A Novel Dysferlin-Binding Kinase CK2α Promotes Plasma Membrane Repair in Dysferlinopathy. [PDF]
When the cell membrane is injured, extracellular calcium enters the cell, triggering the accumulation of dysferlin at the lesion site. In the presence of dysferlin, CK2 is efficiently recruited to the damaged membrane and maintains its kinase activity through interaction with dysferlin.

Enhancing the Performance of a Blood-Based Diagnostic Screening Tool for Dysferlinopathy: Optimising an Immunoassay Across Continents. [PDF]
We validated an immunohistochemical method for detecting dysferlin in neutrophils from peripheral blood films (PBFs), offering a minimally invasive alternative to muscle biopsy. In an Indian cohort, the assay showed 100% sensitivity. Specificity depended on sample quality and storage conditions.

Comprehensive Profiling of Annexins in Neuromuscular Disorders Reveals a Unique Signature in Dysferlinopathy. [PDF]
Muscle biopsies from patients across eight neuromuscular disorders and healthy controls were analyzed using immunofluorescence (IF) and immunoblot (WB) to evaluate the expression and localization of seven annexin proteins (A1, A2, A4, A5, A6, A7, A11).

Contribution of dysferlin deficiency to skeletal muscle pathology in asymptomatic and severe dystroglycanopathy models: generation of a new model for Fukuyama congenital muscular dystrophy. [PDF]
Defects in dystroglycan glycosylation are associated with a group of muscular dystrophies, termed dystroglycanopathies, that include Fukuyama congenital muscular dystrophy (FCMD). It is widely believed that abnormal glycosylation of dystroglycan leads to

Myopathy With Exercise-Induced Intolerance due to Novel Biallelic Variants in OBSCN-A Clinical, Morphological and Molecular Analysis. [PDF]
The phenotype of OBSCN variants consists of exercise intolerance ranging from myalgia and cramps to rhabdomyolysis. Symptoms are mainly induced by high‐intensity sports. Molecular analysis showing a deregulation of muscle processes associated with Ca2+ regulation, extrasarcolemmal integrity and autophagy emphasised the critical role of obscurin in ...

High-Density Lipoprotein-Associated Cholesterol Abnormalities in a Clinical Outcomes Study of Dysferlin-Deficient Limb-Girdle Muscular Dystrophy Type R2. [PDF]
ABSTRACT Background Limb–girdle muscular dystrophy (MD) type R2 (LGMDR2, formerly LGMD2B) is an autosomal recessive form of MD caused by variants in the dysferlin gene, DYSF. It leads to slow proximal and distal muscle weakening that generally results in loss of ambulation around early adulthood but without the lethal cardiorespiratory dysfunction ...

Proteomic analysis of the dysferlin protein complex unveils its importance for sarcolemmal maintenance and integrity. [PDF]
Dysferlin is critical for repair of muscle membranes after damage. Mutations in dysferlin lead to a progressive muscular dystrophy. Recent studies suggest additional roles for dysferlin.

Dysferlin forms a dimer mediated by the C2 domains and the transmembrane domain in vitro and in living cells. [PDF]
Dysferlin was previously identified as a key player in muscle membrane repair and its deficiency leads to the development of muscular dystrophy and cardiomyopathy. However, little is known about the oligomerization of this protein in the plasma membrane.

Modular Dispensability of Dysferlin C2 Domains Reveals Rational Design for Mini-dysferlin Molecules [PDF]
Dysferlin is a large transmembrane protein composed of a C-terminal transmembrane domain, two DysF domains, and seven C2 domains that mediate lipid- and protein-binding interactions. Recessive loss-of-function mutations in dysferlin lead to muscular dystrophies, for which no treatment is currently available.
