Comments

FB elements have a consensus structure: each begins with a 470bp of non-repetitive sequence followed by a set of 154bp blocks. Each block starts with the sequence CTC and is composed of five almost identical repeats of 32bp. When NOF elements are present within FB elements, they are always found after the sequence TCCT in the second repeat of a block. It is possible that the composite FB-NOF is the complete transposable element.

None of the NOF elements found are complete, and all but one are cut at 163bp from the beginning.

Ectopic pairing in polytene chromosomes between different NOF sites is frequently seen.

The distribution of NOF sequences in a number of different strains has been studied. NOF sequences are almost invariably associated with FB element sequences. These composite FB-NOF elements are usually rare, many strains lack the composite element or have only one copy of it. The NOF region associated with Tp(1;2)TE35B has been sequenced. NOF could potentially encode a 120kD polypeptide.

Complete FB transposable elements encode a novel protein found in D.melanogaster.
