Background
The product of this gene is a core component of the exon junction complex (EJC), a protein complex that is deposited on spliced mRNAs at exon-exon junctions and functions in nonsense-mediated mRNA decay (NMD). The encoded protein binds RNA and interacts with two other EJC core components. It is predominantly located in the cytoplasm, but shuttles into the nucleus where it localizes to nuclear speckles.

Function
domain:The coiled coil domain may be involved in oligomerization.,function:Component of the dendritic ribonucleoprotein particles (RNPs) in hippocampal neurons. May play a role in mRNA transport.,PTM:Phosphorylated.,subcellular location:Predominantly found in the perinuclear region (By similarity). Shuttles between the nucleus and the cytoplasm in a CRM1-dependent manner.,subunit:Interacts with STAU in an RNA-dependent manner (By similarity). Forms homo-oligomers.,tissue specificity:Widely expressed. Overexpressed in breast cancers and metastasis, as well as in gastric cancers.,

Cellular localization
Cytoplasm . Cytoplasm, perinuclear region . Nucleus . Nucleus speckle . Cytoplasm, Stress granule . Cytoplasm, Cytoplasmic ribonucleoprotein granule . Cell projection, dendrite . Shuttles between the nucleus and the cytoplasm in a XPO1/CRM1-dependent manner. Transported to the cytoplasm as part of the exon junction complex (EJC) bound to mRNA (PubMed:15166247). In nuclear speckles, colocalizes with MAGOH. Under stress conditions, colocalizes with FMR1 and TIA1, but not MAGOH and RBM8A EJC core factors, in cytoplasmic stress granules (PubMed:17652158). In the dendrites of hippocampal neurons, localizes to dendritic ribonucleoprotein granules (By similarity). .
Tissue expression
Widely expressed. Overexpressed in breast cancers and metastasis, as well as in gastric cancers.
