Primary source: FLYBASE:FBgn0001316
Locus tag: Dmel_CG17046
See related: AllianceGenome:FB:FBgn0001316
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Drosophila melanogaster
Lineage: Eukaryota; Metazoa; Ecdysozoa; Arthropoda; Hexapoda; Insecta; Pterygota; Neoptera; Endopterygota; Diptera; Brachycera; Muscomorpha; Ephydroidea; Drosophilidae; Drosophila; Sophophora
Also known as: CG17046; Dmel\CG17046; Klar; kls; marb
Summary: Enables kinesin binding activity. Involved in several processes, including larval visceral muscle development; lipid droplet transport along microtubule; and lumen formation, open tracheal system. Located in microtubule; nuclear outer membrane; and perinuclear region of cytoplasm. Colocalizes with cytoplasmic microtubule and lipid droplet. Is expressed in several structures, including embryonic primordium of adult salivary gland; eye disc; eye disc posterior to the morphogenetic furrow; larval brain; and mesectoderm. Used to study Emery-Dreifuss muscular dystrophy. [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

loss of Bocksbeutel reduced Klarsicht localization to the nucleus and resulted in a disruption in nuclear separation. Loss of Otefin increased the transcription of Klarsicht and led to premature separation of nuclei and their positioning closer to the edge of the muscle.
Title: Drosophila emerins control LINC complex localization and transcription to regulate myonuclear position.
Data indicate that mushroom body defect protein (Mud) co-localized with centromeres, Klarsicht protein and Klaroid protein.
Title: Microtubule-driven nuclear rotations promote meiotic chromosome dynamics.
Two novel isoformes of Klar delta and/or epsilon are widely expressed during development, including in the embryonic and larval nervous system as well as in ovaries.
Title: Novel isoforms of the transport regulator klar.
A new mutant allele of Klar is described with a lesion specifically in the LD domain; this lesion abolishes both droplet localization of Klar and the ability of Klar to regulate droplet motion.
Title: Targeting the motor regulator Klar to lipid droplets.
Msp-300 has a function in egg laying, normally redundant with a function of Klar.
Title: On the roles of the Drosophila KASH domain proteins Msp-300 and Klarsicht.
expressed during oogenesis and localizes to the nuclear envelope of the germ line nuclei
Title: The Drosophila KASH domain proteins Msp-300 and Klarsicht and the SUN domain protein Klaroid have no essential function during oogenesis.
Klarsicht expression is limited to differentiating cells in the eye and may be part of the trigger for apical nuclear migration.
Title: Drosophila klaroid encodes a SUN domain protein required for Klarsicht localization to the nuclear envelope and nuclear migration in the eye.
Links the nucleus to the microtubule organizing center.
Title: Drosophila klarsicht has distinct subcellular localization domains for nuclear envelope and microtubule localization in the eye.
Klar isoforms control motion and positioning of multiple organelles
Title: Organelle-specific control of intracellular transport: distinctly targeted isoforms of the regulator Klar.
klar plays a role in salivary tube development in Drosophila
Title: Epithelial tube morphology is determined by the polarized growth and delivery of apical membrane.
