Anti-INTS11 antibodies are used in the immunodetection of the protein integrator complex subunit 11. In humans, the canonical protein has a reported length of 600 amino acid residues and a mass of 67.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 5 different isoforms for this protein. A member of a the RNA-metabolizing metallo-beta-lactamase-like protein family, INTS11 is reported to be a catalytic 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. Synonyms for this target antigen include CPSF73L, INT11, RC-68, RC68, CPSF3-like protein, and CPSF3L.
