| zipper | <molecular biology> Motif found in certain DNA binding proteins. In a region of approximately 35 amino acids, every seventh is a leucine. This facilitates dimerisation of two such proteins to form a functional transcription factor. Examples of proteins containing leucine zippers are products of the proto-oncogenes myc, fos and jun.

| zipper protein kinase | <enzyme> A putative serine/threonine protein kinase of 859 amino acids; has a leucine-zipper domain; has been sequenced; genbank u07358 Registry number: EC 2.7.10.- Synonym: zpk protein, leucine-zipper protein kinase (26 Jun 1999) |
| zippering | <cell biology> Process suggested to occur in phagocytosis in which the membrane of the phagocyte covers the particle by a progressive adhesive interaction. The evidence for such a mechanism comes from experiments in which capped B-cells are only partially internalised, whereas those with a uniform opsonising coat of antiIgG are fully engulfed.

| dual leucine zipper bearing kinase | <enzyme> A serine/threonine kinase but hybrid between microtubule-associated protein kinase kinase kinases and the fibroblast growth factor receptor family; genbank u14636; do not confuse with the neoplasm protein dlk Registry number: EC 2.7.10.- Synonym: dlk kinase (26 Jun 1999) |
