M6A methylation inhibits recruitment of the Dand5 3’UTR to the left-right determinant Bicc1

Daniel Constam, Benjamin Marcel Daniel Rothé, Simon Fortier

In vertebrates, left-right (LR) asymmetry is specified by asymmetric decay of Dand5 messenger RNA (mRNA) mediated by the recruitment of the BicC family RNA binding protein 1 (Bicc1). Besides regulating organ laterality, Bicc1 is required to prevent cystic ...

Bicc1 ribonucleoprotein complexes specifying organ laterality are licensed by ANKS6-induced structural remodeling of associated ANKS3

Matteo Dal Peraro, Daniel Constam, Benjamin Marcel Daniel Rothé, Simon Fortier, Zhidian Zhang

Organ laterality of vertebrates is specified by accelerated asymmetric decay of Dand5 mRNA mediated by Bicaudal-C1 (Bicc1) on the left side, but whether binding of this or any other mRNA to Bicc1 can be regulated is unknown. Here, we found that a CRISPR-en ...

Antagonistic interactions among structured domains in the multivalent Bicc1-ANKS3-ANKS6 protein network govern phase transitioning of target mRNAs

Daniel Constam, Benjamin Marcel Daniel Rothé, Simon Fortier, Céline Gagnieux, Céline Emmanuelle Schmuziger

The growing number of diseases linked to aberrant phase transitioning of ribonucleoproteins highlights the need to uncover how the interplay between multivalent protein and RNA interactions is regulated. Cytoplasmic granules of the RNA binding protein Bica ...
