Molecular biology

By analogy with the right hand, a helix, e.g. of a polypeptide, that advances towards the C-terminus in the direction of the extended thumb as the backbone of a chain turns in the direction of the ...

inhibitor of apoptosis

Biology; Biochemistry

Inhibitor of apoptosis (IAP) proteins are present in most animal cells and regulate the sensitivity of an animal cell to apoptosis-inducing stimuli by binding to and inhibiting activated caspases, ...

enhanceosome

Biology; Biochemistry

A highly-ordered cluster of tissue-specific transcription factors that assemble at regulatory elements of a eukaryotic gene and which, by their arrangement in space, act synergistically and ...

fragment reaction assay

Biology; Biochemistry

A measure of the transferase phase of protein synthesis independent of mRNA and many ribosomal factors; i.e. the transfer of an amino acid from its position esterified to the 3'-end of a tRNA (or ...

membrane protein secretase

Biology; Biochemistry

A sheddase, a matrix metalloprotease that cleaves an exposed non-globular region (the stalk) of a protein attached to the outer surface of the plasma membrane, often a transmembrane protein, to ...

second genetic code

Biology; Biochemistry

An imprecise term that sometimes refers to the nature of the amino acid residues of a protein which determine its secondary and tertiary structure, and sometimes to the features of a tRNA molecule ...

founder effect

Biology; Biochemistry

The prominence in a population of a rare allele or haplotype due to the population's being historically isolated and having been descended from a small number individuals, among whom was one ...
