The coi1-16 Mutant Harbors a Second Site Mutation Rendering PEN2 Nonfunctional

Functional recovery of troponin I in a Drosophila heldup mutant after a second site mutation.

To identify proteins that interact in vivo with muscle components we have used a genetic approach based on the isolation of suppressors of mutant alleles of known muscle components. We have applied this system to the case of troponin I (TnI) in Drosophila and its mutant allele heldup2 (hdp2). This mutation causes an alanine to valine substitution at position 116 after a single nucleotide change...

the impact of training on second language writing assessment: a case of raters’ biasedness

چکیده هدف اول این تحقیق بررسی تأثیر آموزش مصحح بر آموزش گیرندگان براساس پایایی نمره های آنها در پنج بخش شامل محتوا ، سازمان ، لغت ، زبان و مکانیک بود. هدف دوم این بود که بدانیم آیا تفاوتهای بین آموزشی گیرندگان زن و مرد در پایایی نمرات آنها وجود دارد. برای بررسی این موارد ، ما 90 دانشجو در سطح میانه (متوسط) که از طریق تست تعیین سطح شده بودند انتخاب شدند. بعد از آنها خواستیم که درباره دو موضوع ا...

A T3587G germ-line mutation of the MDR1 gene encodes a nonfunctional P-glycoprotein.

The human multidrug resistance gene 1 (MDR1) encodes a plasma membrane P-glycoprotein (P-gp) that functions as an efflux pump for various structurally unrelated anticancer agents. We have identified two nonsynonymous germ-line mutations of the MDR1 gene, C3583T MDR1 and T3587G MDR1, in peripheral blood cell samples from Japanese cancer patients. Two patients carried the C3583T MDR1 allele that ...

UMSCC38 cells amplified at 11q13 for the folate receptor synthesize a mutant nonfunctional folate receptor.

Some cells accumulate folate via a receptor-coupled process termed potocytosis. The folate receptor, a glycosyl phosphatidylinositol anchored M(r) 38,000-39,000 glycoprotein, is coded for by at least two genes (FR alpha and FR beta) at 11q13. The karyotype of UMSCC38, a human squamous cell carcinoma cell line, suggests that it may contain multiple copies of the folate receptor gene(s). Southern...
