background:
FYTTD1 is a 318 amino acid protein belonging to the UIF family. FYTTD1 localizes to nucleus and is required for mRNA export from nucleus to cytoplasm. Functioning as an adaptor, FYTTD1 utilizes the BAT1/DDX39-TAP pathway, which is essential for efficient mRNA export and nuclear pore delivery. FYTTD1 interacts with SSRP1, a protein that is necessary for its recruitment of mRNAs, in addition to a mutually exclusive interaction with BAT1/DDX39 and TAP. FYTTD1 exists as four alternatively spliced isoforms and is encoded by a gene located on human chromosome 3q29.
Function:
Required for mRNA export from the nucleus to the cytoplasm. Acts as an adapter that uses the DDX39B/UAP56-NFX1 pathway to ensure efficient mRNA export and delivering to the nuclear pore. Associates with spliced and unspliced mRNAs simultaneously with THOC4.
Subunit:
Interacts with CHTOP (By similarity). Interacts with DDX39B/UAP56 and NXF1; interaction with DDX39B/UAP56 and NXF1 are mutually exclusive. Interacts with SSRP1; required for its recruitment to mRNAs.
Subcellular Location:
Nucleus; nucleoplasm. Nucleus speckle.
Similarity:
Belongs to the UIF family.
