Sucrose non-fermenting 1-related protein kinases (SnRKs) comprise a major family of signaling genes in plants and are associated with metabolic regulation, nutrient utilization and stress responses. This gene family has been proposed to be involved in sucrose signaling. In the present study, we cloned three copies of the TaSnRK2.10 gene from bread wheat on chromosomes 4A, 4B and 4D. The coding ...

conclusions core-lds interaction may be an underlying molecular mechanism to induce liver steatosis in patients with hcv infection. this interaction is also crucial for efficient viral replication and persistence in infected cells. steatosis can also interfere with efficient standard interferon therapy treatment. management of steatosis should be considered along with standard care for achievin...

TAF 4b was first discovered as a tissue-specific subunit of TFIID in human B cells. The development of infertility in TAF 4b knockdown mice revealed its role in gonadal development. Its knockdown results in an increase in FSHβ expression, and affects the expression of several regulatory proteins involved in the FSHβ regulation in the LβT2 gonadotrope cell line. However, TAF 4b is not associated...

DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...

Cloned immortalized MC615 mouse chondrocytic cells were used to examine their capability to produce multiple types of matrix proteoglycans. Immunofluorescence staining indicated a uniform expression of aggrecan, biglycan and decorin by all cells. After culture with [35S]sulphate, proteo[35S]glycans secreted by the cells were found to elute in two peaks from a Sepharose CL-4B column. The first p...

The complete nucleotide sequences of the matrix protein (M) genes of parainfluenza virus types 4A and 4B (PIV-4A and -4B) were determined from cDNA of the mRNA, and found to be 1548 bases in length, exclusive of poly(A) sequences. The sequences contained a large open reading frame of 1146 nucleotides encoding 362 amino acids. A high degree of identity (96.1%) was observed between the amino acid...

Hepatitis C virus encodes a large polyprotein precursor that is proteolytically processed into at least 10 distinct products, in the order NH2-C-E1-E2-p7-NS2-NS3-NS4A-NS4B-NS5A-NS5B -COOH. A serine proteinase encoded in the N-terminal 181 residues of the NS3 nonstructural protein is responsible for cleavage at four sites (3/4A, 4A/4B, 4B/5A, and 5A/5B) in the nonstructural region. NS4A, a 54-re...

Members of the Flaviviridae encode a serine proteinase termed NS3 that is responsible for processing at several sites in the viral polyproteins. In this report, we show that the NS3 proteinase of the pestivirus bovine viral diarrhea virus (BVDV) (NADL strain) is required for processing at nonstructural (NS) protein sites 3/4A, 4A/4B, 4B/5A, and 5A/5B but not for cleavage at the junction between...

1. Postmitochondrial supernatants of rabbit reticulocyte lysates were chromatographed on heparin bound to Sepharose 4B, and the fraction retained on affinity columns was separated by subsequent gel filtration on Sepharose 4B into three fractions, two of them active in protein synthesis. 2. The heavier fraction sedimented at 40S and contained more than 10% RNA. This consisted predominantly of a ...
