The structure and regulation of human muscle α-actinin.

abstract：:The intermediate filament proteins, desmin and vimentin, are phosphorylated in skeletal muscle cells in vivo. Desmin kinase activities have been purified from mature chicken skeletal muscle and identified as the cAMP-dependent kinases. Chicken skeletal muscle contains two cAMP-dependent protein kinases which are simil...

When cells have sufficient amino acids, TORC1 is active due to its lysosomal localization mediated via the Rag GTPases. Upon amino acid removal, the Rag GTPases release TORC1, causing it to become cytoplasmic and inactive. We show ...
