These GRB4 ELISA kits are immunodetection tools for measuring the levels of GRB4 in biological samples. GRB4 is an alias of the human NCK2 gene, which encodes the protein, NCK adaptor protein 2. Notably, GRB4 is known to play a role in cell migration and the regulation of cell proliferation, among other functions. The NCK2 protein is described to be 380 amino acid residues in length and 42.9 kilodaltons in mass. It is localized to the ER and cytoplasm of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be phosphorylated. Other names for this target antigen include .
