Abstract
We examined the cellular protein(s) which can associate with Rex protein of human T cell leukemia virus type I (HTLV-I), using Rex-maltose binding protein (MBP) fusion protein. Immunoprecipitation of RexMBP with anti-MBP antibody revealed that a 24 kD protein (p24) associated with RexMBP only in the presence of Rex-responsive mRNA, The fact that p24 was present in both the nucleus and the cytoplasm is consistent with a role of Rex in the nucleo-cytoplasmic transport of viral mRNAs. P24 did not interact with nonfunctional Rex mutant proteins even if they had RNA binding activity in vitro. These results suggest the possible involvement of p24 in the Rex function through a complex formation with Rex on Rex-responsive mRNA.
