  • Description

  • Application Data


An antibody raised against Rho GTPase-activating protein 26 (ARHGAP26); a small G protein family protein, GRAF-1 regulates RhoA and CDC42. ARHGAP26 dysregulation is linked to numerous cancers, hematopoietic disorders, and auto-immune cerebellar ataxia.

Material Safety Data Sheet (MSDS)

Rho GTPase-activating protein 26 (ARHGAP26) is a GTPase-activating protein (GAP) for the small GTPases of the Rho family. ARHGAP26 converts RhoA (GTP-RhoA) and CDC42 (GTP-CDC42) to their inactive inactive GDP-bound forms. ARHGAP26 is critical for muscle development also plays important roles in malignant blood tumours and auto-immune cerebellar ataxia. ARHGAP26 expression is downregulated in patent human ductus arteriosus (DA) tissue.

ARHGAP26 is a tumour suppressor gene. ARHGAP26 expression is low in ovarian cancer tissues and is associated with a poor overall survival. ARHGAP26 is also inactivated in acute myeloid leukaemia (AML) and downregulated in glioblastoma. ARHGAP26 upregulation can inhibit lung metastasis. Translocation and point mutations of ARHGAP26 have been linked to the aggressive paediatric disorder juvenile myelomonocytic (JMML).
