A membrane-bounded compartment that is found at the base of the rhabdomere and contains stored calcium, InsP3 receptors and smooth endoplasmic reticulum Ca2+-ATPase. The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth. Any constituent part of a flagellum, a long whiplike or feathery structure borne either singly or in groups by the motile cells of many bacteria and unicellular eukaryotes and by the motile male gametes of many eukaryotic organisms, which propel the cell through a liquid medium. A prolongation or process extending from a cell, e.g. a flagellum or axon. Any constituent part of a cell projection, a prolongation or process extending from a cell, e.g. a flagellum or axon. All of the contents of a cell projection, excluding the plasma membrane surrounding the projection. Inward projections of the cytoskeletal structures of the oral apparatus, which form a fiber that extends past the cytostome into the cytoplasm. The end of a filopodium distal to the body of the cell. Any constituent part of a cilium, a specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole. Protrusion from a dendrite. Spines are specialised subcellular compartments involved in the synaptic transmission. They are linked to the dendritic shaft by a restriction. Because of their bulb shape, they function as a biochemical and an electrical compartment. Spine remodeling is though to be involved in synaptic plasticity. Cylindric portion of the dendrite, directly stemming from the perikaryon, and carrying the dendritic spines. A short cylindrical array of microtubules and associated proteins found at the base of a eukaryotic cilium or flagellum that is similar in structure to a centriole. The basal body serves as a nucleation site for axoneme growth. The portion of the plasma membrane surrounding a cell surface projection. The specialized, terminal region of a neuron projection such as an axon or a dendrite. The bundle of microtubules and associated proteins that forms the core of cilia and flagella in eukaryotic cells and is responsible for their movements. Protein complex that has a role in determining cell polarity, found at the tip of the mating projection in unicellular fungi exposed to mating pheromone. The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope. A structure at the distal end of a dendrite adapted to carry out a specific function, e.g. dendriole. The part of a cell or its extracellular environment in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. A dendrite arising from another dendrite. A part of an axon, a cell projection of a neuron. Any constituent part of a pilus, a proteinaceous hair-like appendage on the surface of bacteria ranging from 2-8 nm in diameter. The part of the cortical actin cytoskeleton that forms part of a macropinocytic cup. The region where the mating projection meets the bulk of the cell, in unicellular fungi exposed to mating pheromone. Any constituent part of an axoneme, the bundle of microtubules and associated proteins that forms the core of cilia and flagella in eukaryotic cells and is responsible for their movements. Any constituent part of a cell, the basic structural and functional unit of all organisms. A complex of proteins that are involved in phototransduction and attached to the transient receptor potential (TRP) channel. The protein connections are mediated through inaD.
