Poly-adenylate binding protein, unique domain. The region featured in this family is found towards the C-terminus of poly(A)-binding proteins (PABPs). These are eukaryotic proteins that, through their binding of the 3' poly(A) tail on mRNA, have very important roles in the pathways of gene expression. They seem to provide a scaffold on which other proteins can bind and mediate processes such as export, translation and turnover of the transcripts. Moreover, they may act as antagonists to the binding of factors that allow mRNA degradation, regulating mRNA longevity. PABPs are also involved in nuclear transport. PABPs interact with poly(A) tails via RNA-recognition motifs (pfam00076). Note that the PABP C-terminal region is also found in members of the hyperplastic discs protein (HYD) family of ubiquitin ligases that contain HECT domains - these are also included in this family.
No pairwise interactions found for the domain PABP
Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:  No Conserved Features/Sites Found for PABP
