RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC TISSUE=Kidney;
RG The German cDNA consortium;
RL Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Essential for the formation of P-bodies, cytosolic membrane-
CC less ribonucleoprotein granules involved in RNA metabolism through the
CC coordinated storage of mRNAs encoding regulatory functions. Plays a
CC role in P-bodies to coordinate the storage of translationally inactive
CC mRNAs in the cytoplasm and prevent their degradation. In the process of
CC mRNA degradation, plays a role in mRNA decapping. Blocks autophagy in
CC nutrient-rich conditions by repressing the expression of ATG-related
CC genes through degradation of their transcripts.
CC {ECO:0000250|UniProtKB:P26196}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13;
CC Evidence={ECO:0000250|UniProtKB:P26196};
CC -!- SUBUNIT: Interacts with LSM14A, LSM14B, EIF4ENIF1/4E-T, PATL1, EDC3 and
CC EDC4 (By similarity). Forms a complex with DCP1A, DCP2, EDC3 and
CC EDC4/HEDLS. Interacts with LIMD1, WTIP and AJUBA. Interacts with
CC APOBEC3G in an RNA-dependent manner (By similarity). Interacts with
CC RC3H1 (By similarity). Interacts with ATXN2L. Interacts with MCRIP1.
CC Interacts with MCRIP2. Interacts with NUFIP2. Interacts with TRIM71
CC (via NHL repeats) in an RNA-dependent manner (By similarity).
CC {ECO:0000250|UniProtKB:P26196, ECO:0000250|UniProtKB:P54823}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, P-body {ECO:0000250|UniProtKB:P26196}.
CC Cytoplasm {ECO:0000250|UniProtKB:P26196}. Nucleus
CC {ECO:0000250|UniProtKB:P26196}. Note=Imported in the nucleus via
CC interaction with EIF4ENIF1/4E-T via a piggy-back mechanism. Upon
CC cellular stress, relocalizes to stress granules.
CC {ECO:0000250|UniProtKB:P26196}.
CC -!- PTM: Sumoylated. {ECO:0000250|UniProtKB:P26196}.
CC -!- SIMILARITY: Belongs to the DEAD box helicase family. DDX6/DHH1
CC subfamily. {ECO:0000305}.
