The GCR2 gene is required for the transcriptional activation of retrotransposon Ty2-917 in Saccharomyces cerevisiae.
Ty2 retrotransposons are the mobile genetic elements of the yeast Saccharomyces cerevisiae. Transcriptional regulation of Ty2-917 requires a complex set of cis acting elements which are located both upstream and downstream of the transcription initiation site. Previously, the glycolysis regulatory protein Gcr1p has been identified as the major transcriptional regulator of Ty2-917. Gcr1p is a DN...
متن کاملSquamous cell carcinoma of lung with unusual site of metastasis
Background: Lung cancer ranks among the most common and most lethal malignancies worldwide. Once vascular or lymphatic invasions occur, metastatic dissemination to distant sites is common. Bone, liver, adrenals, and brain are the most frequent sites of the distant disease. In this study we present a case of squamous cell carcinoma of lung with metastasis of the left knee bursa.Case presentation...
متن کاملDe-Novo Presentation of Histoid Leprosy on an Unusual Site
Histoid Leprosy (HL) is a rare variant of Lepromatous Leprosy, occurring in long-standing cases, mostly in a background of acquired drug resistance. Patients usually present with sudden onset multiple nodules and plaques, most often involving the skin and subcutaneous tissue of trunk and lower limbs. Here we report an unusual case of de novo (without any history of prior anti-leprotic therapy) ...
متن کاملAn unusual orientation for Tyr75 in the active site of the aspartic proteinase from Saccharomyces cerevisiae.
The structures of the native Saccharomyces cerevisiae proteinase A have been solved by molecular replacement in the monoclinic and trigonal crystal forms and refined at 2.6-2.7A resolution. These structures agree overall with those of other uninhibited aspartic proteinases. However, an unusual orientation for the side chain of Tyr75, a conserved residue on the flexible "flap" that covers the ac...
