ARHGAP17. also known as RICH1 or Nadrin, is a member of the Rho GTPase-activating protein (RhoGAP) family that regulates Rho GTPases, key molecular switches controlling cytoskeletal dynamics and cell signaling. It specifically targets Cdc42. a critical regulator of cell polarity, membrane trafficking, and actin reorganization. By enhancing the intrinsic GTP-hydrolysis activity of Cdc42. ARHGAP17 converts it from an active GTP-bound state to an inactive GDP-bound state, thereby modulating downstream cellular processes.
Structurally, ARHGAP17 contains an N-terminal BAR (Bin/Amphiphysin/Rvs) domain, which facilitates membrane curvature sensing and protein-protein interactions, and a C-terminal RhoGAP domain responsible for its catalytic activity. Additionally, it possesses proline-rich regions that mediate interactions with SH3 domain-containing proteins, linking it to diverse signaling pathways.
Recombinant ARHGAP17 protein is typically produced using bacterial or mammalian expression systems, followed by purification via affinity chromatography. Its recombinant form enables functional studies, including in vitro GTPase activity assays, structural analysis, and exploration of binding partners. Researchers utilize this tool to investigate ARHGAP17's roles in epithelial cell polarization, vesicle trafficking, and neuronal development, as well as its implications in diseases such as cancer metastasis and neurological disorders. Dysregulation of ARHGAP17 has been associated with disrupted cell-cell adhesion, aberrant cell migration, and pathological angiogenesis, highlighting its therapeutic potential. Studies also explore its interaction with the Hippo signaling pathway and polarity complexes like CRB3-PALS1-PATJ, emphasizing its cross-talk with critical developmental and homeostatic mechanisms. The availability of recombinant ARHGAP17 accelerates mechanistic insights into cytoskeletal regulation and disease pathogenesis.
