| p57lck | <protein> Lymphoid isoform of src family tyrosine kinase. Expressed predominantly in thymocytes and peripheral T-cells. Associates with cytoplasmic domains of CD4 and CD8 and with the _ chain of the interleukin-2 receptor. (18 Nov 1997) |
|---|---|
| p60 tumour necrosis factor receptor-associated kinase | <enzyme> Interacts with and causes phosphorylation of the cytoplasmic domain of the tnf receptor Registry number: EC 2.7.10.- Synonym: p60 tnf receptor-associated kinase, p60-trak (26 Jun 1999) |
| p65 | <protein> Protein from human T-cells that has sequences in common with plastin. Major target for interleukin-2 stimulated phosphorylation. On basis of sequence has two calcium binding sites, a calmodulin binding site and two actin binding sites. (18 Nov 1997) |
| p67 deglycosylase | <enzyme> Inactivates eif-2 associated 67 kD protein by removal of n-acetylglucosamine residues Registry number: EC 3.2.1.- (26 Jun 1999) |
| p68 | <protein> See annexin, DEAD box helicases. (18 Nov 1997) |
| p68 RNA helicase | <enzyme> An RNA helicase isolated from uv-induced tumours in mice; amino acid sequence has been determined Registry number: EC 2.7.7.- Synonym: dead box helicase p68 (26 Jun 1999) |
| p70 | <protein> Group of calcium-binding proteins that interact with acidic membrane phospholipids in membranes. They contain 4 or 8 repeats of a 61 amino acid domain that folds into 5 a helices. Also known by several other names (e.g. Lipocortins, endonexins), reflecting the history of their discovery in different contexts. See: lipocortin, endonexin I & II, calpactin, p70 and calelectrin.

| PA projection | The standard frontal chest film projection; radiographic skull projection with the petrous ridge superimposed on the orbits. Synonym: posteroanterior projection. (05 Mar 2000) |
| pa X-ray | An X-ray picture in which the beams pass from back-to-front (posteroanterior). As opposed to an ap (anteroposterior) film in which the rays pass through the body from front-to-back. (12 Dec 1998) |
| Paas' disease | A familial skeletal deformation marked by coxa valga, double patella, shortening of the middle and terminal phalanges of fingers and toes, deformities of the elbows, scoliosis, and spondylitis deformans of the lumbar vertebrae; all of these manifestations may be unilateral or bilateral.
