Rhotekin is a protein that in humans is encoded by the RTKN gene.{{cite journal | vauthors = Jang W, Weber JS, Harkins EB, Meisler MH | title = Localization of the rhotekin gene RTKN on the physical maps of mouse chromosome 6 and human chromosome 2p13 and exclusion as a candidate for mnd2 and LGMD2B | journal = Genomics | volume = 40 | issue = 3 | pages = 506–7 |date=May 1997 | pmid = 9073523 | doi = 10.1006/geno.1996.4593 }}{{cite journal | vauthors = Reynaud C, Fabre S, Jalinot P | title = The PDZ protein TIP-1 interacts with the Rho effector rhotekin and is involved in Rho signaling to the serum response element | journal = J Biol Chem | volume = 275 | issue = 43 | pages = 33962–8 |date=Nov 2000 | pmid = 10940294 | doi = 10.1074/jbc.M000465200 | doi-access = free }}{{cite web | title = Entrez Gene: RTKN rhotekin| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=6242}}

This gene encodes a scaffold protein that interacts with GTP-bound Rho proteins. Binding of this protein inhibits the GTPase activity of Rho proteins. This protein may interfere with the conversion of active, GTP-bound Rho to the inactive GDP-bound form by RhoGAP. Rho proteins regulate many important cellular processes, including cytokinesis, transcription, smooth muscle contraction, cell growth and transformation. Dysregulation of the Rho signal transduction pathway has been implicated in many forms of cancer. Alternative splicing results in multiple transcript variants encoding different isoforms.
