Gene Name | DNM1 |
Other Names | Dynamin-1, B-dynamin, D100, Dynamin, brain, Dnm1, Dnm |
Target/Specificity | Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser774 conjugated to KLH. |
Dilution | WB~~ 1:1000 |
Format | Prepared from sheep serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns. |
Antibody Specificity | Specific for the ~95k dynamin protein phosphorylated at Ser774. Labelsthe purified protein phosphorylated in vitro by cdk5 but not by PKC. Does not cross react withother purified substrates of cdk5 (e.g. amphiphysin and synapsin). Immunolabeling is blockedby λ-phosphatase treatment. |
Storage | Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles. |
Precautions | Phospho-Ser774 Dynamin Antibody is for research use only and not for use in diagnostic or therapeutic procedures. |
Shipping | Blue Ice |

Background
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 Ser774 by GSK3 has recently been shown to control activity-dependent bulk endocytosis of synaptic vesicles (Clayton et al., 2010)
