Ubiquitin-protein transferase activity. It is involved in the biological process described with: sperm individualization; protein ubiquitination; defense response to bacterium.

UPF0518 protein CG3558.

WW domain-containing adapter protein with coiled-coil homolog; Acts as a linker between gene transcription and histone H2B monoubiquitination at 'Lys-118' (By similarity). Regulates the cell- cycle checkpoint activation in response to DNA damage (By similarity). Positive regulator of amino acid starvation-induced autophagy. Also acts as a negative regulator of basal autophagy. Positively regulates Tor activity. Promotes, in an energy-dependent manner, the assembly of the TTT complex and the RUVBL complex composed of pont and rept into the TTT- RUVBL complex (By similarity). This leads [...]

Protein bicaudal D; This protein is essential for differentiation. It may play a role in localizing of Nanos (a maternal determinant) activity in oocytes. During oogenesis, plays a specific role, together with Rab6 but independently of Sec5, in the polarization of the oocyte microtubule cytoskeleton, in oskar mRNA localization and in the anterodorsal secretion of grk. Plays a role in the biogenesis of annulate lamellae containing nuclear pore complex components.

Protein crossbronx-like; Belongs to the ubiquitin-conjugating enzyme family. FTS subfamily.

DNA replication licensing factor MCM4; Acts as component of the Mcm2-7 complex (Mcm complex) which is the putative replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the Mcm2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differential [...]

ATP synthase protein 8; Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subuni [...]

Dihydrofolate reductase (Dhfr) encodes an NADPH-dependent enzyme used to convert folic acid and dihydrofolate to tetrahydrofolate, which is used as a cofactor for the biosynthesis of purines, thymidylate, and several amino acids. Dhfr product contributes to cell proliferation and cell growth.

Nuclear factor I, isoform B; DNA-binding transcription factor activity, RNA polymerase II-specific. It is involved in the biological process described with: positive regulation of transcription by RNA polymerase II; negative regulation of transcription by RNA polymerase II.
