BDNF Protein, Human (R125A, R127A, R128A, solution)

Brain Derived Neurotrophic Factor (BDNF) is a neurotrophin that belongs to NGF-beta family. BDNF can bind to its high affinity receptor TrkB and activates signal transduction cascades (IRS1/2, PI3K, Akt)^[1]. BDNF can also bind to the p75NTR, but the affinity for the p75NTR receptor is lower than for TrkB^[2]. BDNF is a neurotransmitter modulator, and is vital in maturation, survival and differentiation of neuronal populations during development. BDNF also participates in neuronal plasticity, which is essential for learning and memory. BDNF is widely expressed in the CNS^[1]. BDNF Protein, Human (R125A,R127A,R128A) is a recombinant human BDNF (A19-R247) with R125A, R127A, R128A mutations, and without tag, which is produced in E.coli.

BDNF, a neurotrophin that belongs to NGF-beta family. BDNF is widely expressed in the CNS, gut and other tissues. BDNF regulates neurodevelopmental processes, including maturation, survival and differentiation of neuronal populations, and synaptic plasticity^[1].
BDNF can bind to its high affinity receptor TrkB and activates signal transduction cascades (IRS1/2, PI3K, Akt), thereby inducing increased Ca²⁺ intake and phosphorylation of transcription factors. BDNF can also bind to the p75NTR, but the affinity for the p75NTR receptor is lower than for TrkB. The activation of p75NTR increases apoptotic and inflammatory signaling in neurons and glial cells by activation of c-Jun N-terminal kinases (JNK) and NF-κB expression, respectively^[2]. In human, decreased levels of BDNF are associated with neurodegenerative diseases (such as Parkinson's disease and Alzheimer's disease) and type 2 diabetes mellitus^[1]. Human BDNF shares >97% aa sequence identity with mouse and rat. Rat BDNF shares >99% aa sequence identity with mouse.
