The Drosophila kismet gene is related to chromatin-remodeling factors and is required for both segmentation and segment identity.

Abstract: The Drosophila kismet gene was identified in a screen for dominant suppressors of Polycomb, a repressor of homeotic genes. Here we show that kismet mutations suppress the Polycomb mutant phenotype by blocking the ectopic transcription of homeotic genes. Loss of zygotic kismet function causes homeotic transformations similar to those associated with loss-of-function mutations in the homeotic genes Sex combs reduced and Abdominal-B. kismet is also required for proper larval body segmentation. Loss of maternal kismet function causes segmentation defects similar to those caused by mutations in the pair-rule gene even-skipped. The kismet gene encodes several large nuclear proteins that are ubiquitously expressed along the anterior-posterior axis. The Kismet proteins contain a domain conserved in the trithorax group protein Brahma and related chromatin-remodeling factors, providing further evidence that alterations in chromatin structure are required to maintain the spatially restricted patterns of homeotic gene transcription.

Toward Teaching a Robot "Infant" using Emotive Communication Acts

Abstract: This paper presents ongoing work towards building an autonomous robot that learns in a social context. The mode of social interaction is that of a caretaker-infant pair where a human acts as the caretaker for the robot. By placing our robot, Kismet, in an environment with a human caretaker who actively assists and guides Kismet's learning, this work explores robot learning in a similar environment to that of a developing infant. In doing so, this approach attempts to take advantage of this special sort of environment and the social interactions it affords in facilitating and constraining learning. This paper proposes an approach where emotive channels of communication are employed during social robot-human interactions to shape and guide what the robot learns. keywords: human-robot interaction, scaffolding, emotions

Human kismet protein ((hkis)) acts as an oncogene

Abstract: A human oncogene termed hkis and its protein product can be used, inter alia, as diagnostic and prognostic tools for neoplastic disorders. The human hkis gene can also be used to identify a q13 region of human chromosome 16.
