Sterile alpha and TIR motif containing 1 Is an enzyme that in humans is encoded by the SARM1 gene. It is the most evolutionarily conserved member of the Toll/Interleukin receptor-1 (TIR) family. [5] [6] SARM1's TIR domain has intrinsic NADase enzymatic activity that is highly conserved from archaea, plants, nematode worms, fruit flies, and humans.
[2] [3] Each armadillo repeat is composed of a pair of alpha helices that form a hairpin structure. Multiple copies of the repeat form what is known as an alpha solenoid structure. Examples of proteins that contain armadillo repeats include β-catenin, Sarm1 , [4] α-importin, [5] plakoglobin, [6] adenomatous polyposis coli (APC), [7] and many ...
The toll-interleukin-1 receptor (TIR) homology domain is an intracellular signaling domain found in MyD88, SARM1, interleukin-1 receptors, toll receptors and many plant R proteins. It contains three highly conserved regions, and mediates protein-protein interactions between the toll-like receptors (TLRs) and signal-transduction components. TIR ...
Selective androgen receptor modulators (SARMs) are a class of drugs that selectively activate the androgen receptor in specific tissues, promoting muscle and bone growth while having less effect on male reproductive tissues like the prostate gland.
Ig-like domain is the part of receptor which is located extracellularly. There are minimal homologies in amino acid sequences of Ig-like domains between proteins of IL-1R family but they all show characteristic Ig-fold and two β-sheets joined together by disulfide bonds which form between cysteine residues.
The 3D crystal structure of the Smaug RNA-binding region shows a cluster of positively charged residues on the Smaug-SAM domain, which could be the RNA-binding surface. This electropositive potential is unique among all previously determined SAM-domain structures and is conserved among Smaug-SAM homologs.
Wallerian degeneration is an active process of degeneration that results when a nerve fiber is cut or crushed and the part of the axon distal to the injury (which in most cases is farther from the neuron's cell body) degenerates. [1]
Nicotinamide mononucleotide ("NMN" and "β-NMN") is a nucleotide derived from ribose, nicotinamide, nicotinamide riboside and niacin. [1] In humans, several enzymes use NMN to generate nicotinamide adenine dinucleotide (NADH). [1]
