What does RISC stand for and what is the function of RISC?

RISC (reduced instruction set computer) is a microprocessor that is designed to perform a smaller number of types of computer instructions so that it can operate at a higher speed (perform more millions of instructions per second, or MIPS).

What is RISC and what is its function in eukaryotic gene regulation?

RNA-induced silencing complex (RISC) is one of the basic eukaryotic cellular machinery which plays a pivotal role in post-transcriptional gene regulation. The method of gene silencing using small interfering RNAs and miRNAs has become major tool in molecular biology and genetic engineering.

What is the function of the enzyme Dicer and RISC complex?

Dicer facilitates the activation of the RNA-induced silencing complex (RISC), which is essential for RNA interference. RISC has a catalytic component Argonaute, which is an endonuclease capable of degrading messenger RNA (mRNA).

What is in the RISC complex?

The cytoplasmic RNA-induced silencing complex (RISC) contains dsRNA binding proteins, including protein kinase RNA activator (PACT), transactivation response RNA binding protein (TRBP), and Dicer, that process pre-microRNAs into mature microRNAs (miRNAs) that target specific mRNA species for regulation.

What does RISC mean?

Reduced Instruction Set Computer
RISC (Reduced Instruction Set Computer) A processor architecture that shifts the analytical process of a computational task from the execution or runtime to the preparation or compile time. By using less hardware or logic, the system can operate at higher speeds.

Do humans have RISC?

Ago proteins bind small RNAs, 19–30 nt in length, which are used to guide the RISC to cognate RNA transcripts through base-pairing interactions. The human genome encodes four Ago proteins and four Ago-related proteins called Piwi (3). Thus, there are potentially at least eight distinct types of RISC activity in humans.

What is RISC in biology?

RNA-induced silencing complex, or RISC, is a multiprotein complex that incorporates one strand of a small interfering RNA (siRNA) or micro RNA (miRNA). RISC uses the siRNA or miRNA as a template for recognizing complementary mRNA.

What are the functions of RISC complex in the RNA interference pathway?

The most understood function of RISC is degradation of target mRNA which reduces the levels of transcript available to be translated by ribosomes. The endonucleolytic cleavage of the mRNA complementary to the RISC’s guide strand by Argonaute protein is the key to RNAi initiation.

What is the role of RISC architecture in compiler?

RISC helps and supports few simple data types and synthesizes complex data types. RISC uses the Harvard memory model means it is Harvard Architecture. A compiler is used to perform the conversion operation means converting a high-level language statement into the code of its form.

What is the role of RISC in RNA interference?

RNA-induced silencing complex, or RISC, is a multiprotein complex that incorporates one strand of a small interfering RNA (siRNA) or micro RNA (miRNA). RISC uses the siRNA or miRNA as a template for recognizing complementary mRNA. When it finds a complementary strand, it activates RNase and cleaves the RNA.
