RHOH (Ras Homolog Family Member H) is a small GTPase belonging to the Rho family, which plays critical roles in regulating cytoskeletal dynamics, cell signaling, and immune cell functions. Unlike typical Rho GTPases, RHOH lacks intrinsic GTPase activity due to amino acid substitutions in its catalytic domain, rendering it constitutively active or locked in a GTP-bound state. It is predominantly expressed in hematopoietic cells, particularly T and B lymphocytes, where it influences cell development, activation, and migration. RHOH integrates signals from antigen receptors, chemokine receptors, and cytokine pathways, modulating immune responses through interactions with downstream effectors like Wiskott-Aldrich syndrome protein (WASP) and PAK kinases.
Research highlights RHOH's dual roles in oncogenesis and immune regulation. It acts as a tumor suppressor in certain contexts by inhibiting T-cell receptor (TCR)-mediated signaling, yet it can also promote lymphoma progression when dysregulated. Mutations or aberrant expression of RHOH are linked to hematologic malignancies, autoimmune disorders, and immunodeficiency syndromes. Recombinant RHOH protein, produced via engineered expression systems (e.g., E. coli or mammalian cells), serves as a tool to study its biochemical properties, structure-function relationships, and signaling mechanisms. Its applications span drug discovery, molecular interaction studies, and elucidating mechanisms underlying immune dysregulation and cancer, offering potential therapeutic targets for related diseases.
