Two members of the CDK5 and ABL enzyme substrate (CABLES) family, CABLES1 and CABLES2, share a highly homologous C-terminus. They interact and associate with cyclin-dependent kinase 3 (CDK3), CDK5, and c-ABL. CABLES1 mediates tumor suppression, regulates cell proliferation, and prevents protein degradation. Although Cables2 is ubiquitously expressed in adult mouse tissues at RNA level, the role of CABLES2 in vivo remains unknown. Here, we generated bicistronic Cables2 knock-in reporter mice that expressed CABLES2 tagged with 3×FLAG and 2A-mediated fluorescent reporter tdTomato. Cables2-3×FLAG-2A-tdTomato (Cables2Tom) mice confirmed the expression of Cables2 in various mouse tissues. Interestingly, high intensity of tdTomato fluorescence was observed in the brain, testis and ovary, especially in the corpus luteum. Furthermore, immunoprecipitation analysis using the brain and testis in Cables2Tom/Tom revealed interaction of CABLES2 with CDK5. Collectively, our new Cables2 knock-in reporter model will enable the comprehensive analysis of in vivo CABLES2 function. 相似文献

Estrogen sulfotransferase (SULT1E) mainly catalyzes the sulfation of estrogens, which are known to prevent the pathogenesis of atherosclerosis. Recently, we found that peptides with a YKDG sequence specifically bind to oxidized low‐density lipoprotein (Ox‐LDL), which plays a major role in the pathogenesis of atherosclerosis. Here, we investigated the interaction between human SULT1E1 (hSULT1E1), which has a YKEG sequence (residues 61–64) unlike other human SULTs, and Ox‐LDL. Results from polyacrylamide gel electrophoresis and western blotting demonstrated that hSULT1E1 specifically binds to Ox‐LDL and its major lipid component (lysophosphatidylcholine; LPC), and platelet‐activating factor (PAF), which bears a marked resemblance to LPC in terms of structure and activity. Moreover, an N‐terminally fluorescein isothiocyanate (FITC)‐labeled decapeptide (MIYKEGDVEK; FITC‐hSULT1E1‐P10) corresponding to residues 59–68 of hSULT1E1 specifically binds to Ox‐LDL, LPC, and PAF. Unveiling the specific interaction between hSULT1E1 and Ox‐LDL, LPC, and PAF provides important information regarding the mechanisms underlying various diseases caused by Ox‐LDL, LPC, and PAF, such as atherosclerosis. In addition, FITC‐hSULT1E1‐P10 could be used as an efficient fluorescent probe for the detection of Ox‐LDL, LPC, and PAF, which could facilitate the mechanistic study, identification, diagnosis, prevention, and treatment of atherosclerosis. 相似文献

In this study, the anti–severe acute respiratory syndrome coronavirus-2 (anti-SARS-CoV-2) activity of mycophenolic acid (MPA) and IMD-0354 was analyzed. These compounds were chosen based on their antiviral activities against other coronaviruses. Because they also inhibit dengue virus (DENV) infection, other anti-DENV compounds/drugs were also assessed. On SARS-CoV-2-infected VeroE6/TMPRSS2 monolayers, both MPA and IMD-0354, but not other anti-DENV compounds/drugs, showed significant anti-SARS-CoV-2 activity. Although MPA reduced the viral RNA level by only approximately 100-fold, its half maximal effective concentration was as low as 0.87 µ m , which is easily achievable at therapeutic doses of mycophenolate mofetil. MPA targets the coronaviral papain-like protease and an in-depth study on its mechanism of action would be useful in the development of novel anti-SARS-CoV-2 drugs. 相似文献

Members of the homeodomain-interacting protein kinase (HIPK) family are involved in various intracellular regulatory mechanisms. The present study focused on clarifying the functions of HIPK family members in ocular organization during late embryogenesis. HIPK1 and HIPK2 were expressed in the inner retina during late embryogenesis. Hipk1+/−Hipk2−/− mice had a greater frequency of small eyes with a lens deficiency and abnormally laminated and thickened retinas than did wild-type littermates. These data indicate that Hipk1 and Hipk2 are involved in regulation of eye size, lens formation and retinal lamination during late embryogenesis. 相似文献

In order to understand the morphogenesis-inducing mechanism of Ulva pertusa by symbiotic bacteria, we observed the requisite conditions of bacteria for attachment to U. pertusa for algal morphogenesis. Non-morphogenesis-inducing bacterial mutants derived by ultraviolet irradiation did not attach onto
the surface of this alga. Scanning electron microscopic observation during the process of morphogenesis in U. pertusa revealed a network-like structure formed on the algal surface within 1 week after application of bacteria. The bacteria attached
onto the alga after 2 weeks of incubation. After this attachment process the morphologic change was observed in U. pertusa.
