Sock hop

A sock hop or sox hop, often also called a record hop or just a hop, was an informal sponsored dance event for teenagers in mid-20th-century North America, featuring popular music.

History

Sock hops were held as early as 1944 by the American Junior Red Cross to raise funds during World War II. They then became a fad among American teenagers in 1948. Sock hops were commonly held at high schools and other educational institutions, often in the school gym or cafeteria. The term came about because dancers were required to remove their hard-soled shoes to protect the varnished floor of the gymnasium. The music at a sock hop was usually played from vinyl records, sometimes presented by a disc jockey. Occasionally there were also live bands. The popularity of sock hops coined the phrase Bobby soxer; which described the fans of Traditional pop music.

In later years, "hops" became strongly associated with the 1950s and early rock and roll.Danny and the Juniors sang "At the Hop" in 1957, which named many popular dances and otherwise documented what happened at a hop. In subsequent decades, with the widespread popularity of sneakers and other types of indoors-only shoes, the practice of removing shoes was dropped. The term then came to be applied more generally to any informal dance for teenagers.

HOP!

Société HOP! is the brand name of the regional flights operated by subsidiaries of Air France. Its flight are operated by Airlinair, Brit Air and Régional under the HOP! brand. The new brand offers daily flights to 50 French and European destinations. Its head office is in the Parc tertiaire Silic in Rungis in Greater Paris.

History

The new airline brand was created to better compete with the low-cost airlines which have taken a significant market share of Air France's regional routes. Régional Compagnie Aérienne Européenne, Brit Air and Airlinair operate a combined total of 103 aircraft.

The airline is acquiring 5 ATR 72-600 aircraft in 2015 as replacements for its older ATR 72-500s.

Hop (protein)

Hop, occasionally written HOP, is an abbreviation for Hsp70-Hsp90 Organizing Protein. It functions as a co-chaperone which reversibly links together the protein chaperones Hsp70 and Hsp90.

Hop belongs to the large group of co-chaperones, which regulate and assist the major chaperones (mainly heat shock proteins). It is one of the best studied co-chaperones of the Hsp70/Hsp90-complex. It was first discovered in yeast and homologues were identified in human, mouse, rat, insects, plants, parasites, and virus. The family of these proteins is referred to as STI1 (stress inducible protein) and can be divided into yeast, plant, and animal STI1 (Hop).

Synonyms

Gene

The gene for human Hop is located on chromosome 11q13.1 and consists of 14 exons.

Structure

STI proteins are characterized by some structural features: All homologues have nine tetratricopeptide repeat (TPR) motifs, that are clustered into domains of three TPRs. The TPR motif is a very common structural feature used by many proteins and provides the ability of directing protein-protein interactions. Crystallographic structural information is available for the N-terminal TPR1 and the central TPR2A domains in complex with Hsp90 resp. Hsp70 ligand peptides.
