| big brain | <molecular biology> Neurogenic gene of Drosophila, believed to encode a product involved in cell cell communication, perhaps via gap junctions. Member of the major intrinsic protein family. (18 Nov 1997) |
| big-head | 1. In horses, usually denotes osteodystrophia fibrosa. 2. Gas gangrene infection of tissues of the head, caused by Clostridium novyi in sheep, usually young rams with head wounds. 3. Photosensitization in sheep. 4. An acute disease of young rams caused by the Clostridium novyi, C. Sordellii or, rarely, C.

| acrosomal cap | A collapsed membranous vesicle that covers the anterior part of the nucleus of the spermatozoon, derived from the acrosomal granule; the carbohydrate-rich substance of the cap is associated with hydrolytic enzymes that aid in sperm penetration of the zona pellucida of the ovum. Synonym: head cap. (05 Mar 2000) |
| apical cap | <radiology> Local pleural thickening at lung apex, ascribed incorrectly to TB, aetiology: non-specific fibrous scarring (most common), Pancoast tumour (12 Dec 1998) |

| cap | <abbreviation> Catabolite (gene) activator protein. 1. Any anatomical structure that resembles a cap or cover. 2. A protective covering for an incomplete tooth. 3. Colloquialism for restoration of the coronal part of a natural tooth by means of an artificial crown. 4. The nucleotide structure found at the 5' terminus of many eukaryotic messenger RNAs, consisting of a 7-methylguanosine connected, via its 5'-hydroxyl group, by a triphosphate group to the 5'-hydroxyl group of the first nucleoside encoded by the DNA; usually symbolised as m7G5'ppp5'N, where N is nucleoside number 1 in the transcribed mRNA and is often itself methylated; the cap is added posttranscriptionally. (05 Mar 2000) |
| cap binding protein | <molecular biology, protein> Protein (24 kD) with affinity for cap structure at 5' end of mRNA that probably assists, together with other initiation factors, in binding the mRNA to the 40S ribosomal subunit. Translation of mRNA in vitro is faster if it has a cap binding protein. (18 Nov 1997) |
| cap II RNA(nucleoside-2'-)methyltransferase | <enzyme> Converts cap i-terminated mRNA to cap II-terminated mRNA Registry number: EC 2.1.1.- Synonym: cap II methylase (26 Jun 1999) |
| cap I RNA (nucleoside-2'-)methyltransferase | <enzyme> Converts cap 0-terminated mRNA to cap i-terminated mRNA Registry number: EC 2.1.1.- Synonym: cap I methylase (26 Jun 1999) |
| Cap(m(7)GpppXm) endonuclease | <enzyme> Cleaves capped rnas to generate primers that initiate viral RNA transcription Registry number: EC 3.1.27.- Synonym: cap mgx endonuclease, decapping enzyme (26 Jun 1999) |
| cap of the ampullary crest | A gelatinous mass that overlies the hair cells of the ampullary crests of the saemicircular ducts; movement of endolymphatic fluid causes the cupula to move across the hair cells of the ampullary crest. Synonym: cap of the ampullary crest. (05 Mar 2000) |
| cap splint | A plastic or metallic fracture appliance designed to cover the crowns of the teeth and usually cemented to them. (05 Mar 2000) |
