AKT

AKT2, also known as Protein Kinase B (PKB), is a serine/threonine-specific protein kinase that plays a key role in multiple cellular processes such as glucose metabolism, apoptosis, cell proliferation, transcription and cell migration. The name Akt does not refer to its function. The "Ak" in Akt was a temporary classification name for a mouse strain originally bred and maintained by Jacob Furth that developed spontaneous thymic lymphomas. The "t" stands for 'thymoma'; the letter was added when a transforming retrovirus was isolated... [Lire la suite]

Axokine and CNTF

Axokine is a modified version of human Ciliary neurotrophic factor with a 15 amino acid truncation of the C terminus and two amino acid substitutions, which is three to five times more potent than CNTF in in vitro and in vivo assays and has improved stability properties. Like CNTF it is a neurotrophic factor, and may stimulate nerve cells to survive. It was tested in the 1990s as a treatment for amyotrophic lateral sclerosis. It did not improve muscle control as much as expected, but trial participants did report a loss of appetite.

Satiety effects of CNTF

In 2001, CNTF was reported that in a human study examining the usefulness of CNTF for treatment of motor neuron disease, CNTF produced an unexpected and substantial weight loss in the study subjects. Further investigation revealed that CNTF could reduce food intake without causing hunger or stress, making it a candidate for weight control in leptin resistant subjects, as CNTF is believed to operate like leptin, but by a non-leptin pathway.

Ciliary neurotrophic factor

CNTF encoded by this gene is a polypeptide hormone and nerve growth factor whose actions have mainly been studied in the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations including astrocytes. 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... [Lire la suite]

Entrez Gene summary for CEACAM1

CEACAM1 encodes a member of the carcinoembryonic antigen (CEA) gene family, which belongs to the immunoglobulin superfamily. Two subgroups of the CEA family, the CEA cell adhesion molecules and the pregnancy-specific glycoproteins, are located within a 1.2 Mb cluster on the long arm of chromosome 19. Eleven pseudogenes of the CEA cell adhesion molecule subgroup are also found in the cluster. The encoded protein was originally described in bile ducts of liver as biliary glycoprotein. Subsequently, it was found to be a cell-cell... [Lire la suite]

Source / Purification of CEACAM1

CEACAM1 Antibody detects endogenous levels of total CEACAM1 protein. Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala460 of human CEACAM1 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Post-translational modification of CBP Protein

Methylation of the KIX domain by CARM1 blocks association with CBP. This results in the blockade of CREB signaling, and in activation of apoptotic response By similarity. Phosphorylated upon DNA damage, probably by ATM or ATR. Phosphorylated by CHUK/IKKA at Ser-1382 and Ser-1386; these phosphorylations promote cell growth by switching the binding preference of CREBBP from TP53 to NF-kappa-B.

Scientific Background of CBP Protein

CBP or CREB-binding protein is a nuclear transcriptional coactivator protein that binds specifically to the PKA-phosphorylated form of the CREB protein. Microinjection of an anti-CBP antiserum into fibroblasts leads to inhibition of transcription from a cAMP promoter. CBP can also cooperates with upstream activators, such as JUN. When JUN is phosphorylated at the transcriptionally stimulatory sites ser73 and ser63, it binds CBP with comparable affinity to CREB. Insulin signaling may directly regulate many cAMP signaling pathways at... [Lire la suite]
