High impact information on PUF4

  • Furthermore, this relocalization is dependent on both UTH4 a novel yeast gene that extends life span, and its homologue YGL023 [1].
  • We identified and computationally characterized the binding sites for six mRNA stability regulators in Saccharomyces cerevisiae, which include two members of the Pumilio-homology domain (Puf) family of RNA-binding proteins, Puf3p and Puf4p [2].
  • Pan2p and Puf4p also contributed to the degradation rate of these mRNAs following transcriptional shutoff, while Pub1p preferentially stabilized transcripts encoding ribosomal proteins [3].
  • Deletions in SSD1 and PUF4, potential alternative regulators of cell integrity, also exhibit phenotypes [4].
  • Thus, these Ime4 and Puf4 proteins play complementary roles to rescue the defects in Deltampt5 Deltasir cells [5].
 

Associations of PUF4 with chemical compounds

  • Furthermore, the suppression of the HU sensitivity depended on PUF4, another Puf-family gene, and overexpression of PUF4 suppressed only the HU sensitivity of Deltampt5 [5].
 

Other interactions of PUF4

  • We identified distinct sequence motifs in the 3'-untranslated regions of the mRNAs bound by Puf3p, Puf4p, and Puf5p [6].
