Related Product Information for CNTF active protein
Description: Recombinant Human CNTF Protein is produced by E. coli expression system. The target protein is expressed with sequence (Met1-Met200) of human CNTF (Accession #NP_000605.1) fused with a 6xHis tag at the C-terminus.

Background: The protein is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. The protein is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. A mutation in this protein, which results in aberrant splicing, leads to ciliary neurotrophic factor deficiency, but this phenotype is not causally related to neurologic disease.

NCBI Description

The protein encoded by this gene is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. The protein is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. A mutation in this gene, which results in aberrant splicing, leads to ciliary neurotrophic factor deficiency, but this phenotype is not causally related to neurologic disease. A read-through transcript variant composed of the upstream ZFP91 gene and CNTF sequence has been identified, but it is thought to be non-coding. Read-through transcription of ZFP91 and CNTF has also been observed in mouse. [provided by RefSeq, Oct 2010]

Uniprot Description

CNTF: CNTF is a survival factor for various neuronal cell types. Seems to prevent the degeneration of motor axons after axotomy. Belongs to the CNTF family.

Chromosomal Location of Human Ortholog: 11q12.2

Cellular Component: extracellular space; cytoplasm

Molecular Function: interleukin-6 receptor binding; growth factor activity; ciliary neurotrophic factor receptor binding

Biological Process: negative regulation of photoreceptor cell differentiation; positive regulation of cell proliferation; regulation of retinal cell programmed cell death; neuron development; negative regulation of neuron apoptosis; signal transduction; muscle morphogenesis; growth; positive regulation of tyrosine phosphorylation of Stat3 protein

Product Notes

The CNTF cntf (Catalog #AAA9139642) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: MAFTEHSPLT PHRRDLCSRS IWLARKIRSD LTALTESYVK HQGLNKNINL DSADGMPVAS TDQWSELTEA ERLQENLQAY RTFHVLLARL LEDQQVHFTP TEGDFHQAIH TLLLQVAAFA YQIEELMILL EYKIPRNEAD GMPINVGDGG LFEKKLWGLK VLQELSQWTV RSIHDLRFIS SHQTGIPARG SHYIANNKKM. It is sometimes possible for the material contained within the vial of "CNTF, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
