The maintenance of established anisotropic intracellular organization or cell growth patterns.

The directed movement of tetracycline into, out of, within or between cells. Tetracycline is a broad spectrum antibiotic that blocks binding of aminoacyl tRNA to the ribosomes of both Gram-positive and Gram-negative organisms (and those of organelles).

A large multimeric transcription factor complex that can regulate transcription positively or negatively; consists of a core complex plus additional proteins; may interact with other proteins to control initiation of transcription. In Saccharomyces the core complex comprises Ccr4p, Caf1p, Not1p, Not2p, Not3p, Not4p, and Not5p; Caf4p, Caf16p, and several less well characterized 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.

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.

The directed movement of fatty acids into, out of, within or between cells. Fatty acids are aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis.

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

The directed movement of long-chain fatty acids into, out of, within or between cells. A long-chain fatty acid is an aliphatic compound with a terminal carboxyl group and with a chain length greater than C12.

Catalysis of the preferential cleavage of Arg-Xaa, Lys-Xaa, but with more restricted specificity than trypsin.

A type of chromosome in a polyploid cell, formed when multiple copies of homologous chromosomes are aligned side by side to give a giant chromosome in which distinct chromosome bands are readily visible.

A region at which the centric regions of polytene chromosomes are joined together.

Assembly of actin filaments by the addition of actin monomers to a filament.
