Kinesin-like calmodulin-binding protein (KCBP) is a novel member of the kinesin superfamily that is involved in cell division and trichome morphogenesis. KCBP is unique among all known kinesins in having a myosin tail homology-4 region in the N-terminal tail and a calmodulin-binding region following the motor domain. Calcium, through calmodulin, has been(More)
The genes of the trithorax group (trxG) in Drosophila melanogaster are required to maintain the pattern of homeotic gene expression that is established early in embryogenesis by the transient expression of the segmentation genes. The precise role of each of the diverse trxG members and the functional relationships among them are not well understood. Here,(More)
Many proteins of the SNF2 family, which share a similar DNA-dependent ATPase/putative helicase domain, are involved in global transcriptional control and processing of DNA damage. We report here the partial cloning and characterization of 89B helicase, a gene encoding a new Drosophila melanogaster member of the SNF2 family. 89B Helicase protein shows a high(More)
Germband retraction in Drosophila melanogaster, like most embryonic morphogenetic events in this organism and in higher eukaryotes, is not well understood. We have taken several approaches to study the relationships between previously identified mutations (u-shaped, serpent, hindsight and tailup) that selectively cause germband retraction defects in(More)
