UniProt annotation for DYSF_HUMAN » Dysferlin
FUNCTION: Key calcium ion sensor involved in the Ca(2+)-triggered synaptic vesicle-plasma membrane fusion. Plays a role in the sarcolemma repair mechanism of both skeletal muscle and cardiomyocytes that permits rapid resealing of membranes disrupted by mechanical stress (By similarity).

SUBUNIT: Interacts with CACNA1S. Interacts with ANXA1; the interaction is Ca(2+)- and injury state-dependent. Interacts with ANXA2; the interaction is Ca(2+)- and injury state-dependent. Interacts with CACNA1S and PARVB. Interacts with TRIM72/MG53; interaction is required for transport to sites of cell injury during repair patch formation (By similarity). Interacts with CAV3 and PARVB. Interacts with AHNAK; the interaction is direct and Ca(2+)-independent. Interacts with AHNAK2; the interaction is direct and Ca(2+)-independent.

TISSUE SPECIFICITY: Expressed in skeletal muscle, myoblast, myotube and in the syncytiotrophoblast (STB) of the placenta (at protein level). Ubiquitous. Highly expressed in skeletal muscle. Also found in heart, brain, spleen, intestine, placenta and at lower levels in liver, lung, kidney and pancreas.

DEVELOPMENTAL STAGE: Expression in limb tissue from 5-6 weeks embryos; persists throughout development.

DOMAIN: All seven C2 domains associate with lipid membranes in a calcium-dependent manner. Domains C2 1 and 3 have the highest affinity for calcium, the C2 domain 1 seems to be largely unstructured in the absence of bound ligands. The C2 domain 1 from isoform 14 does not bind calcium in the absence of bound phospholipid (PubMed, PubMed).

DISEASE: Limb-girdle muscular dystrophy 2B (LGMD2B) OMIM: An autosomal recessive degenerative myopathy characterized by weakness and atrophy starting in the proximal pelvifemoral muscles, with onset in the late teens or later, massive elevation of serum creatine kinase levels and slow progression. Scapular muscle involvement is minor and not present at onset. Upper limb girdle involvement follows some years after the onset in lower limbs. disease is caused by mutations affecting the gene represented in this entry.

DISEASE: Miyoshi muscular dystrophy 1 (MMD1) OMIM: A late- onset muscular dystrophy involving the distal lower limb musculature. It is characterized by weakness that initially affects the gastrocnemius muscle during early adulthood. affecting the gene represented in this entry.

DISEASE: Distal myopathy with anterior tibial onset (DMAT) OMIM: Onset of the disorder is between 14 and 28 years of age and the anterior tibial muscles are the first muscle group to be involved. Inheritance is autosomal recessive. Note=The disease is caused by mutations affecting the gene represented in this entry.
