Supplementary information

Pumilio 1 also known as PUM1 is a human protein coding for RNA-binding protein involved in the translational regulation of mRNA. It has a molecular weight of approximately 120 kDa. PUM1 expresses in various tissues with higher concentrations in brain placenta and testis. This protein contains a distinct Pumilio Homology Domain which allows it to specifically recognize and bind to a conserved sequence motif known as Pumilio Response Element (PRE) in target mRNAs.
Biological function summary

PUM1 is an important regulator of gene expression. It functions by binding to the 3' untranslated regions of target mRNAs leading to repression of translation and in some cases RNA decay. PUM1 operates within larger ribonucleoprotein complexes collaborating with other regulatory proteins to fine-tune the stability and translation of specific transcripts. This regulation is vital for processes like neuronal development stem cell maintenance and germ cell development.

Pathways

The influence of PUM1 extends to key biological networks such as the cell cycle and long-term potentiation pathways. It interacts with proteins like DDX6 which synergize to mediate post-transcriptional regulation as part of the mRNA decay pathway. Through its role in these pathways PUM1 helps ensure precise control of gene expression necessary for cellular homeostasis and adaptive responses to environmental changes.

The dysfunction of PUM1 is linked to neurological and reproductive conditions. Mutations or alterations in PUM1 expression have associations with spinocerebellar ataxia and gonadal dysgenesis. In these contexts PUM1 aberrations may also involve interactions with proteins such as FMRP known for its roles in neurological development and reproductive processes pointing to a complex network of genetic regulation and disease manifestation.

Target data

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 : 18328718, PubMed : 21397187, PubMed : 21572425, PubMed : 21653694). 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 (PubMed : 22955276). Also mediates deadenylation-independent repression by promoting accessibility of miRNAs (PubMed : 18776931, PubMed : 20818387, PubMed : 20860814, PubMed : 22345517). Following growth factor stimulation, phosphorylated and binds to the 3'-UTR of CDKN1B/p27 mRNA, inducing a local conformational change that exposes miRNA-binding sites, promoting association of miR-221 and miR-222, efficient suppression of CDKN1B/p27 expression, and rapid entry to the cell cycle (PubMed : 20818387). Acts as a post-transcriptional repressor of E2F3 mRNAs by binding to its 3'-UTR and facilitating miRNA regulation (PubMed : 22345517, PubMed : 29474920). 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 (PubMed : 26724866). Involved in neuronal functions by regulating ATXN1 mRNA levels : acts by binding to the 3'-UTR of ATXN1 transcripts, leading to their down-regulation independently of the miRNA machinery (PubMed : 25768905, PubMed : 29474920). Plays a role in cytoplasmic sensing of viral infection (PubMed : 25340845). In testis, acts as a post-transcriptional regulator of spermatogenesis by binding to the 3'-UTR of mRNAs coding for regulators of p53/TP53. Involved in embryonic stem cell renewal by facilitating the exit from the ground state : acts by targeting mRNAs coding for naive pluripotency transcription factors and accelerates their down-regulation at the onset of differentiation (By similarity). Binds specifically to miRNA MIR199A precursor, with PUM2, regulates miRNA MIR199A expression at a postranscriptional level (PubMed : 28431233).
