ARHGAP28 Proteins and Enzymes

The ARHGAP28 gene encodes for a Rho GTPase-activating protein 28 that converts them to an inactive GDP-bound state. ARHGAP28 exists in four isoforms: isoform 1 is 729 amino acids long, 82 kDA; isoform 2 is 670 amino acids long, 75 kDA; isoform 3 is 545 amino acids long, nearly 62 kDA; isoform 5 is 570 amino acids long, 64 kDA (note, there is no isoform 4). ARHGAP28 functions in signal transduction and Rho GTPase cycle and has been investigated in various diseases such as benign meningioma.
