PSIP1 polyclonal antibody

The lens epithelium-derived growth factor (LEDGF), also designated p75p52, is a transcriptional coactivator that complexes with the human immunodeficiency virus type 1 (HIV-1) integrase. LEDGF/p75p52 is essential for the nuclear localization and chromosomal association of viral proteins. As the primary integrase-to-chromatin tethering factor for HIV-1, LEDGF/p75p52 is responsible for the cellular trafficking of lentiviral integrases. During apoptosis, LEDGF/p75p52 is cleaved at three sites by caspase-3 and caspase-7, contributing to the pathogenesis of atopic disorders.
