are the evolutionarily conserved phospho-proteins which are associ... Read full blog post. |
