Anti-Spp382 antibodies are protein reagents that detect specific antigens. The Spp382 antigen is another term for the human protein tuftelin interacting protein 11, encoded by the TFIP11 gene. The protein is known to be involved in pre-mRNA splicing, specifically in spliceosome disassembly during late-stage splicing events. Canonically, it has an amino acid length of 837 residues and a mass of 96.8 kilodaltons. Its subcellular localization is in the nucleus and cytoplasm. The Spp382 protein is a member of the TFP11/STIP protein family. Other alias names for Spp382 include NTR1, NTR1, and STIP.
