No, cells are composed of all macromolecules: proteins, lipids, carbohydrates, and nucleic acids. Cells definitely contain protein in the membranes and organelles, but they're not wholly made up of protein or are a type of protein.

the both cells have ribosomes for protein sysnthesis.. but the type of ribosome differs...
Proteins are a type of molecule synthesized from amino acids in cells.

An antibody is a highly specific protein that attaches itself to a foreign substance.
The type of membrane protein that anchors cells to neighboring cells and to protein filaments both outside and inside the cell is known as an integrin. Integrins are transmembrane proteins that facilitate cell adhesion to the extracellular matrix and other cells by binding to specific ligands. They play a crucial role in cellular signaling and maintaining tissue structure by connecting the cytoskeleton to the extracellular environment.
