Androgen specificity of a response unit upstream of the human secretory component gene is mediated by differential receptor binding to an essential androgen response element.

Abstract excerpt

The expression of secretory component (SC), the epithelial receptor for poly-immunoglobulins, is regulated in a highly tissue-specific manner. In several tissues, e.g. lacrimal gland and prostate, SC synthesis is enhanced by androgens at the transcriptional level. In this study, we describe the presence of an androgen response unit, located 3.3 kb upstream of the sc transcription initiation site and containing...
