Keyword - Cytoplasm (KW-0963)
Protein found in the cytoplasm, the content of a cell within the plasma membrane and, in eukaryotics cells, surrounding the nucleus. This three-dimensional, jelly-like lattice interconnects and supports the other solid structures. The cytosol (the soluble portion of the cytoplasm outside the organelles) is mostly composed of water and many low molecular weight compounds. In eukaryotes, the cytoplasm also contains a network of cytoplasmic filaments (cytoskeleton).
