General description

BDNF/NT-3 growth factors receptor (EC 2.7.10.1; UniProt Q63604; also known as GP145-TrkB/GP95-TrkB, Trk-B, TrkB tyrosine kinase, Neurotrophic tyrosine receptor kinase type 2, Neural receptor protein-tyrosine kinase) is encoded by the Ntrk2 gene (also known as RATTRKB1, Trkb, TRKB1) in rat (Gene ID 25054). Neurotrophins mediate a wide range of neuronal functions, including survival, differentiation, growth, and death, via two classes of transmembrane receptors, the Trk receptor tyrosine kinase and the p75 neurotrophin receptor. While nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and NT-4 all bind the p75 receptor, TrkA is selective for NGF, TrkB is selective for BDNF and NT-4, and TrkC is selective for NT-3. TrkA and TrkB receptors can also be activated by ligands of the G-protein-coupled receptor (GPCRs), including the nucleoside adenosine or adenosine agonists, such as CGS 21680 and the pituitary adenylate cyclase-activating polypeptide (PACAP). In addition to transactivation via GPCRs and glucocorticoids are also reported to promote TrkA/B/C activation due to signaling cross-talk between Trk and GC receptor (GR).

Specificity

This polyclonal antibody selectively detects BDNF-induced pTyr816 phosphorylation of both glycosylated (145 kDa) and unprocessed (110 kDa) TrkB in primary embryonic rat E18 hippocampal neurons, but not NGF-induced pTyr490 or pTyr794 phosphorylation of TrkA in primary embryonic septal neurons (PMID 18347336).

Immunogen

Epitope: Near C-terminus
Linear peptide corresponding to rat TrkB sequence near the C-terminus with phosphorylated Tyr816.

Application

Detect phospho-TrkB (Tyr816) using this Anti-phospho-TrkB (Tyr816) Antibody validated for use in Western Blotting, Immunocytochemistry, Immunoprecipitation and Immunohistochemistry.

Menopause is a risk factor for depression. Although 1,3-dicaffeoylquinic acid (1,3-diCQA), a phenolic compound in Arctium lappa (A. lappa) root, has various health benefits, its effects on menopausal depression remain to be determined. Therefore, this study investigates the antidepressant-like effects

It is widely accepted that mitochondria have a direct impact on neuronal function and survival. Oxidative stress caused by mitochondrial abnormalities play an important role in the pathophysiology of lipopolysaccharide (LPS)-induced memory impairment. Elamipretide (SS-31) is a novel mitochondrion-targeted antioxidant.
