Function

RNA-binding factor that may recruits target transcripts to cytoplasmic protein-RNA complexes (mRNPs). This transcript 'caging' into mRNPs allows mRNA transport and transient storage. It also modulates the rate and location at which target transcripts encounter the translational apparatus and shields them from endonuclease attacks or microRNA-mediated degradation. Binds to the 3'-UTR of CD44 mRNA and stabilizes it, hence promotes cell adhesion and invadopodia formation (By similarity). Binds to beta- actin/ACTB and MYC transcripts (By similarity). Binds to the 5'- UTR of the insulin-like growth factor 2 (IGF2) mRNAs. {ECO:0000250, ECO:0000269PubMed:15753088}.

Subcellular Localization

Nucleus {ECO:0000269PubMed:11288142, ECO:0000269PubMed:12921532}. Cytoplasm {ECO:0000250}. Note=Found in lamellipodia of the leading edge, in the perinuclear region, and beneath the plasma membrane. The subcytoplasmic localization is cell specific and regulated by cell contact and growth. Localized at the connecting piece and the tail of the spermatozoa. In response to cellular stress, such as oxidative stress, recruited to stress granules. {ECO:0000250}.

Disease Associations

Tissue Specificity

Expressed in oocytes, spermatogonia and spermatocytes (at protein level). {ECO:0000269PubMed:10525192, ECO:0000269PubMed:12161597, ECO:0000269PubMed:16049158}.
