THOC6 Antibody, FITC conjugated

What is THOC6 and what cellular functions does it perform?

THOC6 (THO Complex Subunit 6 homolog) is a component of the THO subcomplex within the TREX (transcription/export) complex. It plays a critical role in coupling mRNA transcription, processing, and nuclear export. THOC6 functions to tether TREX dimers to form tetramers that permit interaction with auxiliary molecules such as ALYREF and CHTOP . Through its WD40 domains, THOC6 interacts with THOC5 to facilitate tetramerization, which is essential for proper TREX complex function . Notably, THOC6 is positioned at the TREX core interface, directly heterodimerizing and homodimerizing with THOC5 and THOC6, respectively . Beyond its role in mRNA processing, THOC6 has been implicated in negative control of apoptosis involved in brain development, highlighting its importance in neural tissue development .

How are THOC6 FITC-conjugated antibodies typically characterized?

THOC6 FITC-conjugated antibodies undergo rigorous characterization to ensure specificity and functionality. These antibodies are typically tested in multiple applications including Western blot, immunoprecipitation, and immunohistochemistry across various cell lines and tissue samples . For example, THOC6 antibodies have demonstrated positive Western blot detection in A431 cells, mouse ovary tissue, and Neuro-2a cells . Immunoprecipitation validation is often performed in cell lines such as A431 cells, while immunohistochemistry testing may utilize tissues like human ovary tumor samples . Antibody purity is assessed through methods like protein G chromatography, with high-quality antibodies typically achieving >95% purity . The reactivity profile is established against target species (commonly human, mouse, and rat), and epitope mapping identifies the specific amino acid sequences recognized by the antibody, such as amino acids 56-315 of human THOC6 .
