Organism:
Mouse (Mus musculus).
General Annotation
Sub Unit:
Component of the coding region determinant (CRD)-mediated complex, composed of DHX9, HNRNPU, IGF2BP1, SYNCRIP and YBX1. Identified in a mRNP complex, at least composed of DHX9, DDX3X, ELAVL1, HNRNPU, IGF2BP1, ILF3, PABPC1, PCBP2, PTBP2, STAU1, STAU2, SYNCRIP and YBX1. Identified in a mRNP granule complex, at least composed of ACTB, ACTN4, DHX9, ERG, HNRNPA1, HNRNPA2B1, HNRNPAB, HNRNPD, HNRNPL, HNRNPR, HNRNPU, HSPA1, HSPA8, IGF2BP1, ILF2, ILF3, NCBP1, NCL, PABPC1, PABPC4, PABPN1, RPLP0, RPS3, RPS3A, RPS4X, RPS8, RPS9, SYNCRIP, TROVE2, YBX1 and untranslated mRNAs. Interacts with IGF2BP1. Binds MBD2, HRMT1L2/PRMT1, and RELA. May act to directly link BRCA1, CREBBP or SMN1 and the RNA polymerase II complex. Can also interact with XRCC5 and with TOP2A in an RNA dependent manner; these interactions may be indirect. Interaction with TOP2A is promoted by UBC9. Interacts with histone H2AFX and this requires phosphorylation of H2AFX on 'Ser-139' (By similarity). Interacts with ZIC2.
Function:
Component of the CRD-mediated complex that promotes MYC mRNA stability. Unwinds double-stranded DNA and RNA in a 3' to 5' direction. Alterations of secondary structure may subsequently influence interactions with proteins or other nucleic acids. Functions as a transcriptional activator.
Subcellular Location:
Nucleus
nucleolus
Cytoplasm
Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Can shuttle between nucleus and cytoplasm.
