Such a form of “multifactor auyhorization” of course protects posttranscriptional regulatory pathways from aberrant expression of individual components - as we observed in the case of DND1/NANOS3: their ectopic expression sends any cell into cell-cycle arrest.

The specific motif built up by these two RBPs cannot be identified by studying each of them in isolation, so one important question we would like to raise is: How many RBPs form heteromultimeric complexes with specificity other than the sum of the individual RBPs?

This work was spearheaded by Masataka Suzawa in my (NIAMS) and Chen Qiu in Traci Hall’s lab (NIEHS IRP) and initiated together with Masashi Yamaji’s group at Cincinnati Children’s. Wonderful collaboration with @eugenevalkov.bsky.social and Vittorio Sartorelli.

Delighted to share the story of two germline RBPs - one with little (DND1) and one with no (NANOS3) intrinsic sequence-specificity - that together build a continuous RNA binding surface recognizing a 7-mer (AUGAAUU) in target mRNA 3’UTRs, leading to deadenylation.

Very excited that our most significant work, a collaboration w/ Dr. Can Cenik at UT Austin on translational gene regulation, was finally published in Nature Biotechnology in a dual set of studies:

Paper 1 -- an AI model trained to predict translation rates from mRNA sequences: rdcu.be/exN1l
Predicting the translation efficiency of messenger RNA in mammalian cells
Nature Biotechnology - A deep convolutional neural network model predicts the influence of the full-length mRNA sequence on translation efficiency.

Excited to finally be heading to RNA 2025 in San Diego! Have worked with amazing colleagues to co-organize this meeting so I can’t wait to see all the exciting science and connect with colleagues! @rnabiologist.bsky.social @kkarbstein.bsky.social

Rbm24a dictates mRNA recruitment for germ granule assembly in zebrafish
Yizhuang Zhang et al show that loss of maternal Rbm24a causes complete degradation of germ granules and disappearance of primordial germ cells

I am happy to share the latest paper from the lab. We detail a tripartite cell-free translation system based on the separation of mRNAs, ribosomes and ribosome-depleted cytoplasmic lysate from human cells, allowing for flexible reconstitution of translation reaction.
