Repeat-induced point mutation (RIP) in Neurospora results in inactivation of duplicated DNA sequences. RIP is thought to provide protection against foreign elements such as retrotransposons, only one of which has been found in N. crassa. To examine the role of RIP in nature, we have examined seven N. crassa strains, identified among 446 wild isolates scored for dominant suppression of RIP. The ...
The death-domain kinase RIP (receptor-interacting protein) is an important effector of tumour necrosis factor (TNF) signalling and is essential for TNF-induced nuclear factor-kappaB activation. However, the function of RIP in the TNF-induced activation of mitogen-activated protein kinases (MAPKs) has not been fully investigated. In this report, using Rip null (Rip(-/-)) mouse fibroblast cells, ...
The null space property (NSP) and the restricted isometry property (RIP) are two properties which have received considerable attention in the compressed sensing literature. As the name suggests, NSP is a property that depends solely on the null space of the measurement procedure and as such, any two matrices which have the same null space will have NSP if either one of them does. On the other h...
abrin known as ribosome inactivating protein’s (rip) it is a high cytotoxic plant protein. high lethality and low cost and easy access to plant and seeds lead to this toxin used in crimes and terrorist acts. because obtaining purified toxins requires advanced laboratory equipment and complex procedures, so, it appears that the perpetrators of such crimes use crude extracts. as a result, remaini...
RIP (repeat-induced point mutation) efficiently mutates repeated sequences in the sexual phase of the Neurospora crassa life cycle. Nevertheless, an active LINE-like retrotransposon, Tad, was found in a N. crassa strain from Adiopodoumé. The possibility was tested that Tad might be resistant to RIP, or that the Adiopodoumé strain might be incompetent for RIP. Tad elements derived from the Adiop...
Rat insulin promoter (RIP)-expressing neurons in the hypothalamus control body weight and energy homeostasis. However, genetic approaches to study the role of these neurons have been limited by the fact that RIP expression is predominantly found in pancreatic β-cells, which impedes selective targeting of neurons. To define the function of hypothalamic RIP-expressing neurons, we set out to acute...
Duplicate DNA sequences in the genome of Neurospora crassa can be detected and mutated in the sexual phase of the life cycle by a process termed RIP (repeat-induced point mutation). RIP occurs in the haploid nuclei of fertilized, premeiotic cells before fusion of the parental nuclei. Both copies of duplications of gene-sized sequences are affected in the first generation at frequencies of appro...
Receptor-interacting protein (RIP) plays a critical role in tumor necrosis factor alpha (TNF-alpha)-induced NF-kappaB activation. However, the mechanism by which RIP mediates TNF-alpha-induced signal transduction is not fully understood. In this study, we reconstituted RIP-deficient Jurkat T cells with a fusion protein composed of full-length MEKK3 and the death domain of RIP (MEKK3-DD). In the...
We make a trivial modification to the elegant analysis of Garg and Khandekar (Gradient Descent with Sparsification ICML 2009) that replaces the standard Restricted Isometry Property (RIP), with another RIP-type property (which could be simpler than the RIP, but we am not sure; it could be as hard as the RIP to check, thereby rendering this little writeup totally worthless).
