ho·me·o·box

(hō'mē-ō-boks),
A highly conserved DNA sequence of about 180 base pairs near the 3' end of specific homeotic genes; it encodes a DNA-binding domain that allows the homeobox proteins to bind to and regulate gene expression in development.
Synonym(s): homeodomain

Pribnow box

a NUCLEOTIDE sequence found in prokaryotic PROMOTERS that is required for initiation of TRANSCRIPTION. It allows the RNA POLYMERASE to position itself correctly at the transcription start site on DNA. The CONSENSUS SEQUENCE is 5′-TATAAT-3′.

Sometimes it is called the -10 sequence, because of its location UPSTREAM of the transcription start. The Pribnow box was named after D Pribnow, who first pointed out such sequences.

Pribnow box - a highly conserved DNA sequence of about 180 base pairs near the 3' end of specific homeotic genes.

Pribnow box

the sequence of five to 10 bases in the promotor region of Escherichia coli genes. It is a variant of a basic sequence TATAATG. See also tata box.
