Bacteriocins are proteinaceous toxins produced by bacteria to inhibit the growth of similar or closely related bacterial strain(s). They are typically considered to be narrow spectrum antibiotics though this has […]

Reelin is a large secreted extracellular matrix glycoprotein that helps regulate processes of neuronal migration and positioning in the developing brain by controlling cell–cell interactions. Besides this important role in […]

A homeobox is a DNA sequence found within genes that are involved in the regulation of patterns of anatomical development (morphogenesis) in animals fungi and plants.

Adrenocorticotropic hormone (ACTH) also known as corticotropin is a polypeptide tropic hormone produced and secreted by the anterior pituitary gland. It is an important component of the hypothalamic-pituitary-adrenal axis and […]

A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to a protein in a cell. It functions as an on or off switch in many […]

Retroviral integrase (IN) is an enzyme produced by a retrovirus (such as HIV) that enables its genetic material to be integrated into the DNA of the infected cell. Retroviral INs […]

Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as vegetables fruit or animals). It catalyzes the decomposition of hydrogen peroxide to water and […]

Ubiquitin is a small (8.5 kDa) regulatory protein that has been found in almost all tissues (ubiquitously) of eukaryotic organisms. It was discovered in 1975 by Goldstein and further characterized […]

The SRC Homology 3 Domain (or SH3 domain) is a small protein domain of about 60 amino acids residues first identified as a conserved sequence in the viral adaptor protein […]

Reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template a process termed reverse transcription. RT is needed for the replication of retroviruses (e.g. […]
