| Abstract: | With differential and sucrose density gradient centrifugations, total rat nonnuclear sarcoplasmic membranes were purified. 32 P DNA overlay technique revealed the presence of a 29kDa protein that bounds closed circular (cc) and linearized(L) double stranded DNA specifically in total rat sarcoplasmic membranes. The DNA binding activities could be completely inhibited by the presence of unlabled CC or L double stranded DNA. The membrane associated DNA binding protein may involve in the skeletal muscle mediated gene transfer. |
