摘要: The subcellular localization of the mouse type IV c-abl protein was determined by indirect immunofluorescence nontransformed NIH 3T3 fibroblasts that overexpress protein. Unlike viral transforming p160gag/v-abl, which has cytoplasmic and plasma membrane localization, a large fraction (IV) is nuclear, with remainder in cytoplasm membrane. Deletion small N-terminal regulatory region protein, sufficient to activate its potential fully, changes distribution from nucleus cytoplasm. Mapping an amino acid sequence responsible for nuclear reveals signal similar SV40 T antigen.
