Disease relevance of GUK1

  • HGS and GUK1 mRNA expression were chosen to be validated by quantitative RT-qPCR, however, only GUK1 had the differential expression confirmed between the adenomas and the metastasis of a pituitary carcinoma [1].
  • CONCLUSION: This trial demonstrated a significant treatment benefit of HDI versus GMK in terms of RFS and OS in melanoma patients at high risk of recurrence [2].
  • The E2696 trial was undertaken to evaluate the toxicity and other effects of the established adjuvant high-dose IFNalpha2b regimen in relation to immune responses to GMK and to evaluate the potential clinical and immunologic effects of the combined therapies [3].
  • Calorimetric and crystallographic analysis of the oligomeric structure of Escherichia coli GMP kinase [4].
  • A recessive mutation leading to vertebral ankylosis in zebrafish is associated with amino acid alterations in the homologue of the human membrane-associated guanylate kinase DLG3 [5].
 

High impact information on GUK1

  • Members of the MAGUK (membrane-associated guanylate kinase) protein family, like PSD-95, use multiple domains to cluster ion channels, receptors, adhesion molecules and cytosolic signaling proteins at synapses, cellular junctions, and polarized membrane domains [6].
  • The minute amount of residual activity in erythrocytes could represent a small amount of the AK2 isozyme, which has not been thought to be present in erythrocytes, or the activity of erythrocyte guanylate kinase with AMP substituting as substrate for GMP [7].
  • In hippocampal neurons, altered accumulation of PIP3 by overexpression of GAKIN constructs led to the loss of the axonally differentiated neurites [8].
  • Transport of PIP3 by GAKIN, a kinesin-3 family protein, regulates neuronal cell polarity [8].
  • Recombinant GAKIN and PIP3BP form a complex on synthetic liposomes containing PIP3 and support the motility of the liposomes along microtubules in vitro [8].
 

Chemical compound and disease context of GUK1

 

Biological context of GUK1

  • Evidence for the assignment of GUK 1 gene locus to 1q32 leads to q43 segment from gene dosage effect [11].
  • Specifically, the association of the Src homology 3 (SH3) domain and sequences situated between the SH3 and GUK domains with the GUK domain was found to interfere with GKAP binding [12].
  • Screening of a mouse thymus cDNA library yielded CARD11, a membrane-associated guanylate kinase (MAGUK) family member containing CARD, PDZ, SH3 and GUK domains [13].
  • Point mutations in either the putative beta2a SH3 or GK domains severely blunted modulation of recombinant L-type channels, showing the importance of both motifs for a functional alpha1-beta interaction [14].
  • Phosphorylation of the antiviral precursor 9-(1,3-dihydroxy-2-propoxymethyl)guanine monophosphate by guanylate kinase isozymes [15].
 

Anatomical context of GUK1

  • After 3 days starvation hepatic GMP kinase activity decreased slightly faster than total cytosol protein, while GMP synthetase activity was preferentially maintained [16].
  • The MAGUKs (membrane-associated guanylate kinase homologs) are a family of proteins that act as molecular scaffolds for signaling pathway components at the plasma membrane of animal cells [17].
  • Taken together, these results indicate that Lin-7 functions in tight junction formation by stabilizing its membrane-associated guanylate kinase binding partner PALS1 [18].
  • MAGUKs (membrane-associated guanylate kinase homologs) are proteins involved in cell junction organization, tumor suppression, and signalling [19].
  • Analysis of truncated forms of the PSD-95 indicated that the N-terminal PDZ-containing region localizes to caveolae, but the C-terminal region, containing the SH3 and the guanylate kinase domains does not [20].
 

Associations of GUK1 with chemical compounds

  • Although the function of the NH2-terminal PDZ domains is relatively well characterized, the function of the Src homology 3 (SH3) domain and the guanylate kinase-like (GK) domain in the COOH-terminal half of PSD-95 has remained obscure [21].
  • Genetic studies in non-vertebrates assigned two families of basolateral proteins, MAGUK (membrane-associated and guanylate kinase) and LAP (leucine-rich repeats and PDZ) proteins, to a common pathway crucial for the epithelial architecture and acting as a gatekeeper to malignancy [22].
  • The extreme C termini of alternatively spliced "b"-type Ca2+ pump isoforms resemble those of K+ channels and N-methyl-D-aspartate receptor subunits that interact with channel-clustering proteins of the membrane-associated guanylate kinase (MAGUK) family via PDZ domains [23].
  • Mg(2+) binding was considerably enhanced in functional high affinity complexes, such as observed between guanylate kinase and its bisubstrate inhibitor P(1)-(5'-guanosyl)-P(5)-(5'-adenosyl) pentaphosphate or with the tight nucleotide-binding protein p21(ras) and GDP [24].
  • For guanylate kinase (EC 2.7.4. 8), the transfer of HPO(3) between nucleotides was observed whenever a ternary complex with adenylate or guanylate nucleotides was formed [24].
 

Physical interactions of GUK1

 

Other interactions of GUK1

  • GUK1 and PEPC, known to be syntenic in man, were found to be asyntenic in MIM and could not be assigned [27].
  • We report the sequence of this human GK (GUK1) and a further refinement of its localization to 1q32-41, placing it in the same interval as USH2A [28].
  • Human discs large (hDlg) protein binds to protein 4.1R via a motif encoded by an alternatively spliced exon located between the SH3 and the C-terminal guanylate kinase-like domains [29].
  • CARMA proteins are scaffold molecules that contain a caspase recruitment domain and a membrane-associated guanylate kinase-like domain [30].
  • MAGI-2 is a multidomain scaffolding protein that contains nine potential protein-protein interaction modules, including 6 PDZ domains, 2 WW domains, and a guanylate kinase-like domain [31].
