Phosphorylation of distal C-terminal residues promotes TRPV4 channel activation in response to arachidonic acid.

Transient receptor potential vanilloid 4 (TRPV4) is a Ca-permeable channel activated by diverse physical and chemical stimuli, including mechanical stress and endogenous lipid arachidonic acid (AA) and its metabolites. Phosphorylation of TRPV4 by protein kinase A (PKA) and protein kinase C (PKC) is a predominant mechanism for channel regulation, especially in the cytoplasmic domains due to their importance in protein assembly, and channelopathies. However, studies corresponding to phosphorylation sites for these kinases remain incomplete.

Decoding the mA epitranscriptomic landscape for biotechnological applications using a direct RNA sequencing approach.

Epitranscriptomic modifications, particularly N6-methyladenosine (mA), are crucial regulators of gene expression, influencing processes such as RNA stability, splicing, and translation. Traditional computational methods for detecting mA from Nanopore direct RNA sequencing (DRS) data are constrained by their reliance on experimentally validated labels, often resulting in the underestimation of modification sites. Here, we introduce pum6a, an innovative attention-based framework that integrates positive and unlabeled multi-instance learning (MIL) to address the challenges of incomplete labeling and missing read-level annotations.
