Binding to a flavonol, a flavonoid that contains a 3-hydroxy-2-phenylchromen-4-one backbone.

Binding to a flavanol.

Binding to a catechin, a polyphenolic antioxidant plant metabolite with a flavonoid or flavan-3-ol structure.

Binding to epigallocatechin 3-gallate, a compound that is a gallic acid ester of a catechin.

A process in which a protein or protein complex is maintained in a specific location in the cell cortex of a cell tip, and is prevented from moving elsewhere. The cell cortex of a cell tip is the region directly beneath the plasma membrane at either end of the longest axis of a cylindrical or elongated cell.

A process in which a protein or protein complex is maintained in a specific location in the cell cortex.

A muscle system process that results in an increase in cell number by cell division, often leading to an increase in the size of an organ.

A process in which muscle adapts, with consequent modifications to structural and/or functional phenotypes, in response to a stimulus. Stimuli include contractile activity, loading conditions, substrate supply, and environmental factors. These adaptive events occur in both muscle fibers and associated structures (motoneurons and capillaries), and they involve alterations in regulatory mechanisms, contractile properties and metabolic capacities.

Catalysis of the reaction: polyphosphate + n H2O = (n+1) oligophosphate. The product contains 4 or 5 phosphate residues.

OBSOLETE. Integral to that fraction of cells, prepared by disruptive biochemical methods, that includes the plasma and other membranes; require detergents, such as Triton X-100, to be released from membranes.

The orderly movement of a smooth muscle cell from one site to another, often during the development of a multicellular organism.

The orderly movement of a muscle cell from one site to another, often during the development of a multicellular organism.

The directed movement of spermine, N,N-bis(3-aminopropyl)-1,4-diaminobutane, a polyamine formed by the transfer of a propylamine group from decarboxylated S-adenosylmethionine to spermidine, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Enables the transfer of spermine from one side of a membrane to the other. Spermine is a polybasic amine found in human sperm, in ribosomes and in some viruses, which is involved in nucleic acid packaging. Synthesis is regulated by ornithine decarboxylase which plays a key role in control of DNA replication.

Enables the transfer of polyamines, organic compounds containing two or more amino groups, from one side of a membrane to the other.

A minor degradation pathway nuclear-transcribed mRNAs that begins with an endonucleolytic cleavage to generate unprotected ends.

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

Enables the transfer of adenine nucleotides (AMP, ADP, and ATP) from one side of a membrane to the other.
