Description
Product Characteristics:
Molecular chaperone that localizes to genomic response elements in a hormone-dependent manner and disrupts receptor-mediated transcriptional activation, by promoting disassembly of transcriptional regulatory complexes. Belongs to the p23/wos2 family.
Subcellular location: Cytoplasm
Synonyms: Telomerase Binding Protein_P23, Prostaglandin E synthase 3, Cytosolic prostaglandin E2 synthase, cPGES, Telomerase-binding protein p23, Hsp90 co-chaperone, Progesterone receptor complex p23, PTGES3, P23, TEBP, TEBP_HUMAN.
Target Information: The protein encoded by this gene (p35) is a neuron-specific activator of cyclin-dependent kinase 5 (CDK5)\, the activation of CDK5 is required for proper development of the central nervous system. The p35 form of this protein is proteolytically cleaved by calpain, generating a p25 form. The cleavage of p35 into p25 results in relocalization of the protein from the cell periphery to nuclear and perinuclear regions. P25 deregulates CDK5 activity by prolonging its activation and changing its cellular location. The p25 form accumulates in the brain neurons of patients with Alzheimer's disease. This accumulation correlates with an increase in CDK5 kinase activity, and may lead to aberrantly phosphorylated forms of the microtubule-associated protein tau, which contributes to Alzheimer's disease.
