| POU domain | <molecular biology> A conserved protein domain of around 150 amino acids, composed of a 20 amino acid homeobox domain and a larger POU specific domain and so is the target of some transcription factors. Named POU (Pit Oct Unc) after 3 such proteins: Pit 1 regulates expression of certain pituitary genes, Oct 1 and 2, that bind an octamer sequence in the promoters of histone H2A and some immunoglobulin genes and Unc 86, involved in nematode sensory neuron development.

| skin pore | The surface opening of the duct of a sweat gland. Synonym: porus sudoriferus, porus, pore, skin pore. (05 Mar 2000) |
| soil pore | An area within soil occupied by either air or water, resulting from the arrangement of individual soil particles. (09 Oct 1997) |
| nuclear pore | <cell biology> Openings in the nuclear envelope, diameter about 10 nm, through which molecules such as nuclear proteins synthesised in the cytoplasm) and mRNA must pass. Pores are generated by a large protein assembly. (18 Nov 1997) |
| sweat pore | The surface opening of the duct of a sweat gland. Synonym: porus sudoriferus, porus, pore, skin pore. (05 Mar 2000) |
| dilated pore | An enlarged follicular opening of the skin, with a keratinous plug and occasional lanugo or mature hair. Synonym: acquired trichoepithelioma. (05 Mar 2000) |
| dinucleotide domain | A structural domain in certain proteins that binds NAD+ or NADP+. Synonym: dinucleotide domain. (05 Mar 2000) |
| domain | <molecular biology> Used to describe a part of a molecule or structure that shares common physico chemical features, for example hydrophobic, polar, globular, helical domains or properties for example DNA binding domain, ATP binding domain. (18 Nov 1997) |
| internal acoustic pore | The inner opening of the internal acoustic meatus on the posterior surface of the petrous part of the temporal bone. Synonym: porus acusticus internus, internal acoustic foramen, internal acoustic pore, auditory pore, internal auditory foramen, orifice of internal acoustic meatus. (05 Mar 2000) |
| taste pore | The minute opening of a taste bud on the surface of the oral mucosa through which the gustatory hairs of the specialised neuroepithelial gustatory cells project. Synonym: porus gustatorius, taste pore. (05 Mar 2000) |
| EGF like domain | Region of 30-40 amino acids containing 6 cysteines found originally in EGF and also in a range of proteins involved in cell signalling. Examples: TGF _, amphiregulin, urokinase, tissue plasminogen activator, complement C6 C9, fibronectin, laminin (each subunit at least 13 times), nidogen, selectins. It is also found in the Drosophila gene products: Notch (36 times) Delta, Slit, Crumbs, Serrate. (18 Nov 1997) |
| exit domain | <molecular biology> One of the two main binding sites on the ribosome molecule. The finished portion of the polypeptide being translated is attached to this site and leaves the ribosome from this site when the entire polypeptide is finished. (09 Oct 1997) |
| external acoustic pore | The orifice of the external acoustic meatus in the tympanic portion of the temporal bone. Synonym: porus acusticus externus, external acoustic foramen, external acoustic pore, external auditory pore, external auditory foramen, orifice of external acoustic meatus. (05 Mar 2000) |
| frequency domain | The expression of a function by its amplitude and phase at each component frequency, usually as determined by Fourier analysis. (05 Mar 2000) |
