NGFR Protein, Mouse (HEK293, Fc)

Customer Review

Based on 1 Customer Validation

Nerve Growth Factor Receptor (NGFR) also known as CD271, p75NTR, TNFRSF16, is a transmembrane low-affinity receptor for the neurotrophin family. NGFR has no intrinsic tyrosine kinase activity. NGFR can act as a tumour suppressor, negatively regulating cell growth and proliferation. NGF-NGFR cascade activates NF-κB, leading to inhibition of apoptosis, increases survival of schwannoma, and breast cancer cells.  NGFR Protein, Mouse (HEK293, Fc) is a recombinant protein with a C-Terminal Fc label, It consists of 243 amino acids and is produced in HEK293 cells.

Biological Activity

Description

Nerve Growth Factor Receptor (NGFR) also known as CD271, p75NTR, TNFRSF16, is a transmembrane low-affinity receptor for the neurotrophin family. NGFR has no intrinsic tyrosine kinase activity. NGFR can act as a tumour suppressor, negatively regulating cell growth and proliferation[1]. NGF-NGFR cascade activates NF-κB, leading to inhibition of apoptosis, increases survival of schwannoma, and breast cancer cells[3].  NGFR Protein, Mouse (HEK293, Fc) is a recombinant protein with a C-Terminal Fc label, It consists of 243 amino acids and is produced in HEK293 cells.

Background

Nerve Growth Factor Receptor (NGFR) is expressed not only in nervous tissue, but also in non-neuronal normal and cancer cells, such as perivascular cells, dental pulp cells, lymphoidal follicular dendritic cells, basal epithelium of oral mucosa and hair follicles, prostate basal cells and myoepithelial cells[1].
Human NGFR shares 92.45% aa sequence identity with mouse NGFR protein and 92.42% aa sequence identity with rat NGFR protein.
Nerve Growth Factor Receptor (NGFR) is a type-I transmembrane protein, a typical structure of the TNFR superfamily and devoid of intrinsic catalytic activity. NGFR signaling involves activation of NF-kB (Rel/NF-kB transcription factors) and the phosphorylation of the transcription factor c-Jun kinase (JNK), as well as increased production of ceramide, leading to gene transcription or programmed cell death[2].
NGFR induces p53-dependent apoptosis and cell growth arrest as well as suppressed tumor growth[3]. The low-affinity nerve growth factor receptor (NGFR) p75NGFR induces apoptosis in the absence of nerve growth factor (NGF) binding but enhances neural survival when bound by NGF. NGFR enhances beta-amyloid peptide toxicity[4]. NGFR signal can induce the subsequent downregulation of melanoma antigens and eventually suppress CTL activation[5].

Verified Bioactivity

Measured by its ability to inhibit NGF-dependent proliferation of TF-1 human erythroleukemic cells.The ED50 for this effect is typically 0.5-3 μg/mL in the presence of 2 ng/mL Recombinant mouse NGF.
