Expression of the Drosophila src-related gene, Dsrc28C has been investigated at the protein level using monoclonal antibodies. This analysis has revealed that the Dsrc28C gene encodes two protein forms: a 66-kD doublet predicted from the sequence of a cDNA clone and an additional 55-kD form. The 66-kD protein doublet is observed first at the cellular blastoderm stage and is not detectable in em...

A 58-kD protein, identified in extracts of postsynaptic membrane from Torpedo electric organ, is enriched at sites where acetylcholine receptors (AChR) are concentrated in vertebrate muscle (Froehner, S. C., A. A. Murnane, M. Tobler, H. B. Peng, and R. Sealock. 1987. J. Cell Biol. 104:1633-1646). We have studied the 58-kD protein in AChR clusters isolated from cultured rat myotubes. Using immun...

A series of bulky organometallic and organic analogues the bromodomain (BRD) inhibitor (+)-JQ1 have been prepared. The most potent, N-[(adamantan-1-yl)methyl]-2-[(9S)-7-(4-chlorophenyl)-4,5,13-trimethyl-3-thia-1,8,11,12-tetraazatricyclo[8.3.0.02,6]trideca-2(6),4,7,10,12-pentaen-9-yl]acetamide, 2e, showed excellent potency with an KD=ca. 130 nm vs. BRD4(1) a ca. 2-fold selectivity over BRD4(2) (...

To the Editor: Approximately 5% of young children and 4% of adults have some type of adverse immune responses to foods in westernized countries. Mustard is a widely consumed spice that can trigger life-threatening IgE-mediated allergic reactions. Mustard is frequently consumed as a hidden allergen in foods, resulting in unexpected allergic reactions. It has been reported that more than 50% of p...

PURPOSE We conducted a study to determine which factors may be useful as predictive markers in identifying Kawasaki disease (KD) patients with a high risk of resistance to intravenous immunoglobulin (IVIG) and developing coronary artery lesions (CAL). METHODS We enrolled 287 patients in acute phase of KD at a single center. The demographic, clinical and laboratory data were collected retrospe...

A 94-kD protein that accumulates predominately in tomato (Ly-copersicon esculentum) fruit during ripening was purified, and antibodies specific for the purified protein were used to isolate cDNA clones from a red-ripe fruit cDNA library. A sequence analysis of these cDNAs and cross-reactivity of the 94-kD-specific antibodies to the soybean lipoxygenase (LOX) L-1, L-2, and L-3 proteins and soybe...

We have isolated a protein factor from Xenopus eggs that promotes microtubule assembly in vitro. Assembly promotion was associated with a 215-kD protein after a 1,000-3,000-fold enrichment of activity. The 215-kD protein, termed Xenopus microtubule assembly protein (XMAP), binds to microtubules with a stoichiometry of 0.06 mol/mol tubulin dimer. XMAP is immunologically distinct from the Xenopus...

in the present study, we investigated total cell protein patterns of ten isolates of trichophyton rubrum by sds-page on 12.5% polyacrylamide resolving gels. twenty-two protein bands were detected with molecular weights in the range of 23.2 to 131.8 kd. proteins of 23.2, 25.4, 26.7, 28.2, 30.2, 33.1, 34.7, 38,41.7, 47.9, 52.5, 56.2, 61.7, 67.6, 70.8, 75.9, 80, 84.1, 93.3, 102.3, 114.8, 131.8 wer...

Small nuclear ribonucleoprotein particles containing the five major nucleoplasmic snRNAs U1, U2, U4, U5 and U6 as well as two smaller sized snRNAs were purified from broad bean nuclear extracts by anti-m3G, monoclonal antibody, immunoaffinity chromatography. We have so far defined 13 polypeptides of approximate mol. wts. of 11 kd, 11.5 kd, 12.5 kd, 16 kd, 17 kd, 17.5 kd, 18.5 kd, 25 kd (double ...
