The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

Any process that activates, maintains or increases the frequency, rate or extent of activation of satellite cell involved in skeletal muscle regeneration. The activation of satellite cell is the process that initiates 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.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a muscle activity stimulus.

Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of SUMO groups to a protein.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that modulates I-kappaB kinase/NF-kappaB signaling.

The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

Any process that activates or increases the frequency, rate or extent of the hydrolysis of a peptide bond or bonds within a protein.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

Any process that modulates the activity of an enzyme.

Any process that activates or increases the frequency, rate or extent of activity of the transcription factor NF-kappaB.

The aggregation, arrangement and bonding together of a set of macromolecules to form a protein-containing complex.

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their own peptide bonds.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The contractile element of skeletal and cardiac muscle; a long, highly organized bundle of actin, myosin, and other proteins that contracts by a sliding filament mechanism.

Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

Invagination of the plasma membrane of a muscle cell that extends inward from the cell surface around each myofibril. The ends of T-tubules make contact with the sarcoplasmic reticulum membrane.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
