Oligosaccharide Assembly01:24

Oligosaccharide Assembly

Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.

Overview
Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
Proteoglycans01:05

Proteoglycans

Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Area of Science:

  • Immunology
  • Genetics
  • Molecular Biology

Background:

  • Mannose-binding lectin (MBL) is a serum protein produced mainly by the liver.
  • MBL initiates complement system activation via the lectin pathway by binding microbial and host cell structures.
  • Genetic variations in the MBL2 gene impact MBL protein stability and concentration.

Purpose of the Study:

  • To summarize the current molecular understanding of human MBL2 genetics.
  • To highlight the influence of MBL genetic variations on MBL serum concentrations.

Main Methods:

  • Review of existing epidemiological and molecular studies on MBL2 genetics.
  • Analysis of common variant alleles in MBL2 promoter and structural regions.

Main Results:

  • Common MBL2 variants significantly affect MBL serum concentrations.
  • These genetic variations are frequent in the human population, suggesting a dual role for MBL.
  • Proposed links between MBL levels and susceptibility/course of infectious, autoimmune, neoplastic, metabolic, and cardiovascular diseases are under investigation.

Conclusions:

  • Human MBL2 genetics plays a crucial role in determining MBL serum levels.
  • The frequent genetic variations underscore the complex and potentially dual function of MBL in health and disease.
  • Further research is needed to fully elucidate the impact of MBL genetic variations on diverse disease outcomes.
