Compensatory Interplay Between Clarin‐1 and Clarin‐2 Deafness‐Associated Proteins Governs Phenotypic Variability in Hearing

Advanced Science, EarlyView.
Functional compensation between clarin‐1 and clarin‐2 in cochlear hair cells. Hearing loss associated with CLRN1 mutations shows striking phenotypic variability; however, the underlying mechanisms remain poorly understood. This study reveals that clarin‐1 and clarin‐2 function cooperatively in cochlear hair cells to sustain mechanoelectrical ...

RGS10 shapes the hemostatic response to injury through its differential effects on intracellular signaling by platelet agonists. [PDF]

, 2018
Platelets express ≥2 members of the regulators of G protein signaling (RGS) family. Here, we have focused on the most abundant, RGS10, examining its impact on the hemostatic response in vivo and the mechanisms involved.

Automatically Defining Protein Words for Diverse Functional Predictions Based on Attention Analysis of a Protein Language Model

Advanced Science, EarlyView.
Understanding protein sequence–function relationships remains challenging due to poorly defined motifs and limited residue‐level annotations. An annotation‐agnostic framework is introduced that segments protein sequences into “protein words” using attention patterns from protein language models.

ARHGAP11A, a member of Rho GTPase activating protein family, as a prognostic biomarker linked to DNA damage response across pan-cancer

BMC Cancer
Background The Rho GTPase-activating protein (RhoGAP) family represents a large and diverse group of proteins that act as key regulators of Rho GTPases, small GTP-binding proteins involved in cellular signaling. Tight regulation of Rho GTPase activity is

Deciphering the Impact of RAC1‐SPTAN1 in ARPKD Cystogenesis Using Multifaceted Models

Advanced Science, EarlyView.
Distal/connecting tubules expressing SLC8A1 have been suggested as a potential origin of ARPKD cysts. SPTAN1 has been identified as a key molecule in ARPKD cyst formation. Restoring SPTAN1 in PKHD1−/− organoids reduced cyst formation, normalized calcium levels, and decreased RAC1/c‐FOS expression, highlighting SPTAN1's role in ARPKD and the potential ...

Ferroptosis: The Demise of Cells Through Phospholipid Peroxidation

Advanced Science, EarlyView.
The relative abundance of peroxidation‐resistant monounsaturated fatty acids (MUFAs) vs. peroxidation‐sensitive polyunsaturated fatty acids (PUFAs) incorporated into phospholipid (PL) is a key determinant of ferroptosis sensitivity, as the peroxidation of PL PUFA acyl chains (PUFA‐PL) disrupts membrane integrity, causing ferroptotic cell death ...

The GAPs, GEFs, and GDIs of heterotrimeric G-protein alpha subunits

International Journal of Biological Sciences, 2005
The heterotrimeric G-protein alpha subunit has long been considered a bimodal, GTP-hydrolyzing switch controlling the duration of signal transduction by seven-transmembrane domain (7TM) cell-surface receptors.

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

Advanced Science, EarlyView.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...

Dynamic cofilin phosphorylation in the control of lamellipodial actin homeostasis [PDF]

, 2007
During animal cell chemotaxis, signalling at the plasma membrane induces actin polymerisation to drive forward cell movement. Since the cellular pool of actin is limited, efficient protrusion formation also requires the coordinated disassembly of pre ...

Co-expression of Gbeta 5 Enhances the Function of Two Ggamma Subunit-like Domain-containing Regulators of G Protein Signaling Proteins [PDF]

, 2000
Regulators of G protein signaling (RGS) stimulate the GTPase activity of G protein Galpha subunits and probably play additional roles. Some RGS proteins contain a Ggamma subunit-like (GGL) domain, which mediates a specific interaction with Gbeta 5. The
