These Vpr (HIV-1) binding protein ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Vpr (HIV-1) binding protein is an alias of the human DCAF1 gene, which encodes the protein, DDB1 and CUL4 associated factor 1. Notably, Vpr (HIV-1) binding protein is known to play a role in B cell differentiation and chromatin organization, among other functions. The DCAF1 protein is 1507 amino acid residues in length and 169 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. Other names for this target antigen include RIP, VPRBP, and HIV-1 Vpr-binding protein.
