Abstract As structure prediction methods are generating millions of publicly available protein structures, searching these databases is becoming a bottleneck. Foldseek aligns the query against database by describing tertiary amino acid interactions within proteins as sequences over structural alphabet. decreases computation times four to five orders magnitude with 86%, 88% and 133% sensitivities Dali, TM-align CE, respectively.

Abstract Deep-learning (DL) methods like DeepMind’s AlphaFold2 (AF2) have led to substantial improvements in protein structure prediction. We analyse confident AF2 models from 21 model organisms using a new classification protocol (CATH-Assign) which exploits novel DL for structural comparison and classification. Of ~370,000 models, 92% can be assigned 3253 superfamilies our CATH domain superfamily The remaining cluster into 2367 putative superfamilies. Detailed manual analysis on 618 of...

RNA-guided systems provide remarkable versatility, enabling diverse biological functions. Through iterative structural and sequence homology-based mining starting with a guide RNA-interaction domain of Cas9, we identified family DNA-targeting proteins in phage parasitic bacteria. Each system consists Tandem Interspaced Guide RNA (TIGR) array TIGR-associated (Tas) protein containing Nop domain, sometimes fused to HNH (TasH) or RuvC (TasR) nuclease domains. We show that TIGR arrays are...

Significance Pancreatic cancer is notoriously treatment resistant. These tumors rely on lysosome-dependent recycling pathways to generate substrates for metabolism, which are inhibited by chloroquine (CQ) and its derivatives. However, clinical efficacy of CQ as a monotherapy or combined with standard-of-care regimens has been limited. Using an unbiased kinome screen, we identify replication stress induced vulnerability due impaired de novo nucleotide biosynthesis find that combination...

Existing research has investigated student problem-solving strategies across science, technology, engineering, and mathematics; however, there is limited work in undergraduate biology education on how various aspects that influence learning combine to generate holistic approaches problem solving. Through the lens of situated cognition, we consider solving as a phenomenon involves interactions between internal cognition learner external environment. Using phenomenography methodology, through...

Abstract Background Homologous recombination deficiency (HRD) stands as a clinical indicator for discerning responsive outcomes to platinum-based chemotherapy and poly ADP-ribose polymerase (PARP) inhibitors. One of the conventional approaches HRD prognostication has generally centered on identifying deleterious mutations within BRCA1/2 genes, along with quantifying genomic scars, such Genomic Instability Score (GIS) estimation scarHRD. However, scarHRD method limitations in scenarios...

Although many proteins necessitate well-folded structures to properly instigate their biological functions, a large fraction of functioning contain regions—known as intrinsically disordered protein regions—where stable are not likely form. Notable functional roles in transcriptional regulation, translation, and cellular signal transduction. Moreover, regions highly abundant associated with various human diseases, therefore these segments have become attractive drug targets for potential...
