Target Background

Function

Sequence-specific RNA-binding protein that acts as a post-transcriptional repressor by binding the 3'-UTR of mRNA targets. Binds to an RNA consensus sequence, the Pumilio Response Element (PRE), 5'-UGUANAUA-3', that is related to the Nanos Response Element (NRE) (, PubMed:21397187). Mediates post-transcriptional repression of transcripts via different mechanisms: acts via direct recruitment of the CCR4-POP2-NOT deadenylase leading to translational inhibition and mRNA degradation. Also mediates deadenylation-independent repression by promoting accessibility of miRNAs. Acts as a post-transcriptional repressor of E2F3 mRNAs by binding to its 3'-UTR and facilitating miRNA regulation. Plays a role in cytoplasmic sensing of viral infection. Represses a program of genes necessary to maintain genomic stability such as key mitotic, DNA repair and DNA replication factors. Its ability to repress those target mRNAs is regulated by the lncRNA NORAD (non-coding RNA activated by DNA damage) which, due to its high abundance and multitude of PUMILIO binding sites, is able to sequester a significant fraction of PUM1 and PUM2 in the cytoplasm. May regulate DCUN1D3 mRNA levels. May support proliferation and self-renewal of stem cells. Binds specifically to miRNA MIR199A precursor, with PUM1, regulates miRNA MIR199A expression at a postranscriptional level.

results reveal a novel regulatory pathway, underscoring a previously unknown and interconnected key role of PUM1/2 and FOXP1 in regulating normal hematopoietic stem/progenitor cell and leukemic cell growth. PMID: 28232582
The study shows that pseudouridine and N(6)-methyladenosine weaken the binding of the human single-stranded RNA binding protein Pumilio 2 (hPUM2) to its consensus motif. PMID: 28138061
Pumilios (including PUM1 and PUM2) are RNA-binding proteins with Puf domains made up of 8 poorly conserved Puf repeats, 3 helix bundles arranged in rainbow architecture, where each repeat recognizes a single base of the RNA-binding sequence. [REVIEW] PMID: 26517885
Identification of NORAD-interacting proteins revealed that this lncRNA functions as a multivalent binding platform for PUM proteins, with the capacity to sequester a significant fraction of the total cellular pool of PUM1 and PUM2. Studies reveal unanticipated roles for a lncRNA and PUMILIO proteins in the maintenance of genomic stability. PMID: 26724866
PUM2 does not repress differentiation of adipose-derived stem cells (ASCs) but rather is involved in the positive control of ASCs division and proliferation. PMID: 21649561
human Pumilio homologs Pum 1 and Pum 2 repress the translation of E2F3 by binding to the E2F3 3' untranslated region (UTR) and also enhance the activity of multiple E2F3 targeting microRNAs (miRNAs) PMID: 22345517

PUMILIO mediated translational regulation may be universally used in developmental processes of the human body. PMID: 16967088
Variation in the PUMILIO2 gene is very low and it seems improbable that mutations of this gene significantly contribute to male infertility in humans. PMID: 17154300
Data found that PUMILIO2 interacts also with SNAPIN, a modulator of SNARE complex assembly, which is involved in vesicle trafficking. PMID: 19168546
