A short DNA sequence contained within all homeobox genes that codes for a specific amino acid sequence that binds to DNA and regulates transcription.

[homeo(tic gene) + box (from the fact that the DNA sequence is short and when written can be enclosed by a box on paper).]


(Genetics) genetics a particular sequence of DNA found in genes that regulate cell development

Four candidate markers, insulin-like growth factor 1 (IGF-1), human telomerase reverse transcriptase (hTERT), BLCA-4 and homeobox A13 (HOXA13) showed greater upregulation in stage Ta to T1 tumours than in stage >T1 tumours, with the greatest differential expression of BLCA-4 and HOXA13.
