Anti-INT9 antibodies enable researchers to detect and measure the INT9 antigen in biological samples. This target is a reported synonym of the INTS9 gene, which encodes integrator complex subunit 9. This protein is a known component of the Integrator (INT) complex, a complex involved in the small nuclear RNAs (snRNA) U1 and U2 transcription and in their 3'-box-dependent processing. The human version of INT9 has a canonical amino acid length of 658 residues and a protein mass of 73.8 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells. INT9 is a member of the RNA-metabolizing metallo-beta-lactamase-like protein family.
