Background

Function
ILF3 is a RNA-binding protein that plays an essential role in the biogenesis of circular RNAs (circRNAs) which are produced by back-splicing circularization of pre-mRNAs. Within the nucleus, promotes circRNAs processing by stabilizing the regulatory elements residing in the flanking introns of the circularized exons. Plays thereby a role in the back-splicing of a subset of circRNAs. As a consequence, participates in a wide range of transcriptional and post-transcriptional processes. Binds to poly-U elements and AU-rich elements (AREs) in the 3'-UTR of target mRNAs. Upon viral infection, ILF3 accumulates in the cytoplasm and participates in the innate antiviral response. Mechanistically, ILF3 becomes phosphorylated and activated by the double-stranded RNA-activated protein kinase/PKR which releases ILF3 from cellular mature circRNAs. In turn, unbound ILF3 molecules are able to interact with and thus inhibit viral mRNAs; (Microbial infection) Plays a positive role in HIV-1 virus production by binding to and thereby stabilizing HIV-1 RNA, together with ILF3[1][2][3][4].

Q12906 has 7 isomers: Q12906-1: 95338 Da (predicted); Q12906-2: 76033 Da (predicted); Q12906-3: 82802 Da (predicted); Q12906-4: 75508 Da (predicted); Q12906-5: 74607 Da (predicted); Q12906-6: 76502 Da (predicted); Q12906-7: 95808 Da (predicted).
Phosphorylated at Thr-188 and Thr-315 by PKR in response to certain RNA viruses. This phosphorylation results in the dissociation of ILF2 from the ILF2-ILF3 complex resulting in a cytoplasmic sequestration of ILF3 where it can bind to viral RNAs and impede viral replication;Methylated by protein arginine N-methyltransferase 1;Ubiquitinated at Lys-297 in a TRIM47-dependent manner; this 'Lys-48'-linked ubiquitination promotes ILF3 degradation -
Subunit
Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs. Interacts with FUS and SMN. Interacts (via C-terminus) with PRMT1. Forms a complex with ILF2. Can also bind to PRKDC/XRCC7: this may stabilize the interaction of PRKDC/XRCC7 and the heterodimeric complex of XRCC6/KU70 and XRCC5/KU80. Forms a heteromeric complex with ZNF346 and ILF3. Found in a nuclear export complex with XPO5, ILF3, Ran and double-stranded RNA or double-stranded minihelix VA1 RNA. Found in a nuclear export complex with XPO5, RAN, ILF3, ZNF346 and double-stranded RNA. Interacts with XPO5 and ZNF346. Forms a complex with ILF2, YLPM1, KHDRBS1, RBMX, NCOA5 and PPP1CA. Interacts with AGO1 and AGO2. Interacts with DHX36; this interaction occurs in a RNA-dependent manner (PubMed:14731398). Interacts with ELAVL1; this interaction occurs in a RNA-dependent manner (PubMed:14731398). Interacts with HAVCR2; this interaction promotes ILF3 ubiquitination and subsequent degradation (PubMed:34110282)
