MetabolomicsSCP4-STK35/PDIK1L complex is a dual phospho-catalytic signaling dependency in acute myeloid leukemia
Acute myeloid leukemia (AML) cells rely on phospho-signaling pathways to gain unlimited proliferation potential. Here, we used domain-focused CRISPR screening to identify the nuclear phosphatase SCP4 as a dependency in AML, yet this enzyme is dispensable in normal hematopoietic progenitor cells. Usi...

TranscriptomicsA novel miRNA processing pathway independent of Dicer requires Argonaute2 catalytic activity
Here we identify a Dicer-independent miRNA biogenesis pathway that employs the slicer catalytic activity of Argonaute2 (Ago2). To uncover Dicer-independent miRNAs, we sequenced small RNAs in wild type, maternal-zygotic dicer (MZdicer) and MZago2 mutants, using zebrafish as a model system. We find t...

ProteomicsCrosslinking mass spectrometry of the p300 catalytic core complexed with the nucleosome
p300 is a histone acetyltransferase that associates with crucial biological processes. p300 acetylates all four histones in the nucleosome, a basic unit of chromatin, and alters chromatin structure and dynamics. In this study, we performed structural and biochemical analysis to understand the nucleo...

TranscriptomicsTranscription profiling of primary human CD4+T-cells overexpressing TET1 polarized towards Th1
Differentiation of CD4+T-cells into effector subsets is a critical component of the adaptive immune system and an incorrect response can lead to autoimmunity or immune deficiency. Cellular differentiation including T-cell differentiation is accompanied by large-scale epigenetic remodeling, including...

TranscriptomicsSlicing-Independent RISC Activation Requires the Argonaute PAZ Domain
Small RNAs regulate the genetic networks through a ribonucleoprotein complex called the RNA induced silencing complexes (RISC), which in mammals contains at its center one of four Argonaute proteins (Ago1-4). A key regulatory event in the RNAi and miRNA pathways is Ago loading, where double stranded...

ProteomicsTargeted stress granule regulation by engineering a non-catalytic O-GlcNAc transferase
Stress granules (SGs) are dynamic ribonucleoprotein condensates whose assembly is driven by multivalent interactions and liquid-liquid phase separation (LLPS) of their component proteins and mRNAs. Related to multiple diseases, SGs are an ideal prototype to study cellular condensates. Understanding ...

TranscriptomicsPrp8 Retinitis Pigmentosa Mutants Cause Defects in the Transition between the Catalytic Steps of Splicing
The essential process of pre-mRNA splicing must occur with high fidelity and efficiency for proper gene expression. The spliceosome employs DExD/H box helicases to promote on-pathway interactions while simultaneously minimizing errors. Prp8 and Snu114, an EF2-like GTPase, regulate the activity of th...

ProteomicsCullin-independent recognition of HHARI substrates by a dynamic RBR catalytic domain
RING-Between-RING (RBR) E3 ligases mediate ubiquitin transfer through an obligate E3- ubiquitin thioester intermediately prior to substrate ubiquitination. While RBRs share a conserved catalytic module, substrate recruitment mechanisms remain enigmatic and the relevant domains have yet to be identi...
