A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments. Includes processes that control the spatial distribution of actin filaments, such as organizing filaments into meshworks, bundles, or other structures, as by cross-linking.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a lysosome. A lysosome is a cytoplasmic, membrane-bounded organelle that is found in most animal cells and that contains a variety of hydrolases.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

The process whose specific outcome is the progression of the antenna over time, from its formation to the mature structure. The antenna are the sensory structures on the head that are capable of detecting various environmental stimuli.

The series of events required for an organism to receive a visual stimulus, convert it to a molecular signal, and recognize and characterize the signal. Visual stimuli are detected in the form of photons and are processed to form an image.

The process in which anatomical structures of the veins on an imaginal disc-derived wing are generated and organized.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a microvillus on a follicle cell. A microvillus is a thin cylindrical membrane-covered projection on the surface of an animal cell containing a core bundle of actin filaments.

The process that gives rise to the patterns of cell differentiation in the chitin-based larval cuticle. An example of this is found in Drosophila melanogaster.

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

Thin cylindrical membrane-covered projections on the surface of an animal cell containing a core bundle of actin filaments. Present in especially large numbers on the absorptive surface of intestinal cells.

The outer segment of a vertebrate photoreceptor that contains discs of photoreceptive membranes.

The inner segment of a vertebrate photoreceptor containing mitochondria, ribosomes and membranes where opsin molecules are assembled and passed to be part of the outer segment discs.

The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm.

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

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

The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.

A protein complex, formed of one or more myosin heavy chains plus associated light chains and other proteins, that functions as a molecular motor; uses the energy of ATP hydrolysis to move actin filaments or to move vesicles or other cargo on fixed actin filaments; has magnesium-ATPase activity and binds actin. Myosin classes are distinguished based on sequence features of the motor, or head, domain, but also have distinct tail regions that are believed to bind specific cargoes.

A portmanteau term for myosins other than myosin II.

A myosin complex containing one or more class VI myosin heavy chains and associated light chains. Myosin VI has a single IQ motif in the neck and a tail region with a coiled coil domain followed by a unique globular domain; a unique insertion that enables myosin VI to move towards the pointed or minus end of actin filaments.

A myosin complex containing a dimer of class VII myosin heavy chains and associated light chains. Myosin VII (240 kDa) is predicted to be a dimeric molecule with 5 IQ motifs and a tail region with a short stretch of coiled coil followed by two myosin-tail homology (MyTH4) domains, two talin-binding (FERM) domains and an SH3-domain.

The region that lies just beneath the plasma membrane on the apical edge of a cell.

The region that lies just beneath the plasma membrane on the basal edge of a cell.

The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.

An external encapsulating structure part of the chorion. A single cone-shaped specialization that forms an opening in the chorion that allows sperm entry into the egg prior to fertilization.
