This domain is found in Psi proteins produced by Drosophila, and in various eukaryotic hypothetical proteins. It has no known function.
This entry represents a domain found in the C terminus of Far upstream element-binding protein 1/2 (FUBP1/2) [PUBMED:8940189]. FUBP1 regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter [PUBMED:8125259, PUBMED:28076379]. FUBP2, also known as KSRP (K homology-type splicing regulatory protein), is an single-strand-RNA binding protein that integrate different levels of gene expression and is required for proper immune response, lipid metabolism, cell fate decisions, and tissue regeneration [PUBMED:24845017].
