The following RAS guanyl releasing protein 4 ELISA kits are useful research tools for the measurement of RAS guanyl releasing protein 4 in biological samples. In humans this protein is encoded by the RASGRP4 gene. This protein is known to function as a cation- and diacylglycerol (DAG)-regulated nucleotide exchange factor activating Ras through the exchange of bound GDP for GTP. The canonical protein structure is reported to have an amino acid length of 673 residues, a mass of 74.9 kDa, and is a member of the RASGRP protein family. Its subcellular location is known to be in the cell membrane and cytoplasm. In addition, it is noted to be expressed by mast cells and their progenitors. As many as 8 protein isoforms have been reported. This protein may also be known as guanyl nucleotide releasing protein 4.
