Exclusive neuronal expression of SUCLA2 in the human brain [PDF]

, 2013
SUCLA2 encodes the ATP-forming subunit (A-SUCL-) of succinyl-CoA ligase, an enzyme of the citric acid cycle. Mutations in SUCLA2 lead to a mitochondrial disorder manifesting as encephalomyopathy with dystonia, deafness and lesions in the basal ganglia ...

Purification of wheat germ RNA ligase. II. Mechanism of action of wheat germ RNA ligase.

Journal of Biological Chemistry, 1986
The mechanism of action of purified wheat germ RNA ligase has been examined. ATP was absolutely required for the ligation of substrates containing 5'-OH or 5'-P and 2',3'-cyclic P or 2'-P termini. Ligation of 1 mol of 5'-P-2',3'-cyclic P-terminated poly(A) was accompanied by the hydrolysis of 1 mol of ATP to 1 mol each of AMP and PPi.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

FEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

FBXO2 Promotes Proliferation of Endometrial Cancer by Ubiquitin-Mediated Degradation of FBN1 in the Regulation of the Cell Cycle and the Autophagy Pathway

Frontiers in Cell and Developmental Biology, 2020
F-box proteins, as substrates for S phase kinase-associated protein 1 (SKP1)-cullin 1 (CUL1)-F-box protein (SCF) ubiquitin ligase complexes, mediate the degradation of a large number of regulatory proteins involved in cancer processes.

Structures of the noncanonical RNA ligase RtcB reveal the mechanism of histidine guanylylation.

Biochemistry, 2013
RtcB is an atypical RNA ligase that joins either 2',3'-cyclic phosphate or 3'-phosphate termini to 5'-hydroxyl termini. In contrast to typical RNA ligases, which rely on ATP and Mg(II), catalysis by RtcB is dependent on GTP and Mn(II) with ligation ...

Location of the adenylylation site in T4 RNA ligase [PDF]

European Journal of Biochemistry, 1985
The purification of the enzyme T4 RNA ligase is described from an Escherichia coli strain, KR 54, in which the RNA ligase gene (g63) has been inserted into the plasmid pDR540 for inducible expression of g63 from the tac promoter. Adenylylation of the purified enzyme with [14C]rATP followed by digestion with chymotrypsin yielded an adenylylated peptide,

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

Molecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

iRhom2 is essential for innate immunity to RNA virus by antagonizing ER- and mitochondria-associated degradation of VISA. [PDF]

PLoS Pathogens, 2017
VISA (also known as MAVS, IPS-1 and Cardif) is an essential adaptor protein in innate immune response to RNA virus. The protein level of VISA is delicately regulated before and after viral infection to ensure the optimal activation and timely termination

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

tRNA ligase structure reveals kinetic competition between non-conventional mRNA splicing and mRNA decay

eLife, 2019
Yeast tRNA ligase (Trl1) is an essential trifunctional enzyme that catalyzes exon-exon ligation during tRNA biogenesis and the non-conventional splicing of HAC1 mRNA during the unfolded protein response (UPR).
