Quaternary structure of the calf testis follitropin receptor.
The quaternary structural relationships between subunits of the follitropin (FSH) receptor were determined through the use of the reversible, homobifunctional, chemical cross-linking reagent bis[2-(succinimidooxycarbonyloxy)ethyl]sulfone (BSOCOES) after formation of covalent 125I-azidobenzoyl-FSH-receptor subunit complexes by photoaffinity labeling. This experimental approach resulted in the fo...
متن کاملSolubilization and some characteristics of the follitropin receptor from calf testis.
Immature calf testes were found to be an unusually rich source of follitropin (FSH) receptors. Particulate fractions derived from such testes bound 32% of added biologically active radiolabeled human FSH (12”I-labeled hFSH) and had a binding capacity of 52 x lo-l4 mol/mg of protein. These values are considerably higher than those previously reported for FSH receptors in other types of beef or m...
متن کاملPurification of follitropin receptor from bovine calf testes.
Follitropin (FSH) receptors were solubilized from pure light membranes of bovine calf testis, using an optimum detergent to protein ratio of 0.01. The soluble FSH receptor fraction was gel filtered through Sepharose 6B to isolate an active fraction (6B-Fr-1) which behaved as a complex of FSH receptor and Gs protein. The 6B-Fr-1 was concentrated by ultrafiltration and further purified by sequent...
متن کاملThe Follitropin Receptor: Matching Structure and Function.
Follitropin, or follicle-stimulating hormone (FSH) receptor (FSHR), is a G protein-coupled receptor belonging to the glycoprotein hormone receptor family that plays an essential role in reproduction. Although its primary location is the gonad, the FSHR has also been reported in extragonadal tissues including bone, placenta, endometrium, liver, and blood vessels from a number of malignant tumors...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
