Indoleamine-pyrrole 2,3-dioxygenase (IDO or INDO) is involved in tryptophan metabolism
Indoleamine-pyrrole 2,3-dioxygenase (IDO or INDO EC 1.13.11.52) is a heme-containing enzyme physiologically expressed in a number of tissues and cells, such as the small intestine, lungs, female genital tract or placenta. In humans is encoded by the IDO1 gene. IDO is involved in tryptophan metabolism. It is one of three enzymes that catalyze the first and rate-limiting step in the kynurenine pathway, the O2-dependent oxidation of L-tryptophan to N-formylkynurenine, the others being indolamine-2,3-dioxygenase 2 (IDO2) and tryptophan 2,3-dioxygenase…

p300-CBP coactivator family – clinical significance
Mutations in CBP, and to a lesser extent p300, are the cause of Rubinstein-Taybi Syndrome, which is characterized by severe mental retardation. These mutations result in the loss of one copy of the gene in each cell, which reduces the amount of CBP or p300 protein by half. Some mutations lead to the production of a very…

Histone acetyltransferase p300
Histone acetyltransferase p300 also known as p300 HAT or E1A-associated protein p300 (where E1A = adenovirus early region 1A) also known as EP300 or p300 is an enzyme that, in humans, is encoded by the EP300 gene. It functions as histone acetyltransferase that regulates transcription of genes via chromatin remodeling by allowing histone proteins to wrap DNA less tightly. This enzyme plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions…

CBP has been shown to play a role in every stage of tumor development
Due to its critical role in regulation of cell proliferation, growth, migration and apoptosis, it is considered to be an oncogene, or tumor suppressor. Contrarily To date, increased CBP activity has been implicated in a variety of different malignancies including breast cancer, lung cancer, prostate cancer, colorectal cancer, acute leukemias, head and neck cancer, and many others. According to the Catalog…

Cadherin-1
Cadherin-1 or Epithelial cadherin(E-cadherin), (not to be confused with the APC/C activator protein CDH1) is a protein that in humans is encoded by the CDH1gene.[5] Mutations are correlated with gastric, breast, colorectal, thyroid, and ovarian cancers. CDH1 has also been designated as CD324 (cluster of differentiation 324). It is a tumor suppressor gene.[6][7] History The discovery of cadherin cell-cell adhesion proteins is attributed to Masatoshi Takeichi, whose experience…
