Anti-RASGRP4 antibodies are used in the immunodetection of the protein RAS guanyl releasing protein 4. In humans, the canonical protein has a reported length of 673 amino acid residues and a mass of 74.9 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 8 different isoforms have been reported for this protein. It is noted to be expressed by mast cells and their progenitors. A member of the RASGRP protein family, RasGRP4 is known to function as a cation- and diacylglycerol (DAG)-regulated nucleotide exchange factor activating Ras through the exchange of bound GDP for GTP. Synonyms for this target antigen include guanyl nucleotide releasing protein 4. RASGRP4 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Western Blot is the most common application for the RasGRP4 antibodies listed below. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
