FUNCTION

PC4 and SFRS1 interacting protein 1, also known as lens epithelium-derived growth factor (LEDGF/p75), dense fine speckles 70kD protein (DFS 70) or transcriptional coactivator p75/p52, is a protein that in humans is encoded by the PSIP1 gene. PSIP1 has not been clearly linked to a specific cellular mechanism. The term LEDGF/p75 (Lens epithelium-derived growth factor) has entered common usage based on the initial characterization of PSIP1, however this is a misnomer, as the protein is present in most tissues and has no direct role in the development of lens epithelium. LEDGF/p75, a transcription coactivator, gained prominence as a host factor that assists HIV integration and is probably the only integrase interactor whose knock-down severely affects the HIV integration levels. The interaction between HIV integrase and human LEDGF/p75 is a promising target for anti-HIV drug discovery. LEDGF/p75 recruits MLL complexes to HOX genes to regulate their expression. LEDGF/p52 is shown to recruit splicing factors to H3K36 trimethylated chromatin to modulate alternative splicing, also regulates HOTTIP lncRNA, which is shown to regulate HOX genes in cis.
