Proteins have a wide variety of jobs. Some proteins are used in the maintenance of the cells structure. Proteins can be used to move various portions of the cell do different locations within the cell (eg chromosome movement during mitosis). Other proteins, found in cell membranes are used in the active and passive transport of molecules (eg. aquaporins, sodium channels). Many proteins are enzyme which catalyze reactions within the cell (eg. Hexokinase).

In short proteins (in general) do not have one specific job but different proteins have different functions.
