HIV-1 infection of nondividing cells through the recognition of integrase by the importin/karyopherin pathway.
The karyophilic properties of the HIV-1 nucleoprotein complex facilitate infection of nondividing cells such as macrophages and quiescent T lymphocytes, and allow the in vivo delivery of transgenes by HIV-derived retroviral vectors into terminally differentiated cells such as neurons. Although the viral matrix (MA) and Vpr proteins have previously been shown to play important roles in this proc...
متن کاملImportin/karyopherin protein family members required for mRNA export from the nucleus.
The yeast Saccharomyces cerevisiae contains three proteins (Kap104p, Pse1p, and Kap123p) that share similarity to the 95-kDa beta subunit of the nuclear transport factor importin (also termed karyopherin and encoded by KAP95/RSL1 in yeast). Proteins that contain nuclear localization sequences are recognized in the cytoplasm and delivered to the nucleus by the heterodimeric importin complex. A s...
متن کاملNuclear localization signal-independent and importin/karyopherin-independent nuclear import of β-catenin
BACKGROUND Control of the nuclear localization of specific proteins is an important mechanism for regulating many signal transduction pathways. Upon activation of the Wnt signaling pathway, beta-catenin localizes into the nucleus and interacts with TCF/LEF-1 (T-cell factor/lymphocyte enhancer factor-1) transcription factors, triggering activation of downstream genes. The role of regulated nucle...
متن کاملEvolutionary and transcriptional analysis of karyopherin beta superfamily proteins.
In eukaryotes, karyopherin beta superfamily proteins mediate nucleocytoplasmic transport of macromolecules. We investigated the evolutionary and transcriptional patterns of these proteins using bioinformatics approaches. No obvious homologs were found in prokaryotes, but an extensive set of beta-karyopherin proteins was found in yeast. Among 14 beta-karyopherins of Saccharomyces cerevisiae, eig...
متن کاملN-terminally truncated POM121C inhibits HIV-1 replication
Recent studies have identified host cell factors that regulate early stages of HIV-1 infection including viral cDNA synthesis and orientation of the HIV-1 capsid (CA) core toward the nuclear envelope, but it remains unclear how viral DNA is imported through the nuclear pore and guided to the host chromosomal DNA. Here, we demonstrate that N-terminally truncated POM121C, a component of the nucle...
