A number of cytoskeletal proteins are tyrosine phosphorylated in Rous sarcoma virus-transformed chick embryo fibroblasts. One of these is
the 68 kDa paxillin protein. Paxillin is a cytoskeletal component that localizes to the focal adhesions at the ends of actin stress fibers. It is also
present in the focal adhesions of Madin-Darby canine kidney epithelial cells, but is absent from the cell adherens junctions of these cells.
Paxillin purified from chicken gizzard migrates as a diffuse band on SDS-PAGE with molecular weight of 65-70 kDa. It binds to the rod
domain of vinculin, another focal adhesion protein. It is thought that phosphorylation of paxillin may have a role in that disassembly of focal
adhesions and stress fibers during transformation.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
