Alternative exon splicing and differential expression in pancreatic islets reveals candidate genes and pathways implicated in early diabetes development.
Title: Alternative exon splicing and differential expression in pancreatic islets reveals candidate genes and pathways implicated in early diabetes development.
Galectin-2 (Gal-2) residues near cysteine residues C57 experienced significant chemical shift changes following S-nitrosylation.
Title: Structural mechanisms for the S-nitrosylation-derived protection of mouse galectin-2 from oxidation-induced inactivation revealed by NMR.
analysis of the effect of low-temperature plasma on the expression of galectin-1, -2, and -3 in the healing skin compared with those of electrocoagulation conducted with a high-frequency electrical coagulator
Title: Galectin expression in healing wounded skin treated with low-temperature plasma: Comparison with treatment by electronical coagulation.
Therefore, Cys(57) is suggested to be responsible for oxidative inactivation of the mGal-2 protein, and protection of the sulfhydryl group of the Cys(57) in mGal-2 by S-nitrosylation is likely important for maintaining mGal-2 protein function in an oxidative environment such as the gastrointestinal tract.
Title: Identification of the cysteine residue responsible for oxidative inactivation of mouse galectin-2.
Studies of specific knock-out mice show that galectin-2 acts through the CD14/toll-like receptor (TLR)-4 pathway. It leads to increased CD40-positive and reduced CD206-positive macrophages around remodeling collateral arteries.
Title: Galectin-2 induces a proinflammatory, anti-arteriogenic phenotype in monocytes and macrophages.
Gal-2 oxidation by H2O2 resulted in the loss of sugar-binding ability, while S-nitrosylation prevented H2O2-inducted inactivation, presumably by protecting the Cys residue(s) in the protein.
Title: S-nitrosylation of mouse galectin-2 prevents oxidative inactivation by hydrogen peroxide.
In normal murine skin, low levels of galectin-2 messenger RNA are detected.
Title: Galectin-2 suppresses contact allergy by inducing apoptosis in activated CD8+ T cells.
Galectin-2 was present in nuclei of murine 3T3 fibroblasts.
Title: Human galectin-2: nuclear presence in vitro and its modulation by quiescence/stress factors.
A comparative profiling has been started in the mouse as a model organism, combining sequence analysis, expression patterns and structural features in the cases of the homodimeric galectins-1, -2 and -7.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
