UNLABELLED Anecdotal evidence suggests that chronic bladder pain improves while breastfeeding. The present study sought to identify potential mechanisms for such a phenomenon by investigating the effects of the lactogenic hormones prolactin (PL) and oxytocin (OXY) in a rat model of bladder nociception. Lactating rats were less sensitive to urinary bladder distension (UBD) than controls. In inve...

Cockayne syndrome B (CSB), best known for its role in transcription-coupled nucleotide excision repair (TC-NER), contains a ubiquitin-binding domain (UBD), but the functional connection between protein ubiquitylation and this UBD remains unclear. Here, we show that CSB is regulated via site-specific ubiquitylation. Mass spectrometry analysis of CSB identified lysine (K) 991 as a ubiquitylation ...

Post-translational modification by ubiquitin (ubiquitination, ubiquitylation, ubiquitinylation) is used as a robust signaling mechanism in a variety of processes that are essential for cell homeostasis. Its signaling specificity is conferred by the inherent dynamics of ubiquitin, the multivalency of ubiquitin chains, and its subcellular context, often defined by ubiquitin receptors and the subs...

Abstract Overbalanced drilling is the most common technique; nevertheless, it has several disadvantages such as formation damage, mud losses, and stuck pipes; challenges that are in high permeability zones highly fractured formations. To overcome those issues, underbalanced method could be implemented. The (UBD) technique widely utilized hard, under pressure, depleted, fractured/vuggy Low-densi...

In the cytoplasm, the correct delivery of membrane proteins is an essential and highly regulated process. The posttranslational targeting of the important tail-anchor membrane (TA) proteins has recently been under intense investigation. A specialized pathway, called the guided entry of TA proteins (GET) pathway in yeast and the transmembrane domain recognition complex (TRC) pathway in vertebrat...

Ubiquitylation provides a rapid alternative to control the activity of crucial cellular factors through the remodelling of a target protein. Diverse ubiquitin chains are recognized by domains with affinity for UBDs (ubiquitin-binding domains) present in receptor/effector proteins. Interestingly, some proteins contain more than one UBD and the preservation of this structure in many species sugge...
