Dynamin

Dynamin is a 100kD GTP binding protein that was first identified as a protein able to bind microtubules. A mutation in the Drosophila gene shits, encoding a dynamin homolog, prevents synaptic vesicle recycling and causes temperature-sensitive paralysis, implicating dynamin in the formation of coated vesicles. Dynamin may mediate vesicle formation by assembling into a ring structure around the necks of invaginated coated pits that may eventually lead to the closure of the neck and formation of vesicles. Amphiphysin, dynamin, clathrin and AP2 form a complex during synaptic vesicle endocytosis, which is regulated by the phosphorylated state of different components in this comple. To date, three genes have been found to encode dynamin isoforms. Dynamin 1 is neuronal specific. Dynamin 2 is ubiquitously expressed. Dynamin 3 localizes to testis, brain and lung.\n \nApplications:\nSuitable for use in Western Blot, Flow Cytometry, Immunoprecipitation and Immunohistochemistry. Other applications have not been tested.\n\nRecommended Dilutions:\nWestern Blot (Colorimetric): 0.5ug/ml\nFlow Cytometry: 10ug/ml\nImmunohistochemistry: 1:50; Stains human colon cancer tissue. Staining of formaldehyde perfused and fixed rat brain shows synaptic immunofluorescence.\nOptimal dilutions to be determined by the researcher.\n \nPositive Control:\nMouse Brain Tissue Extract \n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
