Members of this family adopt a structure consisting of a small globular all-beta-domain, with a three-stranded beta-sheet and a contiguous beta-hairpin. They bind to Mago alpha-helices via extensive electrostatic interactions and at a beta2-beta3 loop via hydrophobic interactions [1].


Partner of Y14 and mago (PYM, also known as WIBG) is a key regulator of the exon junction complex (EJC), a multiprotein complex that associates immediately upstream of the exon-exon junction on mRNAs and serves as a positional landmarks for the intron exon structure of genes and directs post-transcriptional processes in the cytoplasm such as mRNA export, nonsense-mediated mRNA decay (NMD) or translation [PUBMED:18026120, PUBMED:19410547].
