Date: Wed, 15 Dec 1999 From: Leonard Rabinow 1) Doa clones are lethal in both the germ-line and soma; 2) there are 2 different protein isoforms of Doa, one of 55 and the other of 105 kD; the 55 is nuclear and the 105 is cytoplasmic; 3) protein and RNA expression are essentially ubiquitous throughout development, in all tissues, although differences in expression levels exist; 4) sex-specific expression of the kinase is essentially identical.
