Here we describe the 3.2 Å cryo-EM structure of human DEC-205, thereby illuminating the structure of the mannose receptor protein family. (uci.edu)

One cluster includes kinases in catalytically active conformations. (rcsb.org)

The presence of both protein interaction domains (ARM, ANK, LRR and WD40) and the enzymatic domains (ROC and MAPK) within LRRK2 suggests that this protein may serve as a scaffold for assembly of a multiprotein complex and act as a central integrator of multiple signaling pathways. (irispublishers.com)

Typically, kinases adopt at most one of the inactive conformations in available X-ray structures, implying that one of the conformations is preferred for many kinases. (rcsb.org)
We recommend using this workflow before setting up and executing FEP+ calculations, especially for flexible protein structures. (nature.com)

While the catalytic domain of these kinases is highly conserved , the sequence variation that is observed in the kinome (the subset of genes in the genome that encode kinases) provides for recognition of distinct substrates. (cloudfront.net)
A beta-hairpin comprising the nuclear localization sequence sustains the self-associated states of nucleosome assembly protein 1. (colorado.edu)

These proteins contain two related domains known as the chromo- and the chromoshadow-domain. (cipsm.de)
On just about every of those ORFs, we ran a Reverse PSI BLAST towards all protein domains through the Conserved Domain Database. (dub-signal.com)

Drug discovery that specifically targeted the ATP binding site of a single kinase was regarded as quite a challenging task since hundreds of protein kinases were known in the human genome. (wikipedia.org)
RIOK2 is a typical kinase implicated in multiple human cancers. (cancer-research-network.com)
We stained the mem branes utilizing the antibodies against HCMV proteins and human actin inside the presence of a chemiluminescent sub strate, and ana lyzed the stained membranes by using a STORM840 phosphorimager. (dub-signal.com)
The SurvivinGp localizes like a standard CPC protein capable of interacting with human CPC members To evaluate the functional properties on the guinea pig Survivin protein with people of its human homologue, we to begin with examined its localization while in mitosis. (mirnamimic.com)
In particular, human organic cation transporter 2 (hOCT2) and multidrug and toxin extrusion proteins 1 and 2-K (hMATE1/2-K) likely mediate renal secretion of mIBG, whereas hOCT1 and hOCT3 may contribute to mIBG uptake into normal tissues such as the liver, salivary glands, and heart.

A new class of RIPK2 kinase/NOD signaling inhibitors based on a 3,5-diphenyl-2-aminopyridine scaffold was developed. (ox.ac.uk)
