Technical Data
AIBZIP (CREB3L4, Cyclic AMP-responsive Element-binding Protein 3-like Protein 4, cAMP-responsive Element-binding Protein 3-like Protein 4, Androgen-induced Basic Leucine Zipper Protein, AIbZIP, Attaching to CRE-like 1, ATCE1, Cyclic AMP-responsive Element
Androgen-induced basic leucine zipper (AIBZIP)is a transcription factor. AIbZIP is a 395aa protein with homology to cyclic AMP-responsive element binding protein/activating transcription factor. It contains an NH(2)-terminal activation domain, a central bZIP domain, and a COOH-terminal transmembrane domain. Immunoreactive AIbZIP protein has been detected in the cytoplasm of prostatic luminal epithelial cells; full-length AIbZIP-GFP fusion proteins are localized in the cytoplasm of LNCaP cells, while a truncated form of AIbZIP lacking the putative transmembrane domain was exclusively nuclear. AIbZIP is expressed at higher levels in cancerous prostate cells compared with noncancerous prostate cells.

Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.
