Any process that activates or increases the frequency, rate or extent of the addition of ubiquitin groups to a protein.

Any process that activates or increases the frequency, rate or extent of the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.

The process whose specific outcome is the progression of the skeletal muscle fiber over time, from its formation to the mature structure. Muscle fibers are formed by the maturation of myotubes. They can be classed as slow, intermediate/fast or fast.

The process in which a relatively unspecialized cell acquires specialized features of a skeletal muscle fiber cell. Skeletal muscle fiber differentiation starts with myoblast fusion and the appearance of specific cell markers (this is the cell development step). Then individual skeletal muscle fibers fuse to form bigger myotubes and start to contract.

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

Self-propelled movement of an organism from one location to another through water, often by means of active fin movement.

The progression of a muscle structure over time, from its formation to its mature state. Muscle structures are contractile cells, tissues or organs that are found in multicellular organisms.

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

A ubiquitin ligase complex in which a cullin from the Cul3 subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by a BTB-domain-containing protein.

The dark-staining region of a sarcomere, in which myosin thick filaments are present; the center is traversed by the paler H zone, which in turn contains the M line.

A region of a sarcomere that appears as a light band on each side of the Z disc, comprising a region of the sarcomere where thin (actin) filaments are not overlapped by thick (myosin) filaments; contains actin, troponin, and tropomyosin; each sarcomere includes half of an I band at each end.
