The p21 Ras ELISA kits listed below are analytical tools for measuring concentrations of p21 Ras in various samples. p21 Ras is an alternative name for the human HRAS gene, which encodes the protein, HRas proto-oncogene, GTPase. It has been mentioned that p21 Ras plays a role in adipose tissue development and organ morphogenesis, among other functions. Structurally, the HRAS protein is 189 amino acid residues in length and 21.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane, golgi, and cytoplasm of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. This protein is known to be ubiquitinated, palmitoylated, acetylated and glycosylated. Other names for this target antigen include C-BAS/HAS, C-H-RAS, and C-HA-RAS1.
