| Description | disease:A chromosomal aberration involving PSIP1 is associated with pediatric acute myeloid leukemia (AML) with intermediate characteristics between M2-M3 French-American-British (FAB) subtypes. Translocation t(9;11)(p22;p15) with NUP98. The chimeric transcript is an in-frame fusion of NUP98 exon 8 to PSIP1/LEDGF exon 4.,domain:Residues 340-417 are necessary and sufficient for the interaction with HIV-1 IN (IBD domain).,function:Transcriptional coactivator involved in neuroepithelial stem cell differentiation and neurogenesis. Involved in particular in lens epithelial cell gene regulation and stress responses. May play an important role in lens epithelial to fiber cell terminal differentiation. May play a protective role during stress-induced apoptosis. Isoform 2 is a more general and stronger transcriptional coactivator. Isoform 2 may also act as an adapter to coordinate pre-mRNA splicing. Cellular cofactor for lentiviral integration.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,similarity:Belongs to the HDGF family.,similarity:Contains 1 PWWP domain.,subcellular location:Remains chromatin-associated throughout the cell cycle.,subunit:Monomer. Interacts with IFRD1/PC4. Isoform 2 interacts with SFRS1. Isoform 1 interacts with lentiviral integrase and acts as a chromatin tethering factor to the chromosomal DNA. Isoform 1 interacts in particular with the human HIV-1 integrase protein (HIV-1 IN), determining its nuclear localization, its tight association with chromatin and its protection from the proteasome. Isoform 1 interacts also with HIV-2 IN. Isoform 2 does not interact with HIV-1 IN.,tissue specificity:Widely expressed. Expressed at high level in the thymus. Expressed in fetal and adult brain. Expressed in neurons, but not astrocytes. Markedly elevated in fetal as compared to adult brain. In the adult brain, expressed in the subventricular zone (SVZ), in hippocampus, and undetectable elsewhere. In the fetal brain, expressed in the germinal neuroepithelium and cortical plate regions., |
