Molecular interactions between the coactivator CBP and the human T-cell leukemia virus Tax protein.
The oncoprotein Tax, encoded by the human T-cell leukemia virus type I (HTLV-I), is required for high-level viral transcription and is strongly linked to HTLV-I-associated malignant transformation. Recent evidence suggests that Tax stimulates HTLV-I transcription through recruitment of the cellular coactivator protein CBP to the HTLV-I promoter, promoting high-level viral replication via the tr...
متن کاملOncogenic transformation by the tax gene of human T-cell leukemia virus type I in vitro.
Human T-cell leukemia virus type I (HTLV-I) is a causative agent of adult T-cell leukemia (ATL). To elucidate the role of HTLV-I in leukemogenesis, we examined the biological activity of a defective HTLV-I provirus with the env-pX 3' long terminal repeat region cloned from leukemic cells of an ATL patient. Transfection experiments showed growth stimulation of NIH 3T3 cells--growing beyond the s...

Inhibition of p53 transactivation function by the human T-cell lymphotropic virus type 1 Tax protein.
Human T-cell lymphotropic virus type 1 (HTLV-1) is the etiologic agent for adult T-cell leukemia. HTLV-1 transforms lymphocytes, and there is increasing evidence that the virus-encoded protein, Tax, plays a primary role in viral transformation. We have shown that wild-type p53 in HTLV-1-transformed cells is stabilized. This study was initiated to directly analyze whether the p53 in HTLV-1-trans...
