CC -!- FUNCTION: Required for efficient export of polyadenylated RNA and
CC spliced mRNA. Acts as component of the THO subcomplex of the TREX
CC complex which is thought to couple mRNA transcription, processing and
CC nuclear export, and which specifically associates with spliced mRNA and
CC not with unspliced pre-mRNA. TREX is recruited to spliced mRNAs by a
CC transcription-independent mechanism, binds to mRNA upstream of the
CC exon-junction complex (EJC) and is recruited in a splicing- and cap-
CC dependent manner to a region near the 5' end of the mRNA where it
CC functions in mRNA export to the cytoplasm via the TAP/NFX1 pathway.
CC Plays a role for proper neuronal development.
CC {ECO:0000250|UniProtKB:Q8NI27}.
CC -!- SUBUNIT: Component of the THO complex, which is composed of THOC1,
CC THOC2, THOC3, THOC5, THOC6 and THOC7; together with at least
CC ALYREF/THOC4, DDX39B, SARNP/CIP29 and CHTOP, THO forms the
CC transcription/export (TREX) complex which seems to have a dynamic
CC structure involving ATP-dependent remodeling. Interacts with THOC1,
CC POLDIP3 and ZC3H11A (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}. Nucleus speckle
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the THOC2 family. {ECO:0000305}.
