Barrier-to-autointegration factor; Plays fundamental roles in nuclear assembly, chromatin organization, gene expression and gonad development. May potently compress chromatin structure and be involved in membrane recruitment and chromatin decondensation during nuclear assembly. Functions are required in both M phase and interphase of the cell cycle. Belongs to the BAF family.

Death executioner caspase related to Apopain/Yama (Decay) encodes one of the seven members of the caspase family of cysteine proteases. It has substrate specificity similar to the effector caspases encoded by Drice and Dcp-1; Belongs to the peptidase C14A family.

Lamin Dm0; Lamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin. May have a role in the localization of the LEM domain proteins Ote, bocks and MAN1 to the nuclear membrane. In spermatocytes, plays a role in maintaining type-A lamin LamC nuclear localization; regulates meiotic cytokinesis by maintaining the structure of the spindle envelope, and by contributing to the formation of the contractile ring and central spindle.

Inner nuclear membrane protein Man1; Inner nuclear membrane protein. Acts as a negative regulator of the BMP (Dpp) signaling cascade during crossvein development in pupal wings and possibly during synaptic transmission at the neuromuscular junction (NMJ). Appears to be required for pupal development and consequently transition to the adult stage. During pupal development, plays essential and redundant functions with the other LEM domain proteins; bocks and Ote.

Caspase subunit p12; Death related ICE-like caspase (Drice) encodes a major effector apoptotic caspase. It is essential for both developmental and damaged induced cell death, as well as several non-apoptotic vital cellular processes. It is activated by the product of Dark and the initiator caspase encoded by Dronc and is inhibited by the inhibitor of apoptosis encoded by Diap1; Belongs to the peptidase C14A family.

Otefin; Inner nuclear membrane protein. Involved in the attachment of membrane vesicles to chromatin during nuclear assembly, and is probably required for centrosome maturation and cell cycle progression during mitosis. Essential for differentiation of certain tissues and the maintenance of progenitor cell populations. Required for the differentiation and maintenance of male and female germline stem cells (GSCs), as well as the maintenance of somatic cells in the GSC niche. This role is likely to be independent of the BMP (Dpp) pathway that negatively regulates bam transcription during [...]

Nuclear pore complex protein Nup153; Component of the nuclear pore complex (NPC), a complex required for the trafficking across the nuclear envelope. Functions as a scaffolding element in the nuclear phase of the NPC. Essential for the nuclear import of nuclear localization signal (NLS)-containing proteins in a Importin alpha/Importin beta receptor-dependent manner. Required for nuclear import of Mad. Plays a role in chromosomal organization and gene expression regulation; stimulates transcription by promoting the formation of an open chromatin environment. Binds chromatin to nucleopor [...]

Muscle-specific protein 300 kDa (Msp300) encodes a Nesprin-like protein that is required for proper positioning of muscle nuclei, mitochondria, and neuromuscular junction.

Cyclin-dependent kinase 1 (Cdk1) encodes a catalytic protein kinase subunit that can only become active after association with either CycA, CycB or CycB3 products. The protein kinase activities of these complexes (CycA-Cdk1, CycB-Cdk1, CycB3-Cdk1) control important aspects of progression through the cell cycle. Functionally, the different Cdk1 complexes are partially redundant. They phosphorylate hundreds of target proteins and are most important for progression into and through mitotic and meiotic M phases.
