RND1 (Rho family GTPase 1) is a member of the Rho GTPase family, which regulates cytoskeletal dynamics, cell polarity, migration, and intracellular signaling. Unlike classical Rho GTPases (e.g., RhoA, Rac1), RND1 lacks intrinsic GTPase activity, functioning as a constitutively active GTPase that modulates pathways by interacting with effectors like p190 RhoGAP and ROCK1. It plays context-dependent roles in cell adhesion, axon guidance, and tissue morphogenesis, with emerging links to cancer metastasis, neurological disorders, and vascular development. Dysregulation of RND1 is associated with altered cell motility and invasive phenotypes in tumors, as well as synaptic plasticity deficits.
Recombinant RND1 protein is produced via heterologous expression systems (e.g., E. coli, mammalian cells) to study its structure-function relationships and signaling mechanisms. Purification typically involves affinity tags (His, GST) followed by chromatography. Quality control employs SDS-PAGE, Western blotting, and functional assays (e.g., GTPase activity tests, effector binding studies). Its applications include crystallography for inhibitor design, in vitro reconstitution of signaling cascades, and screening for therapeutic compounds targeting RND1-driven pathologies. Challenges remain in maintaining post-translational modifications and resolving its pleiotropic roles across cell types. Current research focuses on deciphering RND1's crosstalk with other Rho GTPases and its potential as a biomarker or drug target.
