Another decapping activator PatL1 directly interacts with CIR and alleviates the CIR-mediated inhibition of CCR4-NOT activity in vitro. Ribosome profiling revealed that XRN1 loss impacts not only on mRNA levels but also on the translational efficiency of many cellular transcripts likely as a consequence of incomplete decay
Title: A low-complexity region in human XRN1 directly recruits deadenylation and decapping factors in 5'-3' messenger RNA decay.
evidence for a nuclear complex of Pat1b with the Lsm2-8 heptamer, which binds to the spliceosomal U6 small nuclear RNA (snRNA).
Title: Dual RNA Processing Roles of Pat1b via Cytoplasmic Lsm1-7 and Nuclear Lsm2-8 Complexes.
data indicate that P-body assembly occurs in a step-wise manner, where Rck participates in the initial suppression of mRNA translation, whereas Pat1b in a second step triggers P-body assembly and promotes mRNA decapping
Title: Role of Rck-Pat1b binding in assembly of processing-bodies.
The PATL1 as well as DCP1A, a well-known P-body marker, co-localized with a subset of ALG-2.
Title: Identification of the P-body component PATL1 as a novel ALG-2-interacting protein by in silico and far-Western screening of proline-rich proteins.
Pat1b participates in several RNA-related nuclear processes in addition to its multiple regulatory roles in the cytoplasm
Title: RNA-related nuclear functions of human Pat1b, the P-body mRNA decay factor.
Pat1b represses gene expression by inducing deadenylation of the mRNAs.
Title: The human Pat1b protein: a novel mRNA deadenylation factor identified by a new immunoprecipitation technique.
hPat1b localizes to P-bodies, while mPat1a-GFP is either found weakly in P-bodies or disperses P-bodies in a dominant-negative fashion.
Title: Distinct functions of maternal and somatic Pat1 protein paralogs.
By tethering Pat1b to a reporter mRNA, the study provides evidence that Pat1b is also functionally linked to both deadenylation and decapping.
Title: Human Pat1b connects deadenylation with mRNA decapping and controls the assembly of processing bodies.
Data show that PatL1 is essential for the interaction with mRNA decapping factors (i.e. DCP2, EDC4 and LSm1-7), whereas the P-rich region and Mid domain have distinct functions in modulating these interactions.
Title: The C-terminal alpha-alpha superhelix of Pat is required for mRNA decapping in metazoa.
The identification of two human PAT1 genes is described and one of them, PATL1, codes for an open reading frame with similar features as the yeast PAT1.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
