Figure 1From: Rules of engagement promote polarity in RNA traffickingMolecular interactions of hnRNP A2 in the A2 RNA trafficking pathway. Five different molecular partners of hnRNP A2 have been identified in the A2 RNA trafficking pathway – hnRNP A2 itself, transportin 1, A2RE RNA, TOG and hnRNP E1. Each step of the A2 RNA trafficking pathway is mediated by interaction of hnRNP A2 with a particular partner. Although interactions between hnRNP A2 and each partner are reversible, the overall pathway exhibits polarity.Back to article page
