The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.

The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.

The resolution of the male germline syncytium or cyst into individual gametes by packaging each spermatid into its own plasma membrane.

The specification of the anterior/posterior axis of the embryo by the products of genes expressed maternally and genes expressed in the zygote.

Movement of organelles or other particles along actin filaments, or sliding of actin filaments past each other, mediated by motor proteins.

The assembly and arrangement of a rhabdomere within a cell. The rhabdomere is the organelle on the apical surface of a photoreceptor cell that contains the visual pigments.

Any process that activates or increases the frequency, rate or extent of the process in which oskar mRNA is transported to, or maintained in, the oocyte pole plasm.

The directed movement of a mitochondrion along a microtubule, mediated by motor proteins.

The specialized microvilli-containing organelle on the apical surfaces of a photoreceptor cell containing the visual pigment rhodopsin and most of the proteins involved in phototransduction.

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 myosin complex containing a dimer of class V myosin heavy chains and associated light chains; involved in intracellular transport. Myosin V is a dimeric molecule consisting of conserved motor domains followed by 6 IQ motifs which bind specific light chains and calmodulin. The tail domain is important for cellular localization and cargo binding and can be divided into an alpha-helical coiled coil region and a C-terminal globular region.

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.
