The total complement of proteins present at a time in a cell or cell type is known as its proteome, and the study of such large-scale data sets defines the field of proteomics, named by analogy to the related field of genomics.
O complemento proteico completo presente nun determinado momento nunha célula ou tipo celular denomínase proteoma, e o estudo de conxuntos de datos a grande escala define o campo da proteómica, denominado así por analoxía co campo relacionado da xenómica.
