Phospho-Dynamin 1 (Ser774) Sheep anti-Rat, Polyclonal, Invitrogen
Sheep Polyclonal Antibody
Manufacturer: Invitrogen PA14620
This antibody is predicted to react with bovine, canine, chicken, human, mouse and non-human primate based on 100% sequence homology. It does not cross-react with other purified substrates of cdk5 (amphiphysin and synapsin). This antibody is specific for the ~95 kDa Dynamin protein phosphorylated at Ser774in Western blots of rat brain lysates. This antibody labels the purified protein phosphorylated in vitro by cdk5 but not by PKC. Immunolabeling is blocked by the phosphopeptide used as the antigen but not by the corresponding dephosphopeptide. Store at -20°C short term, 80°C long term.Dynamin is a member of a group of nerve terminal proteins called dephosphins that regulate synaptic vesicle endocytosis Cousin et al., 2001; Graham et al., 2002; Tsuboi et al., 2002). Cyclin dependent protein kinase 5 phosphorylates dynamin at Ser774 and Ser778 that are the phosphorylation sites on dynamin phosphorylated in vivo (Tan et al., 2003). Phosphorylation of these sites on dynamin is thought to play a key role in synaptic vesicle trafficking.
