DAXX interacts with phage PhiC31 integrase and inhibits recombination.

Phage PhiC31 integrase has potential as a means of inserting therapeutic genes into specific sites in the human genome. However, the possible interactions between PhiC31 integrase and cellular proteins have never been investigated. Using pLexA-PhiC31 integrase as bait, we screened a pB42AD-human fetal brain cDNA library for potential interacting cellular proteins.

Identification, expression pattern, and subcellular location of human RIP isoforms.

XRIP alpha was identified as an adapter protein involved in RAP nuclear import. Several homologs were reported in mammal EST analysis, but the expression pattern and genomic organization of hRIP isoforms were not clarified yet. We isolated nine isoforms of hRIP from a premade human fetal brain library.
