Anti-CREB3L2 / Cyclic AMP-responsive element-binding protein 3-like protein 2

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml. CREB3L2 antibody detects Cyclic AMP-responsive element-binding protein 3-like protein 2, a transcription factor that regulates endoplasmic reticulum (ER) stress response and secretory pathway gene expression. The UniProt recommended name is Cyclic AMP-responsive element-binding protein 3-like protein 2 (CREB3L2). This ER membrane-bound transcription factor modulates secretion, collagen synthesis, and stress adaptation through transcriptional control of Golgi and ER-resident proteins.Functionally, CREB3L2 antibody identifies a 520-amino-acid protein anchored in the ER membrane via a C-terminal transmembrane domain. Upon ER stress or secretory stimulation, the N-terminal cytosolic fragment of CREB3L2 is cleaved and translocates to the nucleus, where it binds CRE-like sequences in target promoters to activate genes related to vesicle trafficking, extracellular matrix organization, and stress tolerance. CREB3L2 acts in concert with other bZIP transcription factors such as ATF6 and CREB3L1 to regulate protein folding and secretion.The CREB3L2 gene is located on chromosome 7q33 and is highly expressed in secretory tissues such as cartilage, liver, and endocrine glands. It contributes to normal skeletal development and cellular adaptation to increased protein synthesis demands. CREB3L2 is also a critical determinant of collagen biosynthesis during chondrogenesis and wound repair.Pathologically, translocations involving CREB3L2 and FUS lead to low-grade fibromyxoid sarcoma, resulting in constitutive transcriptional activation and altered differentiation. Aberrant CREB3L2 activity has also been implicated in metabolic and neurodegenerative disorders linked to ER stress. Research using CREB3L2 antibody supports studies in transcriptional control, ER stress, and tumor biology.CREB3L2 antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect ER-associated transcription factors. NSJ Bioreagents provides CREB3L2 antibody reagents optimized for studies in transcriptional regulation, protein secretion, and cellular stress responses.Structurally, Cyclic AMP-responsive element-binding protein 3-like protein 2 features a basic leucine zipper (bZIP) DNA-binding domain, an ER luminal domain involved in sensing stress signals, and a transmembrane region that anchors it to the ER. This antibody aids in studying CREB3L2's role in secretory pathway regulation, collagen production, and tumorigenic gene fusion mechanisms.
