RNA-binding factor that 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. Regulates localized beta-actin/ACTB mRNA translation, a crucial process for cell polarity, cell migration and neurite outgrowth. Co-transcriptionally associates with the ACTB mRNA in the nucleus. This binding involves a conserved 54-nucleotide element in the ACTB mRNA 3'-UTR, known as the 'zipcode'. The RNP thus formed is exported to the cytoplasm, binds to a motor protein and is transported along the cytoskeleton to the cell periphery. During transport, prevents ACTB mRNA from being translated into protein. When the RNP complex reaches its destination near the plasma membrane, IGF2BP1 is phosphorylated. This releases the mRNA, allowing ribosomal 40S and 60S subunits to assemble and initiate ACTB protein synthesis. Monomeric ACTB then assembles into the subcortical actin cytoskeleton (By similarity).

During neuronal development, key regulator of neurite outgrowth, growth cone guidance and neuronal cell migration, presumably through the spatiotemporal fine tuning of protein synthesis, such as that of ACTB (By similarity).

May regulate mRNA transport to activated synapses (By similarity).

Binds to the 3'-UTR of CD44 mRNA and stabilizes it, hence promotes cell adhesion and invadopodia formation in cancer cells (By similarity).

Binds to the oncofetal H19 transcript and regulates its localization (By similarity).

Binds to and stabilizes BTRC/FBW1A mRNA (By similarity).

Binds to the adenine-rich autoregulatory sequence (ARS) located in PABPC1 mRNA and represses its translation. PABPC1 mRNA-binding is stimulated by PABPC1 protein. Prevents BTRC/FBW1A mRNA degradation by disrupting microRNA-dependent interaction with AGO2 (By similarity).

During cellular stress, such as oxidative stress or heat shock, stabilizes target mRNAs that are recruited to stress granules, including CD44, IGF2, MAPK4, MYC, PTEN, RAPGEF2 and RPS6KA5 transcripts (By similarity).

Interacts with GAP43 transcript and transports it to axons. Binds to the 3'-UTR of IGF2 mRNA by a mechanism of cooperative and sequential dimerization and regulates IGF2 mRNA subcellular localization and translation. Binds to MYC mRNA, in the coding region instability determinant (CRD) of the open reading frame (ORF), hence prevents MYC cleavage by endonucleases and possibly microRNA targeting to MYC-CRD. Binds to and stabilizes ABCB1/MDR-1 mRNA. Binds to the neuron-specific TAU mRNA and regulates its localization. Plays a direct role in the transport and translation of transcripts required for axonal regeneration in adult sensory neurons. During interstinal wound repair, interacts with and stabilizes PTGS2 transcript. PTGS2 mRNA stabilization may be crucial for colonic mucosal wound healing.

Mutant mice exhibit high perinatal mortality and only 50% are alive 3 days after birth. Early death may be due to intestinal dysfunction. Animals are on average 40% smaller than wild-type and heterozygous sex-matched littermates. Growth retardation, probably due to hypoplasia, appears from 17.5 dpc and remains permanent into adult life. Mutant animals exhibit other stricking features, including impaired development of the intestine, with small and misshapen villi and twisted colon crypts, abnormal kidney architecture and loss of cartilage in the lower extremities. Some animals show signs of neurological damage, including aggressive behavior, restlessness and circular movements.1 Publication

Expressed during embryonic development and expression declines towards birth (at protein level). At 10.5 dpc, mainly expressed in the fore- and hindbrain, the snout, the branchial arches, the developing limb buds, and the tail. At 12.5 dpc, expression increased in the expanding fore- and hindbrain, as well as in the neural tract. Marked expression also observed in the snout, the interdigital mesenchyme of the limb buds, the tail, the branchial arches and somites, and the developing eye, tongue, heart and liver. Expressed in myoblasts and myotubes at 12.5 dpc (at protein level). From 12.5 to 15.5 dpc, expressed at the basal plasma cell membrane in the basal layer of the epidermis of the skin, lung and intestine (at protein level). Expressed in gonads at 12.5 and 14.5 dpc (at protein level). At 14.5 dpc in limb buds, becomes restricted to the future tendons. Expressed in germ cells at 16.5 dpc (at protein level). At 17.5 dpc, expression generally decreases, but remains high in the intestine, in the developing tubules of the kidney, and in the liver. Expressed until P12, although very low levels may remain in some tissues, such as intestines, kidney and brain, throughout adulthood. Following colonic injury, up-regulated in the wound mucosa at days 2 and 4 post-injury and down-regulated at day 6 post-injury, as compared with uninjured mucosa.6 Publications

<p>This subsection of the 'Family and domains' section provides general information on the biological role of a domain. The term 'domain' is intended here in its wide acceptation, it may be a structural domain, a transmembrane region or a functional domain. Several domains are described in this subsection.<p><a href='/help/domain_cc' target='_top'>More...</a></p>Domaini

Domain KH3 and KH4 are the major RNA-binding modules, although KH1 and KH2 may also contribute. KH1 and KH2, and possibly KH3 and KH4, promote the formation of higher ordered protein-RNA complexes, which may be essential for IGF2BP1 cytoplasmic retention. KH domains are required for RNA-dependent homo- and heterooligomerization and for localization to stress granules. KH3 and KH4 mediate association with the cytoskeleton. Two nuclear export signals (NES) have been identified in KH2 and KH4 domains, respectively. Only KH2 NES is XPO1-dependent. Both NES may be redundant, since individual in vitro mutations do not affect subcellular location of the full-length protein.

<p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: O88477
Secondary accession number(s): Q80US9, Q8BRH1
<p>This subsection of the 'Entry information' section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification ('Last modified'). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical%5Fand%5Fisoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: April 3, 2007
