UBA1/GARS-dependent pathways drive sensory-motor connectivity defects in spinal muscular atrophy [PDF]
Deafferentation of motor neurons as a result of defective sensory-motor connectivity is a critical early event in the pathogenesis of spinal muscular atrophy, but the underlying molecular pathways remain unknown.

Shared and distinct mechanisms of UBA1 inactivation across different diseases
Most cellular ubiquitin signaling is initiated by UBA1, which activates and transfers ubiquitin to tens of E2 enzymes. Clonally acquired UBA1 missense mutations cause an inflammatory-hematologic overlap disease called VEXAS (vacuoles, E1, X-linked ...

UBA1 promotes cardiac hypertrophy by suppressing autophagy via targeting ATG5 for ubiquitination [PDF]
Background Pathological cardiac hypertrophy frequently leads to heart failure (HF). UBA1, the key E1 ubiquitin-activating enzyme, initiates ubiquitin-proteasome signaling and contributes to various diseases, yet its mechanism in cardiac hypertrophy ...

Cryo-EM structures of UBA6 reveal mechanisms of E1–E2 specificity and dual FAT10/ubiquitin thioester transfer [PDF]
UBA1 and UBA6 define parallel ubiquitin (Ub) activation systems that perform non-overlapping roles in Ub and ubiquitin-like protein (Ubl) signaling. Whereas UBA1 supports the canonical Ub pathway, UBA6 also activates the Ubl FAT10, linking Ub signaling ...

Joint involvement in VEXAS and non-VEXAS clonal haematopoiesis: two clusters from a multicentre regional cohort [PDF]
Objective: To describe the joint manifestations associated with clonal haematopoiesis and to compare patients with and without VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome.

Case Report: Early-onset VEXAS syndrome with recurrent pulmonary inflammation and myelodysplasia: a diagnostic and therapeutic challenge [PDF]
BackgroundVEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a newly recognized adult-onset autoinflammatory disorder caused by somatic mutations in the UBA1 gene. It typically presents in older males with systemic inflammation,

Case Report: VEXAS syndrome with extensive pulmonary, cardiac, and skeletal involvement [PDF]
VEXAS syndrome is a rare and severe systemic inflammatory disorder caused by somatic mutations in the X-linked UBA1 gene, primarily affecting men. Since its initial description in 2020, it has been recognized for its complex clinical phenotype and ...
