Disease

[CO6A3_HUMAN] Defects in COL6A3 are a cause of Bethlem myopathy (BM) [MIM:158810]. BM is a rare autosomal dominant proximal myopathy characterized by early childhood onset (complete penetrance by the age of 5) and joint contractures most frequently affecting the elbows and ankles.[1] [2] [3] [4] [5] Defects in COL6A3 are a cause of Ullrich congenital muscular dystrophy (UCMD) [MIM:254090]; also known as Ullrich scleroatonic muscular dystrophy. UCMD is an autosomal recessive congenital myopathy characterized by muscle weakness and multiple joint contractures, generally noted at birth or early infancy. The clinical course is more severe than in Bethlem myopathy.[6] [7]

Function

[CO6A3_HUMAN] Collagen VI acts as a cell-binding protein.

Publication Abstract from PubMed

The C-terminal Kunitz-type domain from the alpha3 chain of human type VI collagen (C5), a single amino-acid residue chain with three disulfide bridges, was refined at 0.9 A resolution in a monoclinic form, space group P2(1) with one molecule per asymmetric unit, using data collected at cryogenic temperature (110 K). The average protein factor decreases from 21 A(2) at room temperature (RT) to 12 A(2) at cryotemperature (100 K, CT). The spatially close N- and C-termini remain highly disordered. The different structural motifs of C5 were analyzed in terms of rigid-body displacement (TLS analyses) and show dominant libration motion for the secondary structure.
