GTP binding protein

KIR, GTP-Binding Protein, KIR3DL1
Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response.

Papers on KIR
Skin Cancer Risk Is Modified by KIR/HLA Interactions That Influence the Activation of Natural Killer Immune Cells.
Nelson et al., Minneapolis, United States. In Cancer Res, Feb 2016

Exploring the Role of Killer Cell Immunoglobulin-Like Receptors and Their HLA Class I Ligands in Autoimmune Hepatitis.
Carcassi et al., Cagliari, Italy. In Plos One, Dec 2015
Additionally, the low frequency of the KIR-ligand combinations KIR3DL1/HLA-Bw4 and KIR2DL3/HLA-C1 coupled to the high frequency of the HLA-C2 high affinity ligands for KIR2DS1 could contribute to unwanted NK cell autoreactivity in AIH-1.
Targeting renal epithelial channels for the control of insect vectors.
Denton et al., Ithaca, United States. In Tissue Barriers, Oct 2015
Three small molecules were identified in high throughput screens that 1) block renal inward rectifier potassium (Kir) channels of Aedes aegypti expressed in HEK cells and Xenopus oocytes, 2) inhibit the secretion of KCl but not NaCl in isolated Malpighian tubules, and after injection into the hemolymph, 3) inhibit KCl excretion in vivo, and 4) render mosquitoes flightless or dead within 24h.

Inwardly rectifying potassium (Kir) channels exhibit an asymmetrical conductance at hyperpolarization (high conductance) compared to depolarization (low conductance).
Natural killer cell maturation markers in the human liver and expansion of an NKG2C+KIR+ population.
Khakoo et al., Southampton, United Kingdom. In Lancet, Mar 2015
FINDINGS: Frequencies of NK cell precursors were similar in the liver and the blood (0·91% [0·62-3·26] vs 0·87 [0·41-1·52]); however, expression of all later markers of maturity were reduced including CD16 (47% [40·4-61·4] vs 88·7 [82·2-93·2], p<0·0001), CD57 (30·7% [25·0-53·9] vs 73·4 [70·4-87·6], p=0·0003), and KIR (11·2% [7·5-14·5] vs 26·7 [17·3-30·8], p<0·0001).
