The directed movement of the nucleus to a specific location within a cell.

Any process that activates or increases the frequency, rate or extent of cell migration.

The directed movement of the nucleus along microfilaments within the cell, mediated by motor proteins.

Any process in which a centrosome is transported to, and/or maintained in, a specific location within the cell.

The process in which cytoskeletal filaments are directly or indirectly linked to the nuclear membrane.

An inclusion body formed by dynein-dependent retrograde transport of an aggregated protein on microtubules.

Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space.

Cytoskeletal structure made from intermediate filaments, typically organized in the cytosol as an extended system that stretches from the nuclear envelope to the plasma membrane. Some intermediate filaments run parallel to the cell surface, while others traverse the cytosol; together they form an internal framework that helps support the shape and resilience of the cell.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

The double lipid bilayer enclosing the nucleus and separating its contents from the rest of the cytoplasm; includes the intermembrane space, a gap of width 20-40 nm (also called the perinuclear space).

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

A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

A fine reticular network of membrane-limited elements that pervades the sarcoplasm of a muscle cell; continuous over large portions of the cell and with the nuclear envelope; that part of the endoplasmic reticulum specialized for calcium release, uptake and storage.

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

The portion of the plasma membrane surrounding a lamellipodium.

The portion of the plasma membrane surrounding a filopodium.

The volume enclosed by the nuclear inner membrane.

A nuclear membrane protein complex which connects the nuclear outer and inner membranes together, and links links the nuclear lumen to cytoplasmic microtubules during meiosis.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
