General annotation (Comments)

Function

RNA-binding protein required for the microtubule-dependent transport of neuronal RNA from the cell body to the dendrite. As protein synthesis occurs within the dendrite, the localization of specific mRNAs to dendrites may be a prerequisite for neurite outgrowth and plasticity at sites distant from the cell body By similarity.

Subunit structure

Interacts with the exportin XPO5. This requires RNA and RAN bound to GTP. Interacts with microtubules. Isoform 2 and isoform 3 may also interact with ribosomes, and this association is independent of translation By similarity. Identified in a mRNP complex, at least composed of DHX9, DDX3X, ELAVL1, HNRNPU, IGF2BP1, ILF3, PABPC1, PCBP2, PTBP2, STAU1, STAU2, SYNCRIP and YBX1.

Subcellular location

Cytoplasm. Nucleus. Nucleusnucleolus. Endoplasmic reticulum. Note: Shuttles between the nucleolus, nucleus and the cytoplasm. Nuclear export of isoform 1 is independent of XPO1/CRM1 and requires the exportin XPO5. Nuclear export of isoform 2 and isoform 3 can occur by both XPO1/CRM1-dependent and XPO1/CRM1-independent pathways. Found in large cytoplasmic ribonucleoprotein (RNP) granules which are present in the actin rich regions of myelinating processes and associated with microtubules, polysomes and the endoplasmic reticulum. Also recruited to stress granules (SGs) upon inhibition of translation or oxidative stress. These structures are thought to harbor housekeeping mRNAs when translation is aborted By similarity.

Domain

The DRBM 3 domain appears to be the major RNA-binding determinant. This domain also mediates interaction with XPO5 and is required for XPO1/CRM1-independent nuclear export By similarity.

Sequence similarities

Contains 4 DRBM (double-stranded RNA-binding) domains.

Sequence caution

The sequence BAA91766.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.

The sequence BAB14522.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
