Genetic variation in P-element dysgenic sterility is associated with double-strand break repair and alternative splicing of TE transcripts
(Public Library of Science, 2022-12-07)The germline mobilization of transposable elements (TEs) by small RNA mediated silencing pathways is conserved across eukaryotes and critical for ensuring the integrity of gamete genomes. However, genomes are recurrently ... -
QAUST: Protein Function Prediction Using Structure Similarity, Protein Interaction, and Functional Motifs
(Elsevier, 2021-02-23)The number of available protein sequences in public databases is increasing exponentially. However, a significant percentage of these sequences lack functional annotation, which is essential for the understanding of how ... -
Linearized Siderophore Products Secreted via MacAB Efflux Pump Protect Salmonella enterica Serovar Typhimurium from Oxidative Stress
(American Society for Microbiology, 2020-05-05)Nontyphoidal salmonellae (NTS) are exposed to reactive oxygen species (ROS) during their residency in the gut. To survive oxidative stress encountered during infection, salmonellae employ several mechanisms. One of these ... -
Oncogenic Serine 45-Deleted β-Catenin Remains Susceptible to Wnt Stimulation and APC Regulation in Human Colonocytes
(MDPI, 2020-07-30)The Wnt/β-catenin signaling pathway is deregulated in nearly all colorectal cancers (CRCs), predominantly through mutation of the tumor suppressor Adenomatous Polyposis Coli (APC). APC mutation is thought to allow a ... -
APC controls Wnt-induced β-catenin destruction complex recruitment in human colonocytes
(Nature Research, 2020-02-19)Wnt/β-catenin signaling is essential for intestinal homeostasis and is aberrantly activated in most colorectal cancers (CRC) through mutation of the tumor suppressor Adenomatous Polyposis Coli (APC). APC is an essential ... -
Coronavirus infection and PARP expression dysregulate the NAD metabolome: An actionable component of innate immunity
(Elsevier, 2020-12-25)Poly(ADP-ribose) polymerase (PARP) superfamily members covalently link either a single ADP-ribose (ADPR) or a chain of ADPR units to proteins using NAD as the source of ADPR. Although the well-known poly(ADP-ribosylating) ... -
PARP14: A key ADP-ribosylating protein in host–virus interactions?
(Public Library of Science, 2022-06-09)Over 300 posttranslational modifications (PTMs) are known to modify the functions of proteins by affecting processes ranging from activation, degradation, localization, secretion, recognition, and regulation [1]. One such ... -
Efficacy of an HSV-1 Neuro-Attenuated Vaccine in Mice Is Reduced by Preventing Viral DNA Replication
(MDPI, 2022-04-22)We previously isolated an HSV-1 mutant, KOS-NA, that contains two non-synonymous mutations in UL39. One of the mutations, resulting in an R950H amino acid substitution in ICP6, renders KOS-NA severely neuro-attenuated and ... -
Inter-species lateral gene transfer focused on the Chlamydia plasticity zone identifies loci associated with immediate cytotoxicity and inclusion stability
(Wiley, 2021-11-04)Chlamydia muridarum actively grows in murine mucosae and is a representative model of human chlamydial genital tract disease. In contrast, C. trachomatis infections in mice are limited and rarely cause disease. The factors ... -
CRC-derived exosomes containing the RNA binding protein HuR promote lung cell proliferation by stabilizing c-Myc mRNA
(Taylor and Francis, 2022-02-07)HuR overexpression is related to poor survival in patients with colon cancer. HuR overexpression leads to stabilization of tumor-promoting mRNAs by binding to 3′UTR-resident AREs. Exosomes, nanosized lipid bilayer vesicles, ... -
Pseudomonas aeruginosa Bacterioferritin Is Assembled from FtnA and BfrB Subunits with the Relative Proportions Dependent on the Environmental Oxygen Availability
(MDPI, 2022-02-25)Ferritins are iron storage proteins assembled from 24 subunits into a spherical and hollow structure. The genomes of many bacteria harbor genes encoding two types of ferritin-like proteins, the bacterial ferritins (Ftn) ... -
Wild-type Caenorhabditis elegans isolates exhibit distinct gene expression profiles in response to microbial infection
(BMC, 2022-03-23)The soil-dwelling nematode Caenorhabditis elegans serves as a model system to study innate immunity against microbial pathogens. C. elegans have been collected from around the world, where they, presumably, adapted to ... -
Mechanism of Peptide Agonist Binding in CXCR4 Chemokine Receptor
(Frontiers Media, 2022-03-11)Chemokine receptors are key G-protein-coupled receptors (GPCRs) that control cell migration in immune system responses, development of cardiovascular and central nervous systems, and numerous diseases. In particular, the ... -
The 15-aa repeat region of Adenomatous polyposis coli is intrinsically disordered and retains conformational flexibility upon binding β-catenin
(American Chemical Society, 2020-10-20)The tumor suppressor Adenomatous polyposis coli (APC) is a large, multidomain protein with many identified cellular functions. The best characterized role of APC is to scaffold a protein complex that negatively regulates ... -
Caenorhabditis elegans ETR-1/CELF has broad effects on the muscle cell transcriptome, including genes that regulate translation and neuroblast migration
(BMC, 2022-01-06)Migration of neuroblasts and neurons from their birthplace is central to the formation of neural circuits and networks. ETR-1 is the Caenorhabditis elegans homolog of the CELF1 (CUGBP, ELAV-like family 1) RNA-processing ... -
Positive Selection and Horizontal Gene Transfer in the Genome of a Male-Killing Wolbachia
(Oxford University Press, 2021-10-18)Wolbachia are a genus of widespread bacterial endosymbionts in which some strains can hijack or manipulate arthropod host reproduction. Male killing is one such manipulation in which these maternally transmitted bacteria ... -
The Conserved Macrodomain Is a Potential Therapeutic Target for Coronaviruses and Alphaviruses
(MDPI, 2022-01-14)Emerging and re-emerging viral diseases pose continuous public health threats, and effective control requires a combination of non-pharmacologic interventions, treatment with antivirals, and prevention with vaccines. The ... -
The Immunoglobulin Superfamily Members syg-2 and syg-1 Regulate Neurite Development in C. elegans
(MDPI, 2022-01-09)Neurons form elaborate networks by guiding axons and dendrites to appropriate destinations. Neurites require information about the relative body axes during the initial projection from the cell body, and failure to receive ... -
Rapid divergence of the male reproductive proteins in the Drosophila dunni group and implications for postmating incompatibilities between species
(Oxford University Press, 2021-02-18)Proteins involved in post-copulatory interactions between males and females are among the fastest evolving genes in many species, usually attributed to their involvement in reproductive conflict. As a result, these proteins ... -
