Specific for the ~95k dynamin protein phosphorylated at Ser778. This antibody labels the purified protein phosphorylated in vitro by CDK5 but not by PKC. Does not cross react with other purified substrates of CDK5 (e.g. Amphiphysin and Synapsin). Immunolabeling is blocked by lambda-phosphatase treatment.

纯化方法
Sequential Chromatography on phospho- and dephosphopeptide affinity columns.
免疫原
Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser778 of rat Dynamin.
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.Synonyms: DNM, DNM1
