Enables the transfer of a purine nucleotide, any compound consisting of a purine nucleoside esterified with (ortho)phosphate, from one side of a membrane to the other.

A process in which non-proliferating myoblasts, after migrating to the site of injury, fuse into existing damaged fibers or fuse to myotubes to form new fibers, as part of the process of skeletal muscle regeneration. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.

A process in which non-proliferating myoblasts fuse to existing fibers or to myotubes to form new fibers. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.

The chemical reactions and pathways resulting in the breakdown of a fragment of RNA, such as excised introns or sequences removed from ribosomal RNA during processing.

The process aimed at the progression of a myotube cell over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. This occurs as part of the process of skeletal muscle regeneration. Myotubes are multinucleated cells that are formed when proliferating myoblasts exit the cell cycle, differentiate and fuse.

Catalysis of the reaction: 2 Fe3+-siderophore + electron donor -> 2 Fe3+-siderophore + electron acceptor.

Catalysis of an oxidation-reduction in which the oxidation state of metal ion is altered.

Cleavage of the 5'-cap of a nuclear mRNA triggered by shortening of the poly(A) tail to below a minimum functional length.

Cleavage of the 5'-methylguanosine-cap of an mRNA. The methylguanosine-cap is present at the 5'-end of eukaryotic mRNAs. Decapping inactivates translation initiation and promotes 5'-to-3' decay of mRNA.

The process whose specific outcome is the progression of a muscle cell over time, from its formation to the mature structure. Muscle cell development does not include the steps involved in committing an unspecified cell to the muscle cell fate.

The process that initiates skeletal muscle satellite cell division by causing it to move from quiescence to the G1 stage of the cell cycle. The cell swells and there are a number of other small changes. The cells then start to divide. Following cell division the cells will differentiate. In adult muscle, satellite cells become activated to divide and differentiate in response to muscle damage.

The change of a skeletal muscle satellite cell from a mitotically quiescent to a mitotically active state following exposure to some activating factor such as a cellular or soluble ligand. In adult muscle, satellite cells become activated to divide and differentiate in response to muscle damage.

The process in which a relatively unspecialized cell acquires specialized features of a striated muscle cell; striated muscle fibers are divided by transverse bands into striations, and cardiac and voluntary muscle are types of striated muscle.

Any process that modulates the frequency, rate or extent of smooth muscle cell migration.

Any process that activates, maintains or increases the frequency, rate or extent of smooth muscle cell migration.

Shortening of the poly(A) tail of a nuclear-transcribed mRNA from full length to an oligo(A) length.

Binding to a magnesium (Mg) ion.

Binding to a metal ion.

A major pathway of degradation of nuclear-transcribed mRNAs that proceeds through a series of ordered steps that includes poly(A) tail shortening and that can regulate mRNA stability.

Catalysis of the reaction: a 1-phosphatidyl-1D-myo-inositol 3-phosphate + ATP = a 1-phosphatidyl-1D-myo-inositol 3,5-bisphosphate + ADP + 2 H(+).
