SRP-35, a newly identified protein of the skeletal muscle sarcoplasmic reticulum, is a retinol dehydrogenase.
In the present study we provide evidence that SRP-35, a protein we identified in rabbit skeletal muscle sarcoplasmic reticulum, is an all-trans-retinol dehydrogenase. Analysis of the primary structure and tryptic digestion revealed that its N-terminus encompasses a short hydrophobic sequence bound to the sarcoplasmic reticulum membrane, whereas its C-terminal catalytic domain faces the myoplasm...
متن کاملCalcium binding protein changes of sarcoplasmic reticulum from rat denervated skeletal muscle.
Two Ca2+ sequestering proteins were studied in fast-twitch (EDL) and slow-twitch (soleus) muscle sarcoplasmic reticulum (SR) as a function of denervation time. Ca2+-ATPase activity measured in SR fractions of normal soleus represented 5% of that measure in SR fractions of normal EDL. Denervation caused a severe decrease in activity only in fast-twitch muscle. Ca2+-ATPase and calsequestrin conte...
متن کاملIsolation and Characterization of the Sarcoplasmic Reticulum of Skeletal Muscle
The sarcoplasmic reticulum (SR) of rabbit skeletal muscle was studied after isolation of a vesicle fraction and of vesicular subfractions by means of differential and density gradient centrifugations. The different fractions were examined electron microscopically by negative and positive staining; their content in protein and phospholipid and their ability to bind Ca(++) were determined. After ...
متن کاملPolymorphism of sarcoplasmic-reticulum adenosine triphosphatase of rabbit skeletal muscle.
Antibody was raised in chickens against purified sarcoplasmic-reticulum Ca2+-activated ATPase (Ca2+-ATPase). The immunological relationship between the Ca2+-ATPase of fast-muscle and slow-muscle sarcoplasmic reticulum was investigated by a one-step and a two-step competitive enzyme-linked immunosorbent assay (ELISA). The results show marked antigenic differences between the membrane-bound Ca2+-...
متن کاملRole of sarcoplasmic reticulum junctional proteins in skeletal muscle strength
Background Skeletal muscle constitutes approximately 40% of body mass, and age-induced decrease of muscle strength impinge on daily activities and on normal social life in the elderly. Loss of muscle strength has been recognised as a debilitating and life threatening condition also in cachexia in cancer patients and in clinical conditions associated with prolonged bed rest. Skeletal muscle dihy...
