the promotor of a gene is the region the regulates gene expression. So, tissue specific promotors only function in certian tissues of the body.

For example a protein called Nestin is only present in brain tissue. The reason why??? Although the nestin gene is present in every cell .. the Promotor is only ACTIVE in brain tissue (thereby allowing transcription (& translation) of nestin mRNA (to protein) in brain tissue)
