Sheep anti-Rat Dynamin (Ser774) Polyclonal Antibody | anti-DNM1 antibody

Anti-Phospho-Ser774 Dynamin

Cat. Num. AAA72785

• Gene Names: Dnm1; Dnm
• Reactivity: Rat
• Applications: Immunohistochemistry, Immunofluorescence, Western Blot
• Purity: Affinity Purified (Prepared from sheep serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.)
• Synonyms: Dynamin (Ser774), Antibody; Anti-Phospho-Ser774 Dynamin; anti-DNM1 antibody

• Host: Sheep
• Reactivity: Rat
• Clonality: Polyclonal
• Specificity: Specific for the ~95k dynamin protein phosphorylated at Ser774. 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.
• Purity/Purification: Affinity Purified (Prepared from sheep serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.)
• Form/Format: 100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug BSA per ml and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.
• Sequence Length: 851

• Applicable Applications for anti-DNM1 antibody: IHC (Immunohistochemistry), IF (Immunofluorescence), WB (Western Blot)
• Antigen: Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser774 of rat dynamin.
• Immunogen Information: Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser774 conjugated to KLH
• Immunogen Species: Rat
• Reactivity Assumed Based on 100% Sequence Homology: Bovine, canine, chicken, human, mouse and non-human primates
• Species Reactivity Note: The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, canine, chicken, human, mouse and non-human primates based on the fact that these species have 100% homology with the amino acid sequence used as antigen.
• Biological Significance: 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)
• Preparation and Storage: For long term storage -20 degree C is recommended. Stable at -20 degree C for at least 1 year.
