<p>This entry represents a WD40/YVTN repeat-like domain. Both the WD40 and the YVTN repeated motifs consist of about 40 residues, and although they consist of distinct sequences, they do share a similar structure. Structurally, both the WD40 and the YVTN repeated motifs form seven-bladed propellers (although some members can contain eight blades), which consist of seven 4-stranded beta-sheets. </p><p>The WD40-type repeat domain is found in the beta-1 subunit of the signal-transducing G protein [<cite idref="PUB00023573"/>], in yeast Tup1 protein [<cite idref="PUB00024645"/>], in Groucho [<cite idref="PUB00025413"/>], in the yeast cell cycle protein Cdc4 [<cite idref="PUB00029039"/>] and in actin-interacting protein 1 [<cite idref="PUB00029204"/>].</p><p>The YVTN-type repeat domain is found in archaeal surface layer proteins (SLPs) that protect cells from extreme environments [<cite idref="PUB00014157"/>], in quinohemoprotein amine dehydrogenase (QHNDH) [<cite idref="PUB00022422"/>], and in methylamine dehydrogenase [<cite idref="PUB00012384"/>]. </p> WD40/YVTN repeat-like-containing domain
