Electrophoretic mobility shift assay

Electrophoretic mobility shift assay is an experiment that uses electricity to move macromolecules, like proteins, through a gel matrix to cause a separation between the different macromolecules based on size. Like a car battery, the negative and positive ends are on opposite sides of the electrophoretic mobility shift assay, or gel shift assay. This causes electricity to attract the macromolecules based on charge.

Electrophoretic mobility shift assay

They found that CTNS encodes an integral membrane protein, which they designated cystinosin, that has features of a lysosomal membrane protein.

CTNS, a putative cystine transporter, contains amino acids and 7 transmembrane domains.

This region contains an Sp-1 regulatory element at positions to which, as shown by electrophoretic mobility shift assays, binds Sp The most common mutation was a kb deletion Of 82 alleles bearing the kb deletion, 38 derived from Germany, 28 from the British Isles, and 4 from Iceland.

The 18 new mutations identified in this study included the first reported missense mutation, 2 in-frame deletions, and mutations in patients of African American, Mexican, and Indian ancestry.

CTNS mutations were spread throughout the leader sequence, transmembrane, and nontransmembrane regions. According to a cystinosis clinical severity score, homozygotes for the kb deletion and for WX had average disease, whereas mutations involving the first amino acids prior to transmembrane domains were associated with mild disease.

By Northern blot analysis, CTNS was not expressed in patients homozygous for the kb deletion but was expressed in all 15 other patients tested. Structure predictions suggested that cystinosin is a novel integral lysosomal membrane protein. They screened patients with infantile nephropathic cystinosis, those with late-onset cystinosis, and patients whose phenotype did not fit the classic definitions.

They identified 23 different mutations in the CTNS gene, 14 of which were novel. Of 25 patients with infantile nephropathic cystinosis, 12 had 2 severely truncating mutations, consistent with a loss of functional protein, and 13 had missense or in-frame deletions, which would result in disruption of transmembrane domains and loss of protein function.

Mutations identified in 2 late-onset patients see, e. For 3 patients, the age of onset of cystinosis was under 7 years, but the course of the disease was milder than the infantile nephropathic form. This suggested that the missense mutations identified in these individuals see, e.

As indicated earlier, identification of the CTNS gene was facilitated by the detection of deletions spanning the cystinosis locus in affected individuals. Two types of deletions were detected, one of approximately 65 kb, which was found in homozygous state in nearly one-third of cystinotic individuals, and a smaller one of 9.

Both the larger and the smaller deletion span the 5-prime end of the CTNS gene, covering exons 1 to 10 and 1 to 3, respectively; STS analysis indicated that the larger deletion was the same size in all patients.

This type of mechanism suggested that the deletion of approximately 65 kb is not a recurrent mutation, and the results confirmed that it is identical in all patients. Haplotype analysis showed that this large deletion is due to a founder effect that occurred in a white individual, and that it probably arose in the middle of the first millennium.Electrophoretic mobility shift assay An electrophoretic mobility shift assay (EMSA), also referred as a gel shift assay, gel mobility shift assay, band shift assay, or gel retardation assay, is a common technique used to study protein - DNA or protein- RNA interactions.

BackgroundDespite evidence that genetic factors contribute to the duration of gestation and the risk of preterm birth, robust associations with genetic variants have not been identified. We used. An electrophoretic mobility shift assay (EMSA) or mobility shift electrophoresis, also referred as a gel shift assay, gel mobility shift assay, band shift assay, or gel retardation assay, is a common affinity electrophoresis technique used to study protein–DNA or protein–RNA interactions. This procedure can determine if a protein or mixture of proteins is capable of binding to a given DNA.

Electrophoretic mobility shift assay

The electrophoretic mobility shift assay (EMSA), also known as gel retardation assay, is a regularly used system to detect protein-nucleic acid interactions.

It was originally developed with the aim of quantifying interactions between DNA and proteins (Fried & Crothers, ;.
